Assemble a cartoon music-video ad from a config: an animated / illustrated / hand-crafted story (stop-motion felt-and-foam, claymation, 2D toon, cut-out) where a sung song is the entire script and one recurring animated character carries every shot, cut to the bar with the climax line on the drop. This capability is the FREE, deterministic assembly — cut-to-bar, hard-concat, the logo bug + captions burn, and the solid-color end card.
scripts/config.example.json is the worked example (Coinbase "Bet on anything", ~55s 1080×1920
9:16, 16 body bars + a 3s end card — its felt look, character, story and song are that demo's
picks, never defaults); scripts/PIPELINE.md maps every config block to its source
step and scripts/README.md documents the free assembly.
The creative calls are the caller's (the video-format recipe asks the user); this assembly never picks them. The demo's value is an example only:
This is the FREE, deterministic assembly stage — it spends nothing. The paid inputs are
separate capabilities: the sung song (create-music-elevenlabs, or a user-supplied mp3 + Whisper
word timings) beat-tracked with librosa so the BAR GRID sets the timeline; one locked recurring
character + one keyframe per bar in one look pack (create-image-fal, Nano Banana); and one
Seedance i2v clip per bar (create-video-fal). Given the song + word-timestamps.json +
bars.json + one clip per bar + the brand wordmark SVG, render-cartoon-music-video cuts each
clip to its bar window, hard-concats on the bar, burns the logo bug + captions, appends the
solid-color end card, and muxes the song under it → the master. Re-cuts reuse the existing song /
keyframes / clips and cost $0.
