description: This skill should be used when the user asks to "make a video ad", "create an animated ad", "build a performance/UGC-style ad", "batch-produce ad creative variations", "generate ad variants for A/B testing", "swap headline/offer/CTA across many ad versions", or "export one ad in multiple aspect ratios for Meta/TikTok/Reels". Covers ad hook structures, hook→CTA message-match, data-driven variant generation (1 template × CSV = N ads), multi-aspect export, and platform specs.

# Ad Creative Video
|
||||||
|
|
||||||
|
Build ONE motion-graphics ad template, then mass-produce variants from a data table — different hooks, offers, CTAs, and products — so a performance marketer can A/B test dozens of versions across placements and aspect ratios. The craft is making the template fully data-driven and message-matched, so 40 variants stay on-brand and only the tested variable changes.
|
||||||
|
|
||||||
|
## When to use
|
||||||
|
|
||||||
|
- Performance/UGC-style video ads where the first 1.5–3s must stop the scroll.
|
||||||
|
- Batch variant generation: one template rendered against many rows (headline/offer/CTA/product swaps) for A/B testing.
|
||||||
|
- Multi-aspect export of the same ad for Meta Feed, Reels/Stories, TikTok, YouTube.
|
||||||
|
|
||||||
|
Not for sale/discount countdown promos, and not for testimonial/review-driven ads — those are different structures. Stay on the batch-variation, test-everything angle.
|
||||||
|
|
||||||
|
## The two rules that make variants worth running
|
||||||
|
|
||||||
|
1. **Isolate one variable per variant.** A test only teaches something if exactly one thing changes. Hold layout, motion, colors, and timing constant; swap *only* the field under test (hook, or offer, or CTA). Mixing two changes makes the winner uninterpretable.
|
||||||
|
2. **Message-match the hook to the CTA.** The promise made in the first 3 seconds must be the promise the button pays off. A "stop wasting 2 hours a day" hook ends on "Save 2 hours — try free," not a generic "Shop now." The hook and CTA are a matched pair in every row of the data table.
|
||||||
|
|
||||||
|
## Ad anatomy (15–30s)
|
||||||
|
|
||||||
|
| Beat | Job | Budget |
|
||||||
|
|---|---|---|
|
||||||
|
| Hook (0–3s) | Stop the scroll; state the problem or pattern-interrupt | 0–3s |
|
||||||
|
| Context | Make the viewer feel the problem / agitate | 3–8s |
|
||||||
|
| Payoff | Show the product as the solution, one clear benefit | 8–18s |
|
||||||
|
| Proof | One concrete number, demo, or result | 18–25s |
|
||||||
|
| CTA (last 3s) | Single action, message-matched to the hook | hold ≥2s |
|
||||||
|
|
||||||
|
Land the hook's emotional trigger before the 2-second mark — judgment forms in ~1.7s and scroll speed keeps rising. Test the hook FIRST; it moves CPA more than any other element.
|
||||||
|
|
||||||
|
## Hook taxonomy (the field you vary most)
|
||||||
|
|
||||||
|
| Hook type | Template | When it wins |
|
||||||
|
|---|---|---|
|
||||||
|
| Problem-first | "I didn't realize how much X was costing me until…" | pain is felt but unnamed |
|
||||||
|
| Pattern interrupt | "This is going to sound controversial, but…" | crowded feed, generic category |
|
||||||
|
| Curiosity gap | "Nobody talks about the one thing that…" | educated, skeptical audience |
|
||||||
|
| Immediate benefit | "Cut your X in half in 7 days" | clear, quantifiable outcome |
|
||||||
|
| Direct callout | "If you do X every morning, stop." | sharp audience segment |
|
||||||
|
|
||||||
|
Keep a column of 5–10 hook strings and let the batch render produce one ad per hook against the same body — that is the cleanest hook test possible.
|
||||||
|
|
||||||
|
## Data-driven template (everything is a prop)
|
||||||
|
|
||||||
|
Hardcode nothing the marketer might A/B test. The composition reads a single `variant` object; the renderer never edits the component. Make every animated value a pure function of `useCurrentFrame()` so each frame renders deterministically (no CSS transitions, no library timers — they desync the render).
|
||||||
|
|
||||||
|
```tsx
|
||||||
|
import {useCurrentFrame, interpolate, AbsoluteFill, useVideoConfig} from "remotion";
|
||||||
|
|
||||||
|
type Variant = {hook: string; benefit: string; proof: string; cta: string; bg: string; accent: string};
|
||||||
|
|
||||||
|
export const AdTemplate: React.FC<{v: Variant}> = ({v}) => {
|
||||||
|
const frame = useCurrentFrame(); const {fps} = useVideoConfig();
|
||||||
|
const hookIn = interpolate(frame, [0, 8], [40, 0], {extrapolateRight: "clamp"});
|
||||||
|
const ctaIn = interpolate(frame, [fps * 22, fps * 23], [0, 1], {extrapolateLeft: "clamp", extrapolateRight: "clamp"});
|
||||||
|
return (
|
||||||
|
<AbsoluteFill style={{background: v.bg, fontFamily: "Inter, sans-serif"}}>
|
||||||
|
<h1 style={{transform: `translateY(${hookIn}px)`, opacity: interpolate(frame,[0,8],[0,1])}}>{v.hook}</h1>
|
||||||
|
{frame > fps * 8 && <p>{v.benefit}</p>}
|
||||||
|
{frame > fps * 18 && <strong>{v.proof}</strong>}
|
||||||
|
<button style={{opacity: ctaIn, background: v.accent}}>{v.cta}</button>
|
||||||
|
</AbsoluteFill>
|
||||||
|
);
|
||||||
|
};
|
||||||
|
```
|
||||||
|
|
||||||
|
See `references/batch-ad-pipeline.md` for the complete template, the CSV→props parser with validation, and the brand-lock theme object.
|
||||||
|
|
||||||
|
## 1 template × CSV = N variants
|
||||||
|
|
||||||
|
The payoff: author the ad once, then let a CSV drive the matrix. Each row is one fully-formed, message-matched variant. Render once per row.
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# variants.csv: id,hook,benefit,proof,cta,bg,accent → one MP4 per row
|
||||||
|
node csv-to-props.js variants.csv ./props # writes props/<id>.json per row
|
||||||
|
for f in props/*.json; do
|
||||||
|
id=$(basename "$f" .json)
|
||||||
|
npx remotion render AdTemplate "out/${id}.mp4" --props="$f"
|
||||||
|
done
|
||||||
|
```
|
||||||
|
|
||||||
|
To build a clean test matrix, hold every column constant and vary one: 5 hooks × 1 body = 5 ads (hook test); then take the winning hook × 3 CTAs (CTA test). `references/batch-ad-pipeline.md` has a matrix generator that expands variable lists into the CSV so combinatorial tests stay one-variable-at-a-time.
|
||||||
|
|
||||||
|
## Multi-aspect export
|
||||||
|
|
||||||
|
Each placement wants a native aspect. Compose against a center safe zone so one master reframes cleanly to all of them — don't letterbox, re-center.
|
||||||
|
|
||||||
|
| Aspect | Placements | Resolution | Keep-clear safe zone |
|
||||||
|
|---|---|---|---|
|
||||||
|
| 9:16 | Reels, Stories, TikTok In-Feed | 1080×1920 | top ~14%, bottom ~20–35% (UI/caption), sides ~6% |
|
||||||
|
| 4:5 | Meta Feed (best feed real estate) | 1080×1350 | center 90%; CTA out of bottom 10% |
|
||||||
|
| 1:1 | Feed, broad reach | 1080×1080 | center square survives every crop |
|
||||||
|
| 16:9 | YouTube, in-stream | 1920×1080 | center 90% |
|
||||||
|
|
||||||
|
Design the hook text, product, and CTA inside the **1:1 center square** so they survive every crop. Drive aspect from a prop and render each per variant:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
for ar in 9x16 4x5 1x1; do
|
||||||
|
npx remotion render AdTemplate "out/${id}-${ar}.mp4" --props="props/${id}.json" \
|
||||||
|
--props-merge="{\"aspect\":\"${ar}\"}"
|
||||||
|
done
|
||||||
|
```
|
||||||
|
|
||||||
|
Keep critical content out of the 9:16 bottom third — that is where the platform stacks captions, the CTA button, and the username. `references/platform-specs.md` has exact pixel safe zones and per-platform duration/format limits.
|
||||||
|
|
||||||
|
## Output checklist
|
||||||
|
|
||||||
|
- One variable per variant; layout/motion/timing identical across a test.
|
||||||
|
- Hook lands its trigger before 2s; hook and CTA are message-matched in every row.
|
||||||
|
- Every animated value is a pure function of `useCurrentFrame()` — no CSS/library timers.
|
||||||
|
- Dataset is a prop; nothing testable is hardcoded; one template renders the whole CSV.
|
||||||
|
- Each variant exported 9:16 + 4:5 + 1:1 (+16:9 if needed), key content in the center square.
|
||||||
|
- Brand stays locked across all variants via a single theme object.
|
||||||
|
|
||||||
|
## Deliver & verify (rendered stills → MP4)
|
||||||
|
|
||||||
|
> **Packaged helper** (`scripts/`): tile your stills with `scripts/contact-sheet.sh sheet.png f-hook.png f-mid.png f-end.png`, then assert the encode with `scripts/probe-mp4.sh out.mp4 [WxH] [fps]`. See `scripts/README.md`.
|
||||||
|
|
||||||
|
**Output contract:**
|
||||||
|
- A Remotion ad template registered as `<Composition>` (+ zod `schema` + `defaultProps`), every animated value frame-driven (no CSS transitions / library timers / `Date.now()` / `Math.random()`).
|
||||||
|
- Deliverable = the rendered `out/*.mp4` per variant per aspect (plus the project + CSV, so the marketer re-renders on new rows).
|
||||||
|
|
||||||
|
**Verify loop — render stills → inspect → encode.** Cheap PNGs first, full encode only once they're clean. Render with the **shipped** props (the real row), not just `defaultProps`.
