A glass lens glides over your chest and magnifies what is under it, then opens out 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 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.
What you get
magnifying-lens.mp4: 1080x1920, 30fps, H.264, your audio kept, the same length as your clip.
The effect itself is video-effects/fx/03-magnifying-lens.js. Edit that file to change it.
