Workflow for Adding Audio to Remotion Videos

1. Write voiceover script - Break into segments matching scene timing
2. Generate voiceover - Use Eleven Labs via WaveSpeed for each segment
3. Generate SFX - Use MMAudio V2 for transitions, notifications, success sounds
4. Download audio files - Save to public/audio/ in Remotion project
5. Add Audio component - Use Remotion's <Audio> component with proper timing

Remotion Audio Component Example

import { Audio, Sequence, staticFile } from "remotion";

// In your composition:
<Sequence from={0} durationInFrames={100}>
  <Audio src={staticFile("audio/voiceover-scene1.mp3")} />
</Sequence>

Environment Variables

Store in ~/.claude/.env:

• WAVESPEED_API_KEY - WaveSpeed AI access (includes Eleven Labs, Flux, MMAudio)
• KIE_AI_API_KEY - Kie AI access (for Suno music)