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Frame-exact stills across the hook→CTA arc, with a real variant's props
|
||||||
|
npx remotion still AdTemplate out/f-hook.png --frame=12 --props=props/v1.json # hook readable < 2s
|
||||||
|
npx remotion still AdTemplate out/f-mid.png --frame=300 --props=props/v1.json # benefit/proof
|
||||||
|
npx remotion still AdTemplate out/f-cta.png --frame=689 --props=props/v1.json # CTA, message-matched
|
||||||
|
# inspect each: fidelity (hook / offer / proof / CTA text exact, brand bg+accent right)
|
||||||
|
# AND artifacts (text overflow, off-canvas, CTA inside the 9:16 bottom third, missing font, wrong row binding)
|
||||||
|
```
|
||||||
|
|
||||||
|
**Multi-aspect / batch — verify one variant in EACH aspect before batch-rendering the matrix.** A layout bug repeats across every row × aspect; catch it once.
|
||||||
|
|
||||||
|
```bash
|
||||||
|
for ar in 9x16 4x5 1x1; do # one representative variant, every target aspect
|
||||||
|
npx remotion still AdTemplate "out/v1-${ar}.png" --frame=300 \
|
||||||
|
--props=props/v1.json --props-merge="{\"aspect\":\"${ar}\"}"
|
||||||
|
done
|
||||||
|
# stills clean in all aspects? → then batch-render every row × aspect:
|
||||||
|
for f in props/*.json; do id=$(basename "$f" .json); for ar in 9x16 4x5 1x1; do
|
||||||
|
npx remotion render AdTemplate "out/${id}-${ar}.mp4" --props="$f" --props-merge="{\"aspect\":\"${ar}\"}"
|
||||||
|
done; done
|
||||||
|
npx remotion render AdTemplate out/demo.gif --codec=gif --props=props/v1.json # README demo
|
||||||
|
```
|
||||||
|
|
||||||
|
**Before you finish:**
|
||||||
|
1. `npx remotion still` renders cleanly at hook / mid / CTA — no errors, no missing fonts/assets.
|
||||||
|
2. Hook/offer/proof/CTA text exact and brand colors right; nothing in the 9:16 bottom third or outside the center safe zone.
|
||||||
|
3. Frame-driven only — no CSS/library timers, `Date.now()`, or `Math.random()`.
|
||||||
|
4. Shipped row's props render correctly (not just `defaultProps`); one variable per variant holds.
|
||||||
|
5. One variant verified in 9:16 + 4:5 + 1:1 before the batch; MP4s play; (optional) GIF for the README.

# Batch Ad Pipeline — full template, parser, matrix, render
|
||||||
|
|
||||||
|
This is the complete, runnable implementation behind the SKILL.md overview: a data-driven Remotion ad template, a CSV→props parser with validation, a one-variable test-matrix generator, a brand-lock theme, and the batch + multi-aspect render scripts. Hardcode nothing a marketer might want to A/B test.
|
||||||
|
|
||||||
|
## 1. The brand-lock theme
|
||||||
|
|
||||||
|
Keep every brand-controlled value in one object so 40 variants stay consistent and only the *tested* fields change per row. The variant data supplies copy and per-campaign accents; the theme supplies the locked look.
|
||||||
|
|
||||||
|
```ts
|
||||||
|
// theme.ts
|
||||||
|
export const theme = {
|
||||||
|
fontFamily: "Inter, system-ui, sans-serif",
|
||||||
|
ink: "#0B0B0F",
|
||||||
|
paper: "#FFFFFF",
|
||||||
|
radius: 20,
|
||||||
|
hookSize: 76, // px, on the 1080-wide master
|
||||||
|
bodySize: 44,
|
||||||
|
proofSize: 52,
|
||||||
|
ctaSize: 40,
|
||||||
|
pad: 80, // outer padding; also the side safe margin
|
||||||
|
durationInSeconds: 25,
|
||||||
|
} as const;
|
||||||
|
```
|
||||||
|
|
||||||
|
## 2. Aspect config
|
||||||
|
|
||||||
|
Drive layout from a single aspect prop so one composition reframes to every placement. Dimensions and the keep-clear bottom band differ per aspect.
|
||||||
|
|
||||||
|
```ts
|
||||||
|
// aspects.ts
|
||||||
|
export type Aspect = "9x16" | "4x5" | "1x1" | "16x9";
|
||||||
|
export const ASPECTS: Record<Aspect, {w: number; h: number; bottomSafe: number}> = {
|
||||||
|
"9x16": {w: 1080, h: 1920, bottomSafe: 540}, // captions + CTA + username stack here
|
||||||
|
"4x5": {w: 1080, h: 1350, bottomSafe: 135},
|
||||||
|
"1x1": {w: 1080, h: 1080, bottomSafe: 110},
|
||||||
|
"16x9": {w: 1920, h: 1080, bottomSafe: 110},
|
||||||
|
};
|
||||||
|
```
|
||||||
|
|
||||||
|
## 3. The data-driven template
|
||||||
|
|
||||||
|
Every animated value is a pure function of `useCurrentFrame()` — no CSS transitions, no GSAP/library timers (they desync deterministic rendering and flicker in the export). The component reads one `variant` plus an `aspect`; the renderer never edits this file.
|
||||||
|
|
||||||
|
```tsx
|
||||||
|
// AdTemplate.tsx
|
||||||
|
import {
|
||||||
|
AbsoluteFill, useCurrentFrame, useVideoConfig, interpolate, spring, Sequence,
|
||||||
|
} from "remotion";
|
||||||
|
import {theme} from "./theme";
|
||||||
|
import {ASPECTS, Aspect} from "./aspects";
|
||||||
|
|
||||||
|
export type Variant = {
|
||||||
|
id: string;
|
||||||
|
hook: string; // 0–3s scroll-stopper
|
||||||
|
benefit: string; // the single payoff claim
|
||||||
|
proof: string; // one concrete number / result
|
||||||
|
cta: string; // message-matched to the hook
|
||||||
|
accent: string; // per-campaign accent color
|
||||||
|
bg: string; // background color
|
||||||
|
};
|
||||||
|
|
||||||
|
export const AdTemplate: React.FC<{v: Variant; aspect: Aspect}> = ({v, aspect}) => {
|
||||||
|
const frame = useCurrentFrame();
|
||||||
|
const {fps} = useVideoConfig();
|
||||||
|
const {bottomSafe} = ASPECTS[aspect];
|
||||||
|
|
||||||
|
// Hook rises + fades in over the first 8 frames, holds, then eases up and out at 8s.
|
||||||
|
const hookY = interpolate(frame, [0, 8], [48, 0], {extrapolateRight: "clamp"});
|
||||||
|
const hookOpacity =
|
||||||

interpolate(frame, [fps * 7, fps * 8], [1, 0], {extrapolateLeft: "clamp", extrapolateRight: "clamp"});
|
||||||
|
|
||||||
|
// CTA springs in for impact in the last 3s and holds.
|
||||||
|
const ctaProgress = spring({frame: frame - fps * 22, fps, config: {damping: 14, stiffness: 120}});

## 4. Register the composition (aspect + variant as props)
|
||||||
|
|
||||||
|
```tsx
|

// Root.tsx
|

|
import {Composition} from "remotion";
|

|
import {AdTemplate} from "./AdTemplate";
|
||||||
|
import {ASPECTS} from "./aspects";
|
||||||
|
import {theme} from "./theme";
|
||||||
|
|
||||||
|
const defaultVariant = {
|
||||||
|
id: "demo", hook: "Spending 2 hrs/day on reports?", benefit: "Auto-build them in one click.",
|
||||||
|
proof: "Teams save 11 hrs a week.", cta: "Save 2 hours — try free", accent: "#4F46E5", bg: "#FFFFFF",
|
||||||
|
};
|
||||||
|
|
||||||
|
export const RemotionRoot = () => {
|
||||||
|
const aspect = "9x16" as const; // overridden per-render via --props
|
||||||
|
const {w, h} = ASPECTS[aspect];
|
||||||
|
return (
|
||||||
|
<Composition
|
||||||
|
id="AdTemplate"
|
||||||
|
component={AdTemplate}
|
||||||
|
durationInFrames={theme.durationInSeconds * 30}
|
||||||
|
fps={30}
|
||||||
|
width={w}
|
||||||
|
height={h}
|
||||||
|
defaultProps={{v: defaultVariant, aspect}}
|
||||||
|
// Resolve real dimensions from the incoming aspect prop at render time:
|
||||||
|
calculateMetadata={({props}) => {
|
||||||
|
const a = ASPECTS[(props as any).aspect ?? "9x16"];
|
||||||
|
return {width: a.w, height: a.h};
|
||||||
|
}}
|
||||||
|
/>
|
||||||
|
);
|
||||||
|
};
|
||||||
|
```
|
||||||
|
|
||||||
|
`calculateMetadata` lets a single composition output any aspect from the `aspect` prop — no separate composition per ratio.
|
||||||
|
|
||||||
|
## 5. CSV → typed props, with validation
|
||||||
|
|
||||||
|
The dataset is the input. Parse, validate every row (a bad hex or empty CTA must fail loudly, not render a broken ad), and write one props file per variant.
