What it does
Rebuilds the After Effects 3D-camera caption look as a deterministic per-frame painter for HyperFrames: caption groups sit at different depths so camera moves pull them apart, hero words hide behind the speaker through an alpha matte, and a ring of words turns in front. Prep scripts cut the take, build a reflect-padded plate and a local person matte with hyperframes remove-background, and measure font metrics; in-browser checks catch words leaving the frame or touching. It needs a locked-off talking-head shot and word timings from a transcriber you already run. A community-tier skill written by HeyGen's Jake Moran.
Use when
- 3D text or 3D camera captions on a talking-head video
- Words placed around or behind the speaker
- A camera move that flies through the captions
- Depth captions on an avatar video
Not for
- Plain subtitles (use HyperFrames)
- Moving or handheld shots, extreme close-ups, or subjects a matting model can't separate
