Summary

Assemble a stop-motion hand-swatch-cycle product-demo ad from a config — a sequence of still PLATES (one hand swiping a single-barrel cosmetic across a cream skin-patch, the barrel + swatch changing per plate while the hand, background, crop, and lighting stay locked) is PNG→mp4

2
3	Assemble a stop-motion hand-swatch-cycle ad from a config: a fast, tactile product demo where a
4	single hand swipes ONE cosmetic barrel across a cream "skin-patch" test surface, and the shade of
5	the barrel AND the painted swatch stripe changes on every frame while the hand, background, crop,
6	and lighting hold still — cycling the variant family so the viewer self-identifies their match, then
7	a hero-pick payoff and a branded end card. This capability is the FREE, deterministic assembly —
8	the per-plate PNG→mp4 loop encode, the concat-demux, the end-card render, and the music mux.
9
10	`scripts/config.example.json` is the worked example (DIBS Beauty "Pick Your Match", ~16.6s 1080×1920
11	9:16, ~24 cycle plates + finale beats + a 3s end card); `scripts/PIPELINE.md` maps every config
12	block to its source step and `scripts/README.md` documents the free assembly.
13
14	## Run
15
16	This is the FREE, deterministic assembly stage — it spends nothing. The paid inputs are separate
17	capabilities — the master-anchor plate + the per-shade / motion / finale plates + the end-card hero
18	BG (`create-image-gpt-image-fal`, gpt-image-2 EDIT mode, each plate anchored to the SAME
19	master-anchor — never chained), and the music track (`create-music-elevenlabs`, or a brand-supplied
20	mp3). Given the ordered plate PNGs + per-plate holds + the end-card hero BG + the brand logo SVG +
21	the music track, `render-stopmotion-hand-swatch-cycle` loop-encodes each plate at its hold,
22	concat-demuxes with hard cuts into a silent master, appends the HTML-rendered end card, and muxes the
23	music under it → the master. Re-cuts (re-timed holds, a re-ordered cycle, a swapped end card) reuse
24	the existing plates / track and cost $0.
25
26	## Contract (the free assembly)
27
28	- Still plates, not i2v — held for tuned durations. Each plate is a static PNG loop-encoded
29	(`ffmpeg -loop 1 -t <pose_hold_ms>`) to 1080×1920 @ 30fps crf18. This is stop-motion — discrete
30	held frames, no camera moves, no character animation. Do not animate the plates.
31	- Fast stop-motion cadence, HARD cuts. Motion / half-painted plates hold 150–250ms, per-shade
32	plates ~380ms (or ~1000ms for a slower cycle), hero / bookend beats 1100–1800ms; average ~380ms.
33	Concat-demux the plate mp4s in order with hard cuts (`ffmpeg -f concat`) — NO dissolves. The
34	frame-swap tactility is the whole point; a crossfade erases it.
35	- Concat-demux, not filter_complex. The plates are silent stills, so the `concat` demuxer over
36	the ordered plate list is correct and cheapest. (`filter_complex` is only needed when clips carry
37	mismatched audio — these don't.)
38	- The music carries it — no VO. A pre-sourced brand instrumental (128–130 BPM works well),
39	volume ≈0.4, fade in/out. Do not add a spoken voiceover or a second bed.
40	- End card via Playwright HTML from the real logo SVG — never AI-render brand text. A serif
41	tagline + sans subtitle + the real logo SVG composited over a hero product/swatch BG by an HTML
42	template (Chromium headless), rendered to a silent ~3s clip. A diffusion model garbles a wordmark.
43	- Music plays UNDER the end card with a fade tail — no silent tail. Mux the track over the whole
44	video including the end card, fade over the last ~0.5s so the video ends WITH the music.
45	- FFmpeg composite, deterministic, FREE. Loop-encode each plate, concat-demux on hard cuts,
46	append the end card, mux the music with a fade tail → a 1080×1920 h264+aac master (~16.6s). No paid
47	calls, no keys (beyond the Playwright/Chromium the end-card render needs).
