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.

Required Tools

command -v magick
command -v ffmpeg
command -v ffprobe
python3 --version

Generate Buddy Visemes

python3 scripts/generate_buddy_v12_visemes.py \
  ~/.hermes/assets/prismtek-youtube/avatar/buddy-host-main-clean.png \
  --out-dir ~/.hermes/assets/prismtek-youtube/avatar

Render a Proof Clip

python3 scripts/prismtek_youtube_avatar_lipsync.py \
  /path/to/base-video.mp4 \
  --closed ~/.hermes/assets/prismtek-youtube/avatar/buddy-host-main-v12-mouth-closed.png \
  --open ~/.hermes/assets/prismtek-youtube/avatar/buddy-host-main-v12-mouth-small-open.png \
  --output /tmp/buddy-lipsync-proof.mp4 \
  --limit-seconds 20

For full render, omit --limit-seconds.

Operator Notes

This skill renders local media only. Keep source media, generated avatars, rendered MP4s, and receipts out of public git history.