|
||||||
|
|
||||||
|
```js
|
||||||
|
// csv-to-props.js usage: node csv-to-props.js variants.csv ./props [aspect]
|
||||||
|
const fs = require("fs");
|
||||||
|
const path = require("path");
|
||||||
|
|
||||||
|
const [, , csvPath, outDir, aspect = "9x16"] = process.argv;
|
||||||
|
const REQUIRED = ["id", "hook", "benefit", "proof", "cta", "accent", "bg"];
|
||||||
|
const isHex = (s) => /^#([0-9a-f]{3}|[0-9a-f]{6})$/i.test(s);
|
||||||
|
|
||||||
|
const parseCSV = (text) => {
|
||||||
|
const [head, ...lines] = text.trim().split(/\r?\n/);
|
||||||
|
const cols = head.split(",").map((c) => c.trim());
|
||||||
|
return lines.filter(Boolean).map((line) => {
|
||||||
|
// simple split; wrap fields containing commas in double quotes in the CSV
|
||||||
|
const cells = line.match(/("([^"]|"")*"|[^,]*)/g).filter((_, i, a) => i < a.length - 1);
|
||||||
|
const row = {};
|
||||||
|
cols.forEach((c, i) => (row[c] = (cells[i] ?? "").replace(/^"|"$/g, "").replace(/""/g, '"').trim()));
|
||||||
|
return row;
|
||||||
|
});
|
||||||
|
};
|
||||||
|
|
||||||
|
const rows = parseCSV(fs.readFileSync(csvPath, "utf8"));
|
||||||
|
fs.mkdirSync(outDir, {recursive: true});
|
||||||
|
|
||||||
|
const seen = new Set();
|
||||||
|
let errors = 0;
|
||||||
|
rows.forEach((row, n) => {
|
||||||
|
const where = `row ${n + 2} (${row.id || "no-id"})`;
|
||||||
|
REQUIRED.forEach((k) => { if (!row[k]) { console.error(`✗ ${where}: missing "${k}"`); errors++; } });
|
||||||
|
if (seen.has(row.id)) { console.error(`✗ ${where}: duplicate id`); errors++; }
|
||||||
|
seen.add(row.id);
|
||||||
|
if (row.hook && row.hook.length > 60) console.warn(`⚠ ${where}: hook >60 chars may clip in 9:16`);
|
||||||
|
["accent", "bg"].forEach((k) => { if (row[k] && !isHex(row[k])) { console.error(`✗ ${where}: "${k}" not a hex color`); errors++; } });
|
||||||
|
if (errors) return;
|
||||||
|
fs.writeFileSync(path.join(outDir, `${row.id}.json`), JSON.stringify({v: row, aspect}, null, 2));
|
||||||
|
});
|
||||||
|
|
||||||
|
if (errors) { console.error(`\n${errors} error(s) — no broken ads written.`); process.exit(1); }
|
||||||
|
console.log(`✓ ${rows.length} variant prop files written to ${outDir}`);
|
||||||
|
```
|
||||||
|
|
||||||
|
Example `variants.csv` (one fully message-matched ad per row):
|
||||||
|
|
||||||
|
```csv
|
||||||
|
id,hook,benefit,proof,cta,accent,bg
|
||||||
|
v01_problem,Spending 2 hrs/day on reports?,Auto-build them in one click.,Teams save 11 hrs a week.,Save 2 hours — try free,#4F46E5,#FFFFFF
|
||||||
|
v02_interrupt,Your reporting tool is lying to you.,See the real numbers instantly.,Teams save 11 hrs a week.,See the real numbers — free,#DC2626,#0B0B0F
|
||||||
|
v03_curiosity,Nobody talks about this reporting trick.,One click builds the whole report.,Teams save 11 hrs a week.,Try the trick — free,#059669,#FFFFFF
|
||||||
|
```
|
||||||
|
|
||||||
|
Note the CTA mirrors the hook in every row — that is the message-match discipline encoded into the data.
|
||||||
|
|
||||||
|
## 6. Test-matrix generator — one variable at a time
|
||||||
|
|
||||||
|
A test only teaches something if exactly one field changes. This expands a base variant plus a list of values for ONE field into a CSV, so a hook test or a CTA test stays clean and combinatorial mistakes are impossible.
|
||||||
|
|
||||||
|
```js
|
||||||
|
// make-matrix.js usage: node make-matrix.js > variants.csv
|
||||||
|
const base = {benefit: "Auto-build them in one click.", proof: "Teams save 11 hrs a week.",
|
||||||
|
cta: "Save 2 hours — try free", accent: "#4F46E5", bg: "#FFFFFF"};
|
||||||
|
|
||||||
|
// Vary ONLY this field; everything else is held identical across the test.
|
||||||
|
const FIELD = "hook";
|
||||||
|
const values = [
|
||||||
|
"Spending 2 hrs/day on reports?",
|
||||||
|
"Your reporting tool is lying to you.",
|
||||||
|
"Nobody talks about this reporting trick.",
|
||||||
|
"Cut report time in half this week.",
|
||||||
|
"If you build reports by hand, stop.",
|
||||||
|
];
|
||||||
|
|
||||||
|
const esc = (s) => (/[",]/.test(s) ? `"${s.replace(/"/g, '""')}"` : s);
|
||||||
|
const cols = ["id", "hook", "benefit", "proof", "cta", "accent", "bg"];
|
||||||
|
console.log(cols.join(","));
|
||||||
|
values.forEach((val, i) => {
|
||||||
|
const row = {...base, [FIELD]: val, id: `${FIELD}_${String(i + 1).padStart(2, "0")}`};
|
||||||
|
console.log(cols.map((c) => esc(row[c])).join(","));
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
To run a CTA test next, set `FIELD = "cta"`, paste the *winning* hook into `base.hook`, and list CTA variants. Same one-variable rule, next stage of the funnel.
|
||||||
|
|
||||||
|
## 7. Batch + multi-aspect render
|
||||||
|
|
||||||
|
Render every variant in every aspect a campaign needs. Concurrency keeps large batches fast.
|
||||||
|
|
||||||
|
```bash
|
||||||
|
#!/usr/bin/env bash
|
||||||
|
# render-all.sh one MP4 per (variant × aspect)
|
||||||
|
set -euo pipefail
|
||||||
|
|
||||||
|
node make-matrix.js > variants.csv # 1) build the one-variable test matrix
|
||||||
|
ASPECTS=("9x16" "4x5" "1x1") # placements this campaign needs
|
||||||
|
|
||||||
|
for ar in "${ASPECTS[@]}"; do
|
||||||
|
node csv-to-props.js variants.csv "props/$ar" "$ar" # 2) typed, validated props per aspect
|
||||||
|
for f in "props/$ar"/*.json; do
|
||||||
|
id=$(basename "$f" .json)
|
||||||
|
npx remotion render AdTemplate "out/${id}_${ar}.mp4" \
|
||||||
|
--props="$f" --concurrency=4 --log=error # 3) render
|
||||||
|
done
|
||||||
|
done
|
||||||
|
|
||||||
|
echo "Done. $(ls out/*.mp4 | wc -l) ad variants in ./out"
|
||||||
|
```
|
||||||
|
|
||||||
|
5 hooks × 3 aspects = 15 MP4s from one template and one command. Add a CTA stage and the same template produces the next test wave with zero new component code.
|
||||||
|
|
||||||
|
## Common pitfalls
|
||||||
|
|
||||||
|
- **Two variables changed at once** — the winner is uninterpretable. The matrix generator prevents this; keep using it.
|
||||||
|
- **Hook clips in 9:16** — long hooks overflow; the parser warns past 60 chars. Keep hooks short and high in the frame.
|
||||||
|
- **CTA hidden behind platform UI** — anything in the 9:16 bottom third gets covered by captions and the CTA button. The `bottomSafe` padding reserves that band.
|
||||||
|
- **Drift across variants** — accent/copy live in the data, everything else in `theme`. If a variant looks off-brand, the fix is the theme, not the row.
|
||||||
|
- **Animation flicker in export** — caused by CSS transitions or library timers. Every value must derive from `useCurrentFrame()`.

# Platform Specs & Message-Match Worksheet
|
||||||
|
|
||||||
|
Exact pixel safe zones, durations, aspect ratios, and format limits per placement (2025/2026), plus a worksheet for building message-matched hook→CTA pairs before they go into the CSV. Verify against each platform's current Ads Manager docs before a big spend — placements and safe zones shift.
|
||||||
|
|
||||||
|
## Aspect ratio → placement map
|
||||||
|
|
||||||
|
| Aspect | Resolution | Native placements |
|
||||||
|
|---|---|---|
|
||||||
|
| 9:16 | 1080×1920 | TikTok In-Feed, Instagram/Facebook Reels, Stories, YouTube Shorts |
|
||||||
|
| 4:5 | 1080×1350 | Meta Feed (largest feed real estate, recommended for Feed video) |
|
||||||
|
| 1:1 | 1080×1080 | Meta Feed, broad/automatic placements, X |
|
||||||
|
| 16:9 | 1920×1080 | YouTube in-stream, landscape feed, in-article |
|
||||||
|
|
||||||
|
Master rule: design the hook, product, and CTA inside the **1:1 center square** so a single composition reframes to every aspect by re-centering, not letterboxing. Black bars on a vertical feed read as "ad" and underperform.
|
||||||
|
|
||||||
|
## Safe zones (keep-clear bands)
|
||||||
|
|
||||||
|
Platform UI — captions, CTA chips, usernames, profile icons, progress bars — overlaps the frame. Keep all critical content out of these bands.
