A ring of blue light opens below your chin, filled with a turning swirl, and the camera flies through it 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 portal my-clip.mp4 portal.mp4
It plays for 1.02s 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
portal.mp4: 1080x1920, 30fps, H.264, your audio kept, the same length as your clip.
The effect itself is video-effects/fx/04-portal.js. Edit that file to change it.
