render-multiworld
Assemble a silent, music-led "multi-world product tour" ad (≈27s, 9:16) — a tour of three
distinct "third-place" worlds, one per product/scent, that lands on a Pinterest-style brand
end card. Each world is a two-shot pair: a ~4.5s WIDE kinetic-calm ARRIVAL (the
environment dominates, the bottle stays small) hard-cutting to a ~3.5s top-down MACRO
product MOMENT (the sealed bottle nested with its botanical companion). Scent identity is
carried by the world + botanical companion, not by bottle color. No VO, no captions in
the scenes — one music bed carries the whole thing.
This capability is the FREE, deterministic assembler. The paid steps — the six
per-world clips, the AI flat-lay end-card background, the ElevenLabs music bed — are
separate capabilities (see the gap below for the clips); the recipe orchestrates and gates
them.
Run
- Trim clips (FFmpeg, FREE) — trim each per-world clip to its
scene_grid[].duration_sec
(arrival 4.5 / macro 3.5), re-encode to the master spec (720×1280, 24fps, yuv420p,
scale+pad, audio stripped). Trimming the macro so the top-down portion dominates also
hides any label misrender at the clip's upright tilt extreme.
- End card (Playwright/HTML, FREE) — screenshot
end_card.html over the AI flat-lay
BACKGROUND, then FFmpeg-encode to a dwell_sec (3.0s) static clip. Headline
("FIND YOUR DAILY.", Inter 900), one handwritten Caveat scent label + hand-drawn SVG
arrow per bottle, Playfair wordmark + URL. End-card text is HTML, NEVER AI-rendered —
the AI step produces the background only.
- Hard-cut concat (FFmpeg, FREE) — concat the six trimmed clips in scene order
(S01 arrival → S02 macro → … → S06 macro) + the end-card clip. Hard cuts (no dissolves),
normalized to one fps/codec first so concat-copy is safe.
- Music mux + web encode (FFmpeg, FREE) — mux the single instrumental bed onto the
silent concat with
afade in/out + loudnorm I=-16:TP=-1.5:LRA=11, AAC 192k, clamped to
27.0s, explicit single-audio map so no silent scene-track leaks in → the H.264 (+ AAC)
720×1280 master.
Contract
- Deterministic + FREE (Playwright + PIL/HTML + FFmpeg); no paid calls, no AI-rendered
end-card text. Iterate the cut for free by re-running the assembly.
- Silent, music-led — no VO, no captions during the scenes; on-screen text appears
ONLY on the end card, HTML-composited.
- Per world = WIDE arrival (bottle small, environment dominant) → top-down macro (product +
botanical, no hands). Hard cuts between scenes; end card is a static hold with legible
HTML text; music starts at t=0 and fades the tail.
- Sealed-bottle rule is enforced at QC — trim/concat can't fix an open-cap or spraying
clip; that's a re-roll (paid), not an assembly fix. Identity via world + botanical, never
bottle color.
- The template recipe (DB) supplies the per-brand config (worlds, palettes, botanicals,
prompts, end-card copy, music mood); this capability is the generic assembler.
Gaps / routing notes
- The six per-world clips need a Higgsfield-proxy capability that does not exist. The
source molecule fires them through Higgsfield Marketing Studio
(
marketing_studio_video/product_showcase) grounded on imported product UUIDs, with the
sealed-bottle safety block front-loaded on every prompt. create-video-fal is a FAL i2v
proxy — a different provider and job shape — so it cannot serve this step. Wiring the clip
step to templates-as-data requires a create-video-higgsfield proxy (Marketing Studio
product_showcase, imported-product grounding, per-prompt safety block) that does not
exist yet. Until it lands, the clips are generated via the Higgsfield Marketing Studio
path directly (CLI/MCP) and that step is not a fetchable capability.
- The end-card background is an AI flat-lay render (text-free, all three sealed bottles +
botanicals) that in prod routes through create-image-fal (NB2); only the HTML text
overlay + encode run locally as FREE assembly.
- The music is a paid ElevenLabs call that in prod routes through
create-music-elevenlabs; only the loudnorm + fade + mux run locally as FREE assembly.