|
||||||
|
|
||||||
|
| Aspect / placement | Top keep-clear | Bottom keep-clear | Sides |
|
||||||
|
|---|---|---|---|
|
||||||
|
| 9:16 Reels/Stories (Meta) | ~14% (~270px on 1920h) | ~20–35% (~384–672px) | ~6% (~65px) |
|
||||||
|
| 9:16 TikTok In-Feed | ~130px | ~484px (right-side icon rail + caption) | right ~140px |
|
||||||
|
| 4:5 Meta Feed | ~5% | ~10% (keep CTA above it) | ~5% |
|
||||||
|
| 1:1 / 16:9 | center 90% safe | center 90% safe | center 90% safe |
|
||||||
|
|
||||||
|
The 9:16 bottom third is the single most violated zone — captions, the CTA button, and the handle stack there. The `bottomSafe` padding in `batch-ad-pipeline.md` reserves it.
|
||||||
|
|
||||||
|
## Duration & format limits
|
||||||
|
|
||||||
|
| Placement | Sweet spot | Hard limits | Format |
|
||||||
|
|---|---|---|---|
|
||||||
|
| Meta Feed (4:5/1:1) | 6–15s | up to 240 min, ≤4GB | MP4/MOV, H.264 |
|
||||||
|
| Meta Reels/Stories (9:16) | 8–15s | Reels ≤90s, Stories ≤2 min | MP4/MOV |
|
||||||
|
| TikTok In-Feed (9:16) | 15–30s (TikTok cites 21–34s) | up to 10 min (non-Spark) | MP4/MOV, ≥540×960 |
|
||||||
|
| YouTube in-stream (16:9) | 15–30s | skippable after 5s | MP4 |
|
||||||
|
|
||||||
|
Practical default for performance video: **15–30s, with the hook trigger landing before 2s.** Most ad-account data shows attention falls off a cliff after ~15s, so front-load everything that matters.
|
||||||
|
|
||||||
|
## Hook → CTA message-match worksheet
|
||||||
|
|
||||||
|
Fill one row per ad *before* writing the CSV. The CTA must pay off the exact promise the hook made; if it doesn't, the click is wasted and the test is noisy. Each completed row becomes one record in `variants.csv`.
|
||||||
|
|
||||||
|
| Hook (0–3s promise) | Hook type | Single benefit | Proof point | CTA (pays off the hook) |
|
||||||
|
|---|---|---|---|---|
|
||||||
|
| "Spending 2 hrs/day on reports?" | problem-first | one-click report build | "save 11 hrs/week" | "Save 2 hours — try free" |
|
||||||
|
| "Your reporting tool is lying to you." | pattern interrupt | shows real numbers instantly | "save 11 hrs/week" | "See the real numbers — free" |
|
||||||
|
| "Nobody talks about this reporting trick." | curiosity gap | one click builds it | "save 11 hrs/week" | "Try the trick — free" |
|
||||||
|
| "Cut report time in half this week." | immediate benefit | auto-built reports | "save 11 hrs/week" | "Cut it in half — free" |
|
||||||
|
| "If you build reports by hand, stop." | direct callout | automate it now | "save 11 hrs/week" | "Automate yours — free" |
|
||||||
|
|
||||||
|
Bad pairing to avoid: a "stop wasting 2 hours" hook ending on a generic "Shop now" — the promise and the payoff don't connect, so even a great hook converts poorly.
|
||||||
|
|
||||||
|
## Testing order (which field to vary first)
|
||||||
|
|
||||||
|
Run tests in funnel order; isolate one field per wave using the matrix generator:
|
||||||
|
|
||||||
|
1. **Hook** — biggest lever on CPA; test 5–8 hooks against one identical body.
|
||||||
|
2. **Offer / benefit** — take the winning hook, vary the core promise.
|
||||||
|
3. **CTA** — winning hook + offer, vary the closing action.
|
||||||
|
4. **Format / aspect** — same winning ad, compare placements.
|
||||||
|
|
||||||
|
Budget guide many teams use: ~60% to proven winners, ~30% to variations of winners, ~10% to fresh concepts. Run each test long enough for a real sample (commonly several hundred impressions per variant, ~1 week to smooth daily swings) before declaring a winner.
|
||||||
|
|
||||||
|
## Pre-flight checklist per variant
|
||||||
|
|
||||||
|
- Hook trigger lands before 2s and fits the frame (≤~60 chars in 9:16).
|
||||||
|
- CTA visibly pays off the hook's specific promise.
|
||||||
|
- Critical content inside the center square and outside every keep-clear band.
|
||||||
|
- Duration within the placement's sweet spot.
|
||||||
|
- Exported in every aspect the campaign's placements require.
|
||||||
|
- Exactly one field differs from the other variants in this test wave.
|
||||||
Whitespace-only changes.

# Launch Video
|
||||||
|
|
||||||
|
Make a premium, high-energy 15–60s launch film that stops the scroll and converts. Build the classic arc — hook → tease → reveal → feature montage → end-card CTA — cut to the music, and export for every platform aspect.
|
||||||
|
|
||||||
|
## When to use
|
||||||
|
|
||||||
|
- Product drops, feature announcements, trailers, hype reels (15–60s).
|
||||||
|
- "Sizzle" hero videos for a landing page.
|
||||||
|
- Beat-synced reveals where the brand moment lands on the drop.
|
||||||
|
|
||||||
|
## The arc
|
||||||
|
|
||||||
|
| Beat | Job | Typical share (of 30s) |
|
||||||
|
|---|---|---|
|
||||||
|
| Hook (0–3s) | A striking frame/motion that stops the scroll | 0–3s |
|
||||||
|
| Tease | Hint the product; build curiosity, beat-synced | 3–9s |
|
||||||
|
| Reveal | Product/logo hits on the music drop | 9–13s |
|
||||||
|
| Feature montage | Fast, kinetic, one benefit per shot | 13–25s |
|
||||||
|
| End card | Logo + tagline + CTA, clean hold | 25–30s |
|
||||||
|
|
||||||
|
Scale the same proportions for 15s (tighter) or 60s (longer montage, never a longer hook).
|
||||||
|
|
||||||
|
## Two non-negotiable rules
|
||||||
|
|
||||||
|
1. **Sound design leads picture.** Lock the track first, mark the beats and the drop, then cut visuals to those marks. Never score a finished cut — the reveal lands on the drop, not near it.
|
||||||
|
2. **Quality over quantity.** A few flawless shots beat many mediocre ones. Cut any shot that isn't premium.
|
||||||
|
|
||||||
|
## Beat-synced reveal on the drop
|
||||||
|
|
||||||
|
Find the drop's exact timecode in the audio, then time the reveal so the brand mark snaps to full at that frame, with a micro-overshoot for impact.
|
||||||
|
|
||||||
|
```js
|
||||||
|
import gsap from "gsap";
|
||||||
|
const DROP = 9.0; // seconds, measured from the track
|
||||||
|
const tl = gsap.timeline({ paused: true });
|
||||||
|
// tease builds tension up to the drop
|
||||||
|
tl.to(".tease", { opacity: 1, scale: 1.05, duration: DROP, ease: "power1.in" })
|
||||||
|
// reveal SNAPS on the drop frame
|
||||||
|
.set(".logo", { opacity: 1 }, DROP)
|
||||||
|
.fromTo(".logo", { scale: 1.18 }, { scale: 1.0, duration: .18, ease: "power3.out" }, DROP)
|
||||||
|
.fromTo(".flash", { opacity: .9 }, { opacity: 0, duration: .25 }, DROP); // white hit
|
||||||
|
audio.addEventListener("play", () => tl.play());
|
||||||
|
```
|
||||||
|
|
||||||
|
Cut on transients, not on a fixed grid: the hardest cuts go on kick/snare hits; ramp speed (time-remap) into the drop, then hard-cut out of it.
|
||||||
|
|
||||||
|
## Kinetic feature montage
|
||||||
|
|
||||||
|
One benefit per shot, ~0.6–1.0s each, hard cuts on the beat. Each shot = a bold keyword + a single supporting visual.
|
||||||
|
|
||||||
|
```css
|
||||||
|
.feature { opacity:0; }
|
||||||
|
.feature.in .kw { animation: pop .35s cubic-bezier(.22,1,.36,1) forwards; }
|
||||||
|
.feature.in .word { display:inline-block; }
|
||||||
|
@keyframes pop { from { opacity:0; transform:translateY(24px) } to { opacity:1; transform:none } }
|
||||||
|
```
|
||||||
|
|
||||||
|
```js
|
||||||
|
// drive shots off beat marks measured from the track
|
||||||
|
const beats = [13.0, 13.8, 14.6, 15.4, 16.2]; // seconds
|
||||||
|
beats.forEach((t, i) => scheduleAt(t, () => showFeature(i)));
|
||||||
|
```
|
||||||
|
|
||||||
|
Keep one motion language across the montage (same enter curve, same exit) so speed reads as confidence, not chaos.
|
||||||
|
|
||||||
|
## End card
|
||||||
|
|
||||||
|
Hold the logo + tagline + CTA still and clean for ≥2s. No busy motion competing with the CTA; let the brand settle. Land the brand moment on the strongest remaining beat, then a crisp button/URL.
|
||||||
|
|
||||||
|
## Multi-aspect export
|
||||||
|
|
||||||
|
Compose with a center safe zone so one master crops cleanly to all aspects.
|
||||||
|
|
||||||
|
| Aspect | Use | Resolution | Safe zone |
|
||||||
|
|---|---|---|---|
|
||||||
|
| 16:9 | YouTube, landing hero, X | 1920×1080 | keep key content within center 90% |
|
||||||
|
| 9:16 | Reels, TikTok, Shorts, Stories | 1080×1920 | text within center 80% h; avoid top 12% / bottom 18% (UI) |
|
||||||
|
| 1:1 | Feed posts | 1080×1080 | center square of the 16:9 frame |
|
||||||
|
|
||||||
|
Design the hero/logo/CTA inside the **1:1 center square** so it survives every crop. Render the 16:9 master, then reframe (don't just letterbox) 9:16 and 1:1 from the same project.
