A framed copy of the empty stage appears beside you with a frame inside it, and the camera zooms through both back into your shot.
What you need
- Your clip. A vertical or landscape MP4 of you talking to camera, head and shoulders in shot. At least 2s long.
- No words. This effect shows none.
- The engine. Install
video-effectsbeside this skill and follow its setup once (ffmpeg, Node, Puppeteer, torch).
Run it
node ~/.claude/skills/video-effects/run.cjs infinite-zoom my-clip.mp4 infinite-zoom.mp4
It plays for 1.21s from --at (default 0.6s), then hands back to your shot. Change the length with --len. Add --check to test the fit and load without rendering.
What you get
infinite-zoom.mp4: 1080x1920, 30fps, H.264, your audio kept, the same length as your clip.
The effect itself is video-effects/fx/06-infinite-zoom.js. Edit that file to change it.
