Remotion Ads

Create professional video ads and explainer videos with Remotion, ElevenLabs voiceover, and animated captions.

Setup

1. Copy references/brand-config-template.md → references/brand-config.md
2. Fill in brand colors, fonts, voice, caption styling, and content rules
3. Create pronunciation dictionary from assets/dictionaries/template.pls

See references/setup.md for dependencies and folder structure.

Supported Formats

See references/formats.md for safe zones and crop specs. See references/ohneis-style.md for beat-driven cinematic reel template. See references/website-videos.md for 16:9 long-form format.

Workflow

From scratch

# 1. Write scene JSON
# 2. Generate voiceover with word timestamps
node scripts/generate.js \
  --scenes scenes.json \
  --with-timestamps \
  --dictionary your-brand \
  --output-dir public/audio/ad-example/

# 3. Create Remotion composition using actualDuration from info.json
# 4. Render
npx remotion render AdExample out/ad-example.mp4 --codec=h264 --crf=18

From a URL (page → video)

# 1. Extract page data into scene JSON
node scripts/url-to-scenes.js --url https://example.com/page --format reels --output scenes.json
# 2. Review/edit the generated scenes.json
# 3. Continue with voiceover + composition as above

See references/url-to-video.md for the full URL-to-video workflow.

Composition Template

import { AbsoluteFill, Audio, Series, staticFile } from "remotion";

// Import from your brand-config.md values
const COLORS = { primary: "#000", accent: "#888", dark: "#111", background: "#fff" };

export const AdTemplate: React.FC = () => {
  const { fps } = useVideoConfig();
  // Use actualDuration from info.json, not estimated
  const DURATIONS = { scene1: 3.42, scene2: 4.35, scene3: 4.12, scene4: 3.31 };
  const pad = 5;

  return (
    <AbsoluteFill>
      <Audio src={staticFile("audio/ad-example/ad-example-combined.mp3")} />
      <Series>
        <Series.Sequence durationInFrames={Math.round(DURATIONS.scene1 * fps) + pad}>

        {/* ... remaining scenes */}
      </Series>
    </AbsoluteFill>