|
||||||
|
|
||||||
|
## Output checklist
|
||||||
|
|
||||||
|
- Track locked first; reveal lands exactly on the drop.
|
||||||
|
- Hook earns the first 3 seconds.
|
||||||
|
- Montage: one benefit per shot, hard cuts on beats, consistent motion language.
|
||||||
|
- End card holds ≥2s with one clear CTA.
|
||||||
|
- 16:9 + 9:16 + 1:1 exports, key content in the center safe zone.
|
||||||
|
- Premium-only shots — nothing mediocre survives the cut.
|
||||||
|
|
||||||

> **Packaged helper** (`scripts/`): tile your stills with `scripts/contact-sheet.sh sheet.png f-hook.png f-mid.png f-end.png`, then assert the encode with `scripts/probe-mp4.sh out.mp4 [WxH] [fps]`. See `scripts/README.md`.
|
||||||
|
|
||||||
|
If the launch film is built/rendered in Remotion, treat it as the heavy tier: register a `<Composition>` (+ zod `schema` + `defaultProps`), drive every value off `useCurrentFrame()` — no GSAP timelines / audio-event callbacks / `Date.now()` / `Math.random()` at render time (bake beat + drop timecodes into props). Deliverable = the rendered `out/*.mp4` per aspect (plus the project).
|
||||||
|
|
||||||
|
**Verify loop — render stills → inspect → encode.** Sample the arc, with the **shipped** props (real headline/tagline/CTA), not just `defaultProps`.
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Frame-exact stills across hook → reveal → end-card
|
||||||
|
npx remotion still Launch out/f-hook.png --frame=24 --props=props/launch.json # hook earns first 3s
|
||||||
|
npx remotion still Launch out/f-reveal.png --frame=270 --props=props/launch.json # logo SNAPS on the drop frame
|
||||||
|
npx remotion still Launch out/f-end.png --frame=899 --props=props/launch.json # end card: logo+tagline+CTA, clean hold
|
||||||
|
# inspect each: fidelity (product/logo, tagline, CTA text exact, brand colors right, reveal at the drop frame)
|
||||||
|
# AND artifacts (text overflow, off-canvas, CTA in the 9:16 bottom third, missing font, flash frame stuck on)
|
||||||
|
```
|
||||||
|
|
||||||
|
**Multi-aspect — verify the master in EACH aspect before encoding all of them.** A reframe bug (hero pushed off the safe zone) repeats across every aspect; catch it once.
|
||||||
|
|
||||||
|
```bash
|
||||||
|
for ar in 16x9 9x16 1x1; do # check reveal + end card per aspect
|
||||||
|
npx remotion still Launch "out/reveal-${ar}.png" --frame=270 \
|
||||||
|
--props=props/launch.json --props-merge="{\"aspect\":\"${ar}\"}"
|
||||||
|
done
|
||||||
|
# stills clean in all aspects? → then encode each:
|
||||||
|
for ar in 16x9 9x16 1x1; do
|
||||||
|
npx remotion render Launch "out/launch-${ar}.mp4" --props=props/launch.json --props-merge="{\"aspect\":\"${ar}\"}"
|
||||||
|
done
|
||||||
|
npx remotion render Launch out/demo.gif --codec=gif --props=props/launch.json # README demo
|
||||||
|
```
|
||||||
|
|
||||||
|
**Before you finish:**
|
||||||
|
1. `npx remotion still` renders cleanly at hook / reveal / end card — no errors, no missing fonts/assets.
|
||||||
|
2. Logo/tagline/CTA text exact, brand colors right; reveal lands on the drop frame; key content inside the center safe zone, clear of the 9:16 bottom third.
|
||||||
|
3. Frame-driven only — no GSAP/audio-callback timing, `Date.now()`, or `Math.random()` (beats/drop baked into props).
|
||||||
|
4. Shipped props render correctly (not just `defaultProps`); the end card holds ≥2s with one CTA.
|
||||||
|
5. Master verified in 16:9 + 9:16 + 1:1 before encoding; MP4s play; (optional) GIF for the README.

# Launch Video Structure — Cookbook
|
||||||
|
|
||||||
|
Shot-by-shot template, beat-sync timing, montage recipes, and multi-aspect maps for a premium 15–60s launch film.
|
||||||
|
|
||||||
|
## Sound-design-leads-picture workflow
|
||||||
|
|
||||||
|
1. **Pick/commission the track first.** The track defines the film's length and energy.
|
||||||
|
2. **Mark the structure in the audio**: intro, build, the **drop** (the single biggest moment), and the kick/snare transients through the montage. Note exact timecodes.
|
||||||
|
3. **Map beats → cuts.** Hard cuts land on transients; the reveal lands on the drop frame.
|
||||||
|
4. **Build picture to the marks.** Never finish a cut and then look for music. Score-first guarantees the reveal hits.
|
||||||
|
5. **Mix last**: add risers into the drop, an impact/whoosh on the reveal, and let the end-card breathe (drop music low, or a clean tag).
|
||||||
|
|
||||||
|
## Shot-by-shot template — 30s film (scalable)
|
||||||
|
|
||||||
|
```
|
||||||
|
00:00–00:03 HOOK
|
||||||
|
Visual : single striking frame — extreme close detail / impossible motion
|
||||||
|
Motion : slow push-in or a fast whip that resolves; NO logo yet
|
||||||
|
Audio : sub-bass swell begins, sparse
|
||||||
|
Cut : on first audible beat at ~03s
|
||||||
|
|
||||||
|
00:03–00:09 TEASE
|
||||||
|
Visual : fragments/silhouettes of the product, never the full thing
|
||||||
|
Motion : light leaks, partial reveals, parallax; tension rising
|
||||||
|
Audio : riser building toward the drop
|
||||||
|
Cut : quick cuts accelerating into the drop
|
||||||
|
|
||||||
|
00:09–00:13 REVEAL ← THE DROP at 00:09
|
||||||
|
Visual : product/logo SNAPS to full on the drop frame
|
||||||
|
Motion : scale 1.18→1.0 over 0.18s + white flash-out; settle clean
|
||||||
|
Audio : drop hits + impact stinger on the exact frame
|
||||||
|
Hold : let it sit ~1.2s before moving
|
||||||
|
|
||||||
|
00:13–00:25 FEATURE MONTAGE
|
||||||
|
Visual : one benefit per shot, ~0.6–1.0s each (≈8–10 shots)
|
||||||
|
Motion : bold keyword pop + one supporting visual; consistent enter/exit
|
||||||
|
Audio : hard cuts on kick/snare; energy sustained
|
||||||
|
Pattern: KEYWORD + UI/product moment, repeat with rhythm
|
||||||
|
|
||||||
|
00:25–00:30 END CARD
|
||||||
|
Visual : logo + tagline + CTA, centered, still
|
||||||
|
Motion : minimal — a soft settle, then hold ≥2s
|
||||||
|
Audio : music resolves; clean sonic tag
|
||||||
|
CTA : one action (URL or button), nothing competing
|
||||||
|
```
|
||||||
|
|
||||||
|
### Re-proportioning
|
||||||
|
|
||||||
|
- **15s**: Hook 0–2s · Tease 2–5s · Reveal 5–7s · Montage 7–12s (4–5 shots) · End card 12–15s.
|
||||||
|
- **60s**: same hook (still ≤3s) · longer tease and a richer montage (14–16 shots, grouped in waves) · end card ≥3s.
|
||||||
|
|
||||||
|
The hook never gets longer — only the montage scales.
|
||||||
|
|
||||||
|
## Beat-synced reveal (timing detail)
|
||||||
|
|
||||||
|
```js
|
||||||
|
import gsap from "gsap";
|
||||||
|
const DROP = 9.0; // measured drop timecode (s)
|
||||||
|
const tl = gsap.timeline({ paused: true });
|
||||||
|
|
||||||
|
// build tension toward the drop
|
||||||
|
tl.fromTo(".tease", { scale: 1.0, opacity: .6 },
|
||||||
|
{ scale: 1.08, opacity: 1, duration: DROP, ease: "power1.in" });
|
||||||
|
|
||||||
|
// REVEAL exactly on the drop
|
||||||
|
tl.set(".logo", { opacity: 1 }, DROP);
|
||||||
|
tl.fromTo(".logo", { scale: 1.18 }, { scale: 1.0, duration: .18, ease: "power3.out" }, DROP);
|
||||||
|
tl.fromTo(".flash", { opacity: .9 }, { opacity: 0, duration: .25, ease: "power2.out" }, DROP);
|
||||||
|
tl.to(".tease", { opacity: 0, duration: .12 }, DROP);
|
||||||
|
|
||||||
|
// hold the reveal
|
||||||
|
tl.to(".logo", { scale: 1.0, duration: 1.2 }); // dwell
|
||||||
|
|
||||||
|
audio.addEventListener("play", () => tl.play());
|
||||||
|
```
|
||||||
|
|
||||||
|
Speed-ramp into the drop (Remotion time-remap idea): play the last ~0.5s of the tease faster, then hard-cut to the reveal on the drop frame for a snap.
|
||||||
|
|
||||||
|
## Kinetic montage shot recipe
|
||||||
|
|
||||||
|
Each shot: a bold keyword + one product/UI visual, ~0.6–1.0s, hard cut on the beat.
