description	Assemble a premium 3D product-showcase ad from a config — four beat clips (an orbiting hero rotation, a macro push-in, a physics reveal, a typographic close) normalized to the brand-color canvas, hard-concatenated in order, closed on a deterministic Playwright brand end card, and mixed under one instrumental bed at loudnorm I=-16 (music-only, no VO). Ships the runnable build_endcard.py + build_masters.py; the rotation/macro clips are create-video-fal i2v seeded on a create-image-fal styled hero, the reveal is Veo3 i2v, and the bed is create-music-elevenlabs. Use for the 3d-product-showcase format.

Assemble a premium 3D product-showcase ad from a config: one real product floats centered on a clean seamless brand-color backdrop and sells itself across four beats — an orbiting hero rotation, a macro push-in on the surface detail, a physics reveal (exploded_view / particle_disintegration / liquid_splash, or rotation_only), then a typographic brand close. This capability is the FREE, deterministic assembly that stitches the delivered beats into the master; it spends nothing.

scripts/config.example.json is the worked example (DIBS Beauty "Desert Island Duo", ~15s 720×1280 9:16); scripts/build_endcard.py + scripts/build_masters.py are the runnable free assembly; scripts/PIPELINE.md maps every config block to its source step; scripts/README.md documents the assembly.

Run

This is the FREE, deterministic assembly stage — it spends nothing. The paid inputs are separate capabilities: Beats 1 & 2 (hero rotation + macro push-in) are create-video-fal image-to-video seeded on a create-image-fal styled hero — a nano-banana restyle of the brand's REAL product photo onto the seamless studio set, so the product geometry is real and never AI-invented; Beat 3 (the physics reveal) is a Veo3 image-to-video seeded on Beat 1's last frame (also create-video-fal); the one instrumental bed is create-music-elevenlabs. There is no Higgsfield / Marketing Studio in this format — everything paid runs through the fal-proxy / elevenlabs-proxy so it bills the Ads agent.

Given those beats + the brand wordmark, this capability:

build_endcard.py --bg beat1_last_frame.png --headline "…" --wordmark <wordmark> --out endcard.png — the deterministic Beat-4 hyperframe (Playwright 1080×1920 → ffmpeg-scale to 720×1280).
build_masters.py --config config.json --clips working/clips --endcard endcard.png --music music.mp3 --out master.mp4 — trims each beat to its window, normalizes to the brand canvas, hard-concats, mixes the bed.

Re-cuts reuse the existing beats and cost $0.

Contract (the free assembly)

Music-only, no VO. One ElevenLabs instrumental bed carries the film; nobody speaks. Do not add a spoken voiceover or a second bed.
Beat 1's last frame is the shared anchor. Extract it (ffmpeg -sseof -0.1 … -frames:v 1) once — it seeds the Veo3 Beat 3 AND backs the Beat 4 end-card hyperframe, so the product + lighting carry across all four beats and the geometry never AI-drifts.
End card via Playwright from the real wordmark — never AI-render brand text. The brand close is a deterministic hyperframe (Beat 1 last frame + scrim + Playfair headline + the real wordmark, recolored for contrast). build_endcard.py auto-picks a legible headline color from the bg luminance and renders 1080×1920 then scales to 720×1280. Playfair is loaded from Google Fonts; bundle the .ttf if determinism offline matters. If the resolvable Playwright wants an uninstalled browser build, export PW_CHROME=<installed Chromium binary> (shoot.js honours it).
Normalize each beat to the brand canvas, hard-concat. Per beat: trim to the window, strip the i2v model's auto-audio (-an), scale + pad to 720×1280 with the brand bg pad color, 24fps, yuv420p, crf 18 → concat demuxer. No dissolves.
FFmpeg mix, deterministic, FREE. Mix one instrumental bed (afade in/out + loudnorm I=-16 TP=-1.5 LRA=11, apad + atrimmed to master duration) over the concatenated beats → a 720×1280 h264+aac master. No paid calls, no keys.
