Compose Creator Layer

An ffmpeg-based skill that composites a generated creator track over a product footage layer beat by beat, with a voice-led audio mix normalised to -14 LUFS.

What it does

  • Runs compose.py to composite a creator video over a rendered product layer per beat.
  • Placement follows beat type: inside the creator's zone on split beats, full frame on creator beats, hidden on product beats.
  • Three audio modes: creator voice (with sidechain-ducked music bed), music-only for voiceless paid ads, or a silent master for organic posts where the track is added in-platform.
  • Normalises the mix to -14 LUFS and uses --head to control vertical crop so the subject's head stays in the upper third.
  • Deliberately applies no colour grade; caption burn-in is handled later by caption-burn.

Who it's for

  • Performance marketers and editors shipping short-form UGC ad reels at volume.
  • Teams already using the repo's footage-cutlist and create-creator-takes-h3 pipeline.
  • Anyone who must ship paid and organic cuts separately for music licensing reasons.

Example uses

  • "Composite creator.mp4 over layer.mp4 using cutlist.aligned.json and write reel.mp4" → default run.
  • "Add bed.mp3 at -20 dB, ducked under the voice" → --music bed.mp3 --music-db -20.
  • "Give me a silent master for the organic Instagram post" → --audio none.