|
||||||
|
|
||||||
|
```css
|
||||||
|
.feature { position:absolute; inset:0; opacity:0; }
|
||||||
|
.feature.in { opacity:1; }
|
||||||
|
.feature .word { display:inline-block; opacity:0; transform:translateY(26px); }
|
||||||
|
.feature.in .word { animation: pop .32s cubic-bezier(.22,1,.36,1) forwards; }
|
||||||
|
.feature.in .word:nth-child(2){ animation-delay:.04s }
|
||||||
|
.feature.in .word:nth-child(3){ animation-delay:.08s }
|
||||||
|
@keyframes pop { to { opacity:1; transform:none; } }
|
||||||
|
```
|
||||||
|
|
||||||
|
```js
|
||||||
|
// schedule shots on measured beat marks
|
||||||
|
const beats = [13.0, 13.8, 14.6, 15.4, 16.2, 17.0, 17.8, 18.6]; // seconds
|
||||||
|
let i = 0;
|
||||||
|
function loop(now){
|
||||||
|
const t = (now - start) / 1000;
|
||||||
|
if (i < beats.length && t >= beats[i]) { showFeature(i); i++; }
|
||||||
|
if (i < beats.length) requestAnimationFrame(loop);
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
Montage discipline: keep ONE enter curve and ONE exit across all shots; vary content, never grammar. Alternate visual rhythm (full-frame ↔ detail) but keep cut cadence locked to the beat.
|
||||||
|
|
||||||
|
## Multi-aspect safe-area maps
|
||||||
|
|
||||||
|
Compose so a single master reframes to every aspect. Place hero/logo/CTA inside the smallest common safe zone — the 1:1 center square.
|
||||||
|
|
||||||
|
```
|
||||||
|
16:9 1920×1080
|
||||||
|
Safe: center 90% (96px H / 54px V margins)
|
||||||
|
Use : YouTube, landing hero, X timeline
|
||||||
|
|
||||||
|
9:16 1080×1920
|
||||||
|
Safe: text within center 80% height
|
||||||
|
Avoid: top 12% (status/clock area), bottom 18% (caption + UI buttons)
|
||||||
|
Use : Reels, TikTok, Shorts, Stories
|
||||||
|
|
||||||
|
1:1 1080×1080
|
||||||
|
Safe: this square == the design anchor; put logo/CTA here
|
||||||
|
Use : feed posts
|
||||||
|
```
|
||||||
|
|
||||||
|
Export workflow:
|
||||||
|
|
||||||
|
1. Build the 16:9 master with all key content inside the 1:1 center square.
|
||||||
|
2. For 9:16, **reframe** (pan/scale per shot to keep the subject centered) — do not letterbox.
|
||||||
|
3. For 1:1, crop the center square; verify text isn't clipped.
|
||||||
|
4. Re-check captions/CTA against each platform's UI overlay zones before export.
|
||||||
|
|
||||||
|
## Final QA checklist
|
||||||
|
|
||||||
|
- [ ] Reveal lands on the exact drop frame, with overshoot + flash.
|
||||||
|
- [ ] Hook holds attention in the first 3s without showing the product.
|
||||||
|
- [ ] Every montage shot is one benefit, premium quality, on a beat.
|
||||||
|
- [ ] End card holds ≥2s, single CTA, nothing competing.
|
||||||
|
- [ ] 16:9 / 9:16 / 1:1 each pass safe-area and caption checks.
|
||||||
|
- [ ] Audio mixed: riser → impact on drop → clean tag on end card.

# Testimonial Video
|
||||||
|
|
||||||
|
Animate a written quote, review, or testimonial into a short, trustworthy social-proof clip. The craft is typographic, not flashy: a clean quote card where the words land in reading order, the key phrase gets emphasis exactly when it should, the stars fill to the real score, and the author signs off. One card design, driven by props, becomes a video for every review on the list.
|
||||||
|
|
||||||
|
## When to use
|
||||||
|
|
||||||
|
- Customer review → a 6–12s vertical/feed clip (the headline use case).
|
||||||
|
- A pull-quote or testimonial graphic with author name, role, avatar, company.
|
||||||
|
- An animated star rating (including half/fractional scores like 4.5).
|
||||||
|
- A batch: a list/CSV of reviews → one video each, same template.
|
||||||
|
|
||||||
|
Do **not** reach here for sale/discount promos or generic ad creative — this skill is strictly the quote / social-proof angle.
|
||||||
|
|
||||||
|
## The one rule: trust before motion
|
||||||
|
|
||||||
|
A testimonial earns its job by feeling *real*, not produced. Restraint reads as credibility; over-animation reads as an ad people skip.
|
||||||
|
|
||||||
|
1. **Reveal in reading order.** The eye must finish a line before the next arrives. Stagger lines (or clauses), never all words at once, and never reorder for visual flair.
|
||||||
|
2. **Quote the words exactly.** Do not paraphrase, trim mid-sentence, or invent a rating. If you emphasize a phrase, it must be the customer's phrase.
|
||||||
|
3. **The author is the proof.** A quote with no attributable human is just a slogan. Name + role + company (and avatar if real) is non-negotiable.
|
||||||
|
|
||||||
|
## The anatomy of a quote card
|
||||||
|
|
||||||
|
| Element | Job | Timing |
|
||||||
|
|---|---|---|
|
||||||
|
| Quote mark motif | Signals "this is a quote" before words read | Frame 0, scales/fades in first |
|
||||||
|
| Quote body | The testimonial, revealed line-by-line | Staggered, ~6–10 frames apart |
|
||||||
|
| Emphasis span | The one phrase that sells | Lands *after* its line settles |
|
||||||
|
| Star rating | The score, filled to the real value | Fills left→right after the quote |
|
||||||
|
| Author block | Name / role / company / avatar | Signs off last, slides up |
|
||||||
|
|
||||||
|
Build in that order; reveal in that order. The viewer reads the quote, believes it, sees the score, then learns who said it.
|
||||||
|
|
||||||
|
## Staggered line reveal
|
||||||
|
|
||||||
|
Split the quote into lines (or clauses), then offset each one's entrance. In Remotion, drive every line off `useCurrentFrame()` so it renders deterministically — never a CSS transition or a JS timer, which desync from the frame renderer.
|
||||||
|
|
||||||
|
```jsx
|
||||||
|
import { useCurrentFrame, spring, useVideoConfig } from "remotion";
|
||||||
|
|
||||||
|
const QuoteBody = ({ lines, startAt = 8, stagger = 6 }) => {
|
||||||
|
const frame = useCurrentFrame();
|
||||||
|
const { fps } = useVideoConfig();
|
||||||
|
return (
|
||||||
|
<blockquote>
|
||||||
|
{lines.map((line, i) => {
|
||||||
|
const enter = spring({ frame: frame - startAt - i * stagger, fps,
|
||||||
|
config: { damping: 200 } }); // 0→1, no overshoot
|
||||||
|
return (
|
||||||
|
<span key={i} style={{ display: "block",
|
||||||
|
opacity: enter,
|
||||||
|
transform: `translateY(${(1 - enter) * 14}px)` }}>
|
||||||
|
{line}
|
||||||
|
</span>
|
||||||
|
);
|
||||||
|
})}
|
||||||
|
</blockquote>
|
||||||
|
);
|
||||||
|
};
|
||||||
|
```
|
||||||
|
|
||||||
|
Keep one motion language: same easing, same 14px rise, every line. Speed reads as confidence only when it's consistent. See `references/quote-card.md` for the full composition.
|
||||||
|
|
||||||
|
## Kinetic emphasis on the key phrase
|
||||||
|
|
||||||
|
Pick the single phrase that carries the testimonial ("saved us 10 hours a week") and let it arrive *after* its line has settled — a highlight sweep, a weight shift, or a color pop. Emphasis competing with the reveal cancels both.
|
||||||
|
|
||||||
|
```jsx
|
||||||
|
const sweep = interpolate(frame, [hlStart, hlStart + 10], [0, 100],
|
||||||
|
{ extrapolateLeft: "clamp", extrapolateRight: "clamp" });
|
||||||
|
// a highlighter wiping in behind the phrase, left→right
|
||||||
|
<mark style={{ background:
|
||||||
|
`linear-gradient(90deg, var(--accent) ${sweep}%, transparent ${sweep}%)`,
|
||||||
|
color: "inherit", padding: "0 .08em" }}>{phrase}</mark>
|
||||||
|
```
|
||||||
|
|
||||||
|
Emphasize at most one span per quote. Two highlights is no highlight.
|
||||||
|
|
||||||
|
## Animated star rating (fractional)
|
||||||
|
|
||||||
|
Render the real score, including halves. Use one full row of star glyphs as a mask, then wipe a filled layer to `rating / max` width — this handles 4.5 as cleanly as 5.0, with no half-star sprite.
|
||||||
|
|
||||||
|
```jsx
|
||||||
|
const StarRating = ({ rating, max = 5, fillStart = 30, fillDur = 14 }) => {
|
||||||
|
const frame = useCurrentFrame();
|
||||||
|
const target = (rating / max) * 100;
|
||||||
|
const w = interpolate(frame, [fillStart, fillStart + fillDur], [0, target],
|
||||||
|
{ extrapolateLeft: "clamp", extrapolateRight: "clamp" });
|
||||||
|
return (
|
||||||
|
<div className="stars" role="img" aria-label={`${rating} out of ${max} stars`}>
|
||||||
|
<div className="track">★★★★★</div>
|
||||||
|
<div className="fill" style={{ width: `${w}%` }}>★★★★★</div>
|
||||||
|
</div>
|
||||||
|
);
|
||||||
|
};
|
||||||
|
```
|
||||||
|
|
||||||
|
```css
|
||||||
|
.stars { position: relative; display: inline-block; font-size: 40px; letter-spacing: 4px; }
|
||||||
|
.track { color: rgba(255,255,255,.22); }
|
||||||
|
.fill { position: absolute; inset: 0; overflow: hidden; white-space: nowrap;
|
||||||
|
color: var(--accent); } /* clipped by width → fractional fill */
|
||||||
|
```
|
||||||
|
|
||||||
|
Fill left→right after the quote reads. Never animate stars before the words — the score must feel earned, not pre-loaded. Always set `aria-label` to the real value.
