# YouTube Video Editing

## Inputs

Use voiceover files, image assets, animation plan, script scene table, captions, music/SFX preferences, and platform format.

## Process

1. Build the edit timeline from voiceover timing.
2. Place visuals and animations against narration.
3. Add captions or key on-screen text.
4. Add music and sound effects only where they improve clarity or energy.
5. Export in the correct YouTube format.
6. Watch or inspect the render for timing, audio, and visual issues.
