Assemble a narrated-UGC "stitch reply" ad from a config — a single spoken VO carries a verbatim testimonial while ~30 per-cut i2v clips (one creator across ~5 wardrobes in ~3 worlds, plus product B-roll) are each trimmed to their EDL window built from the VO's Whisper word boundaries and hard-concatenated via filter_complex concat (never the demuxer, which drops audio on a duration mismatch), the VO mixed over an optional sidechain-ducked instrumental bed (−20dB, 20 to 1) so the VO stays on top,

Assemble a narrated-UGC "stitch reply" ad from a config: a fast-cut vertical testimonial where a single spoken VO carries a verbatim ~13-sentence testimonial over ONE creator across ~5 wardrobe changes in ~3 micro-worlds, interspersed with product B-roll (e.g. product macro, unboxing, a landing-page scroll), ~30 hard cuts on the VO cadence, closing on a brand end card. This capability is the FREE, deterministic assembly — trim-to-EDL, hard-concat, the VO+music mix, the karaoke-pop caption burn, the landing-page zoompan, and the end-card append.
scripts/config.example.json is one worked example (Bioma "Do NOT buy Bioma Probiotics", ~37s
1080×1920 9:16, ~30 body cuts + a ~2s end card) — its creator, voice, hook, worlds and music are
that demo's answers, not defaults; scripts/PIPELINE.md maps every config block to
its source step and scripts/README.md documents the free assembly.
The creative calls are made upstream by the user (the recipe's choices) and arrive in the config;
this assembly never picks them.
character.descriptor / character.name. The demo used a
28-year-old blonde woman.vo.voice_id / vo.settings. The demo used an excited voice
matched to its creator.vo.hook_line / vo.script_md / vo.payoff_line. The
demo used a "Do not buy " reversal.worlds.briefs. The demo used bedroom / kitchen / bathroom.audio_mix.music_brief. With "no music", skip the bed
and mix the VO alone.This is the FREE, deterministic assembly stage — it spends nothing. The paid inputs are
separate capabilities — the spoken VO (create-vo-elevenlabs) Whisper-aligned so the WORD
BOUNDARIES set the cut grid; one locked creator (create-image-gpt-image-fal anchor + ~5 wardrobe
edits chained off the anchor) + 3 world wides + per-cut start-frames (create-image-fal product
composites); and one Veo/Seedance i2v clip per cut (create-video-fal). Given the VO +
vo-final.words.json + edl.json + one clip per cut + a Playwright landing-page PNG + the brand
end-card PNG, render-narrated-ugc-wardrobe-stitch trims each clip to its EDL window, hard-concats
on the VO cadence, mixes the VO over the ducked bed, burns the karaoke-pop captions, appends the
end card → the master. Re-cuts reuse the existing VO / start-frames / clips and cost $0.