|
||||||
|
|
||||||
|
## The author block
|
||||||
|
|
||||||
|
Sign off last. The block slides up under the stars and holds still — stillness is what makes attribution read as fact.
|
||||||
|
|
||||||
|
```jsx
|
||||||
|
<figcaption className="author">
|
||||||
|
{avatar && <img src={avatar} alt="" className="avatar" />}
|
||||||
|
<div>
|
||||||
|
<span className="name">{name}</span>
|
||||||
|
<span className="role">{role}{company && `, ${company}`}</span>
|
||||||
|
</div>
|
||||||
|
</figcaption>
|
||||||
|
```
|
||||||
|
|
||||||
|
Use a real avatar or none — a generic placeholder face actively destroys trust. Name is the loudest line in the block; role/company is secondary weight.
|
||||||
|
|
||||||
|
## Template × reviews — one video per quote
|
||||||
|
|
||||||
|
The payoff: make every field a prop, hardcode nothing, then render once per review.
|
||||||
|
|
||||||
|
```jsx
|
||||||
|
export const Testimonial = ({ quote, highlight, rating, name, role, company, avatar }) => { /* … */ };
|
||||||
|
```
|
||||||
|
```bash
|
||||||
|
for f in reviews/*.json; do
|
||||||
|
npx remotion render Testimonial "out/$(basename "$f" .json).mp4" --props="$f"
|
||||||
|
done
|
||||||
|
```
|
||||||
|
|
||||||
|
Keep colors/fonts/quote-mark/layout in one theme object so 50 testimonials stay brand-locked and only the words and score change. See `references/batch-and-typography.md` for the review schema, CSV→props parsing, quote-typography craft (smart quotes, hanging punctuation, line-splitting, orphans), and the batch script.

- Lines reveal in reading order; one consistent enter motion, ~6–10 frame stagger.
|
||||||
|
- The quote is verbatim; exactly one emphasized span, landing after its line settles.
|
||||||
|
- Stars fill to the *real* score (halves supported) after the quote, with a correct `aria-label`.
|
||||||
|
- Author block (name + role + company, real avatar or none) signs off last and holds still.
|
||||||
|
- Every animated value derives from `useCurrentFrame()` — no CSS/JS timers.
|
||||||
|
- Every field is a prop; one template renders every review in the folder.
|
||||||
|
|
||||||
|
## Deliver & verify (rendered stills → MP4)
|
||||||
|
|
||||||
|
> **Packaged helper** (`scripts/`): tile your stills with `scripts/contact-sheet.sh sheet.png f-hook.png f-mid.png f-end.png`, then assert the encode with `scripts/probe-mp4.sh out.mp4 [WxH] [fps]`. See `scripts/README.md`.
|
||||||
|
|
||||||
|
**Output contract:**
|
||||||
|
- A Remotion `Testimonial` registered as `<Composition>` (+ zod `schema` + `defaultProps`), every value frame-driven (no CSS transitions / JS timers / `Date.now()` / `Math.random()`).
|
||||||
|
- Deliverable = the rendered `out/*.mp4` per review per aspect (plus the project + review data, so the user re-renders on new quotes).
|
||||||
|
|
||||||
|
**Verify loop — render stills → inspect → encode.** Cheap PNGs first; render with the **shipped** review's props, not just `defaultProps`.
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Frame-exact stills across the reveal order: quote → stars → author
|
||||||
|
npx remotion still Testimonial out/f-quote.png --frame=30 --props=reviews/r1.json # lines in reading order, emphasis span
|
||||||
|
npx remotion still Testimonial out/f-stars.png --frame=48 --props=reviews/r1.json # stars filled to the REAL score (e.g. 4.5)
|
||||||
|
npx remotion still Testimonial out/f-author.png --frame=215 --props=reviews/r1.json # author block signed off, holding still
|
||||||
|
# inspect each: fidelity (quote VERBATIM, exactly one emphasized span, star fill matches rating, name/role/company exact)
|
||||||
|
# AND artifacts (text overflow/orphans, off-canvas, author in the 9:16 bottom third, missing font, broken avatar)
|
||||||
|
```
|
||||||
|
|
||||||
|
**Multi-aspect / batch — verify one review in EACH target aspect before batch-rendering the list.** A layout bug (overflowing quote, clipped author) repeats across every review × aspect; catch it once.
|
||||||
|
|
||||||
|
```bash
|
||||||
|
for ar in 9x16 1x1 16x9; do # one representative review, every aspect
|
||||||
|
npx remotion still Testimonial "out/r1-${ar}.png" --frame=215 \
|
||||||
|
--props=reviews/r1.json --props-merge="{\"aspect\":\"${ar}\"}"
|
||||||
|
done
|
||||||
|
# stills clean in all aspects? → then batch-render the list:
|
||||||
|
for f in reviews/*.json; do id=$(basename "$f" .json); for ar in 9x16 1x1 16x9; do
|
||||||
|
npx remotion render Testimonial "out/${id}-${ar}.mp4" --props="$f" --props-merge="{\"aspect\":\"${ar}\"}"
|
||||||
|
done; done
|
||||||
|
npx remotion render Testimonial out/demo.gif --codec=gif --props=reviews/r1.json # README demo
|
||||||
|
```
|
||||||
|
|
||||||
|
**Before you finish:**
|
||||||
|
1. `npx remotion still` renders cleanly at quote / stars / author — no errors, no missing fonts/avatar.
|
||||||
|
2. Quote is verbatim with one emphasized span; stars fill to the real score; name/role/company exact and inside the safe zone (clear of the 9:16 bottom third).
|
||||||
|
3. Frame-driven only — no CSS/JS timers, `Date.now()`, or `Math.random()`.
|
||||||
|
4. Shipped review's props render correctly (not just `defaultProps`); `aria-label` carries the real rating.
|
||||||
|
5. One review verified in 9:16 + 1:1 + 16:9 before the batch; MP4s play; (optional) GIF for the README.

# Batch & Typography
|
||||||
|
|
||||||
|
How to feed many reviews into one card design, plus the quote-typography craft that separates a credible testimonial from a sloppy one.
|
||||||
|
|
||||||
|
## Review prop schema
|
||||||
|
|
||||||
|
One object per testimonial. Keep it flat so a CSV row maps to it directly.
|
||||||
|
|
||||||
|
```ts
|
||||||
|
type Review = {
|
||||||
|
quote: string; // verbatim — never paraphrased or trimmed mid-sentence
|
||||||
|
highlight?: string; // EXACT substring of `quote`; one phrase only
|
||||||
|
rating: number; // 0–max, halves allowed (4.5)
|
||||||
|
max?: number; // default 5
|
||||||
|
name: string; // required — a quote with no name is not social proof
|
||||||
|
role?: string;
|
||||||
|
company?: string;
|
||||||
|
avatar?: string; // real photo URL, or omit (never a stock face)
|
||||||
|
};
|
||||||
|
```
|
||||||
|
|
||||||
|
### Validation (fail loud, before rendering 50 videos)
|
||||||
|
|
||||||
|
```ts
|
||||||
|
function validate(r: Review): string[] {
|
||||||
|
const errs: string[] = [];
|
||||||
|
if (!r.quote?.trim()) errs.push("quote is empty");
|
||||||
|
if (!r.name?.trim()) errs.push("name is required (no anonymous testimonials)");
|
||||||
|
const max = r.max ?? 5;
|
||||||
|
if (r.rating < 0 || r.rating > max) errs.push(`rating ${r.rating} out of 0–${max}`);
|
||||||
|
if (r.highlight && !r.quote.includes(r.highlight))
|
||||||
|
errs.push(`highlight "${r.highlight}" is not a substring of the quote`);
|
||||||
|
return errs;
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
The `highlight ⊂ quote` check is the important one: it guarantees you only ever emphasize words the customer actually wrote. If the highlight isn't an exact substring, the emphasis silently disappears in the card — so block the render instead.
|
||||||
|
|
||||||
|
## CSV → props
|
||||||
|
|
||||||
|
Reviews usually arrive as a spreadsheet export. Map columns to the schema and coerce the rating.
|
||||||
|
|
||||||
|
```js
|
||||||
|
import { parse } from "csv-parse/sync";
|
||||||
|
import { readFileSync, writeFileSync, mkdirSync } from "node:fs";
|
||||||
|
|
||||||
|
// CSV columns: quote,highlight,rating,name,role,company,avatar
|
||||||
|
const rows = parse(readFileSync("reviews.csv"), { columns: true, trim: true });
|
||||||
|
mkdirSync("reviews", { recursive: true });
|
||||||
|
|
||||||
|
rows.forEach((row, i) => {
|
||||||
|
const r = {
|
||||||
|
quote: row.quote,
|
||||||
|
highlight: row.highlight || undefined,
|
||||||
|
rating: Number(row.rating),
|
||||||
|
name: row.name,
|
||||||
|
role: row.role || undefined,
|
||||||
|
company: row.company || undefined,
|
||||||
|
avatar: row.avatar || undefined,
|
||||||
|
};
|
||||||
|
const errs = validate(r);
|
||||||
|
if (errs.length) { console.error(`Row ${i + 1} (${r.name}):`, errs); process.exit(1); }
|
||||||
|
writeFileSync(`reviews/${String(i).padStart(3, "0")}-${slug(r.name)}.json`,
|
||||||
|
JSON.stringify(r, null, 2));
|
||||||
|
});
|
||||||
|
|
||||||
|
const slug = (s) => s.toLowerCase().replace(/[^a-z0-9]+/g, "-").replace(/^-|-$/g, "");
|
||||||
|
```
|
||||||
|
|
||||||
|
## Batch render — one video per review
|
||||||
|
|
||||||
|
```bash
|
||||||
|
mkdir -p out
|
||||||
|
for f in reviews/*.json; do
|
||||||
|
name=$(basename "$f" .json)
|
||||||
|
npx remotion render Testimonial "out/$name.mp4" --props="$f"
|
||||||
|
done
|
||||||
|
```
|
||||||
|
|
||||||
|
Everything visual lives in the single `theme` object in the composition (colors, fonts, quote-mark glyph, spacing). Because only the props change per render, 50 testimonials stay pixel-for-pixel brand-locked while the words and score vary. To re-theme the whole set, edit one object and re-run the loop.
