render-stopmotion-hand-swatch-cycle

Assemble a stop-motion hand-swatch-cycle ad from a config: a fast, tactile product demo where a single hand swipes ONE cosmetic barrel across a cream "skin-patch" test surface, and the shade of the barrel AND the painted swatch stripe changes on every frame while the hand, background, crop, and lighting hold still — cycling the variant family so the viewer self-identifies their match, then a hero-pick payoff and a branded end card. This capability is the FREE, deterministic assembly — the per-plate PNG→mp4 loop encode, the concat-demux, the end-card render, and the music mux.

scripts/config.example.json is the worked example (DIBS Beauty "Pick Your Match", ~16.6s 1080×1920 9:16, ~24 cycle plates + finale beats + a 3s end card); scripts/PIPELINE.md maps every config block to its source step and scripts/README.md documents the free assembly.
