Prismtek YouTube Buddy Lip-Sync
Use this skill to turn a clean Buddy host PNG into a lightweight audio-reactive talking-host overlay for Prismtek/Buddy videos.
The workflow is intentionally simple and robust:
- no ML lip-sync dependency;
- no face-swap, cloning, impersonation, or deepfake pipeline;
- no private media assets committed;
- ImageMagick for deterministic pixel-art mouth/viseme generation;
- FFmpeg/ffprobe for audio RMS analysis and video compositing;
- JSON receipts for repeatable render review.