|
||||||
|
|
||||||
|
For multi-aspect (9:16 feed + 1:1 post + 16:9 site), register the composition at each size with a shared center-safe layout and loop over both `reviews/*.json` and the aspect list.
|
||||||
|
|
||||||
|
## Quote typography craft
|
||||||
|
|
||||||
|
Motion is the easy part; legible, well-set type is what makes the quote trustworthy.
|
||||||
|
|
||||||
|
### Smart quotes, always
|
||||||
|
|
||||||
|
Straight quotes (`"`) read as un-proofed. Convert to typographic quotes before rendering.
|
||||||
|
|
||||||
|
```js
|
||||||
|
const smarten = (s) => s
|
||||||
|
.replace(/(^|[\s([{])"/g, "$1“").replace(/"/g, "”") // “ ”
|
||||||
|
.replace(/(^|[\s([{])'/g, "$1‘").replace(/'/g, "’") // ‘ ’
|
||||||
|
.replace(/--/g, "—"); // em dash
|
||||||
|
```
|
||||||
|
|
||||||
|
### Hanging quotation marks
|
||||||
|
|
||||||
|
A leading quote glyph indents the first line and breaks the flush-left edge. Hang it into the margin so the text block stays optically aligned — the gold standard for set quotes.
|
||||||
|
|
||||||
|
```css
|
||||||
|
blockquote { hanging-punctuation: first; } /* Safari/WebKit */
|
||||||
|
/* Cross-engine fallback: pull the opening mark left by its own width */
|
||||||
|
blockquote::before { content: "\201C"; margin-left: -0.55em; color: var(--muted); }
|
||||||
|
```
|
||||||
|
|
||||||
|
When the card uses a large decorative quote mark (as in `quote-card.md`), drop the inline opening glyph so the mark isn't doubled.
|
||||||
|
|
||||||
|
### Splitting into lines / clauses
|
||||||
|
|
||||||
|
Reveal in reading order means splitting on meaning, not on a fixed character count. Prefer clause boundaries (`. ! ? , ; —`), then pack to a comfortable measure (~32–40 chars at card size). The `toLines` helper in `quote-card.md` does exactly this. Never split a short quote into one-word-per-line — that reads as a ransom note, not a testimonial.
|
||||||
|
|
||||||
|
### Orphans & widows
|
||||||
|
|
||||||
|
A single dangling word on the last line looks broken. Bind the last two words with a non-breaking space so they wrap together.
|
||||||
|
|
||||||
|
```js
|
||||||
|
const noOrphan = (s) => s.replace(/ ([^ ]+)\s*$/, " $1");
|
||||||
|
```
|
||||||
|
|
||||||
|
### Legibility in motion
|
||||||
|
|
||||||
|
- Use a font that stays readable while moving — avoid thin weights and tight tracking; a serif or a humanist sans at 500–600 weight holds up best on a rising line.
|
||||||
|
- Animate **opacity + a small translate** only. Blur, rotation, and scale on body text hurt readability mid-reveal.
|
||||||
|
- Contrast: body text ≥ 4.5:1 against the card; the highlight accent should pass against both the card and the ink it sits behind.
|
||||||
|
- One emphasized span per quote. A second highlight halves the weight of the first.
|
||||||
|
|
||||||
|
## Star-rating accessibility & correctness
|
||||||
|
|
||||||
|
- The visual stars are decorative; expose the value to assistive tech with `role="img"` and `aria-label="4.5 out of 5 stars"` on the container (already in `quote-card.md`).
|
||||||
|
- For fractional scores, the width-clip method (`rating / max * 100%`) is exact for any decimal — no rounding to the nearest half-star, so 4.3 renders as 4.3.
|
||||||
|
- Never animate the stars before the quote is read, and never show more filled stars than the data supports. A faked rating is the fastest way to lose the trust the testimonial was meant to build.
|
||||||
|
- If a review has no rating, omit the star row entirely rather than defaulting to 5 — an invented score is worse than none.
|
||||||
|
|
||||||
|
## Pacing notes
|
||||||
|
|
||||||
|
- Hold the finished card still for the back half of the clip (≥3s) so it's screenshot-able and re-shareable — shares are the whole point of social proof.
|
||||||
|
- For a sequence of testimonials in one video, give each card a full read (~3–4s) and hard-cut between them; cross-dissolving quotes makes both unreadable.

# Quote Card — complete runnable component
|
||||||
|
|
||||||
|
A full testimonial card you can drop into a Remotion project, plus a zero-dependency HTML/CSS variant for non-Remotion pipelines. Both reveal in reading order, emphasize one phrase, fill stars to the real score, and sign off with the author.
|
||||||
|
|
||||||
|
## Timing map (9:16, 30fps, ~10s)
|
||||||
|
|
||||||
|
| Frame | Beat |
|
||||||
|
|---|---|
|
||||||
|
| 0–8 | Quote mark scales in; card settles |
|
||||||
|
| 8–48 | Quote body, line-by-line (8 + i×6) |
|
||||||
|
| 44–54 | Key-phrase highlight sweep (after its line settles) |
|
||||||
|
| 56–70 | Stars fill left→right to `rating/max` |
|
||||||
|
| 72–88 | Author block slides up, holds |
|
||||||
|
| 88–300 | Everything holds still (screenshot-able) |
|
||||||
|
|
||||||
|
The card holds motionless for the back half — stillness is what makes a testimonial read as a fact rather than an ad.

Register it with a duration long enough for the back-half hold:
|
||||||
|
|
||||||
|
```tsx
|
||||||
|
<Composition id="Testimonial" component={Testimonial}
|
||||||
|
durationInFrames={300} fps={30} width={1080} height={1920}
|
||||||
|
defaultProps={{
|
||||||
|
quote: "We shipped in days, not months. Onboarding saved us 10 hours a week.",
|
||||||
|
highlight: "saved us 10 hours a week",
|
||||||
|
rating: 4.5, name: "Dana Reyes", role: "Head of Ops", company: "Northwind",
|
||||||
|
}} />
|
||||||
|
```
|
||||||
|
|
||||||
|
## Why these choices
|
||||||
|
|
||||||
|
- **`spring` with `damping: 200`** gives a clean rise with no overshoot — testimonials should feel composed, not bouncy. The quote mark uses lighter damping (14) for a touch of life on the one decorative element.
|
||||||
|
- **Highlight as a gradient `<mark>`** wipes a real highlighter behind the phrase without a second element or a mask, and survives line wraps via `box-decoration-break: clone`.
|
||||||
|
- **Stars as two stacked glyph rows clipped by width** render any fractional score (4.5, 4.3) with no half-star asset, and the filled row inherits the brand accent.
|
||||||
|
- **Author after stars** matches reading psychology: claim → proof → who. Reordering weakens trust.
|
||||||
|
|
||||||
|
## Zero-dependency HTML/CSS variant
|
||||||
|
|
||||||
|
For pipelines that capture a headless-browser timeline (or just a web embed). Animations are CSS `@keyframes` with per-line `animation-delay`; if rendering frame-exact video, prefer the Remotion version above so frames stay deterministic.
|
||||||
|
|
||||||
|
```html
|
||||||
|
<figure class="card" style="--accent:#FFC24B; --rating:4.5; --max:5">
|
||||||
|
<div class="qmark" aria-hidden="true">“</div>
|
||||||
|
<blockquote>
|
||||||
|
<span style="--i:0">We shipped in days, not months.</span>
|
||||||
|
<span style="--i:1">Onboarding <mark>saved us 10 hours a week.</mark></span>
|
||||||
|
</blockquote>
|
||||||
|
<div class="stars" role="img" aria-label="4.5 out of 5 stars">
|
||||||
|

|
||||||
|
figcaption b { font-size:38px; } figcaption small { display:block; font-size:30px;
|
||||||
|
color:rgba(245,247,250,.55); }
|
||||||
|
@keyframes pop { from { opacity:0; transform:scale(.7) } to { opacity:1; transform:none } }
|
||||||
|
@keyframes rise { from { opacity:0; transform:translateY(14px) } to { opacity:1; transform:none } }
|
||||||
|
```
|
||||||
|
|
||||||
|
The CSS `mark` sweep uses `background-size` (animatable) rather than a gradient color-stop, since color-stop percentages don't animate in CSS. The star `--rating/--max` math is the same fractional fill as the Remotion version.

This skill is part of an open motion-graphics collection from iart.ai — the AI motion agent that turns data, scripts, and designs into editable motion graphics (Remotion → MP4). If you'd rather not hand-build this, iart.ai can turn a list of reviews/quotes into testimonial videos, swap text, and re-export. → [iart.ai](https://iart.ai/?utm_source=github&utm_medium=reference&utm_campaign=ad-video-skills&utm_content=ref_footer&utm_term=testimonial-video)
