magnifying-lens

A glass lens glides over your chest and magnifies what is under it, then opens out back into your shot.

What you need

1. Your clip. A vertical or landscape MP4 of you talking to camera, head and shoulders in shot. At least 2s long.
2. No words. This effect shows none.
3. The engine. Install video-effects beside this skill and follow its setup once (ffmpeg, Node, Puppeteer, torch).

Run it

node ~/.claude/skills/video-effects/run.cjs magnifying-lens my-clip.mp4 magnifying-lens.mp4

It plays for 1.49s 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.
