- description: Assemble a premium 3D product-showcase ad from a config — four beat clips (a 360 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/PIL brand end card, and mixed under one instrumental bed at loudnorm I=-16 (music-only, no VO). This is the FREE deterministic assembly stage (last-frame extract, end-card hyperframe, normalize, concat, music mix); the rotation/macro clips come from Marketing Studio, the reveal from Veo3 i2v, and the bed from create-music-elevenlabs. Use for the 3d-product-showcase format.

# render-3d-product-showcase

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 — a 360 hero

+ 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", ~14s

- 720×1280 9:16); `scripts/PIPELINE.md` maps every config block to its source step and

- `scripts/README.md` documents the free 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) come from Higgsfield

- Marketing Studio `product_showcase` Hyper Motion off the imported PDP product (real label,

- never AI-invented) via `create-video-fal`; Beat 3 (the physics reveal) is a Veo3

- image-to-video seeded on Beat 1's last frame (`create-video-fal`); the one instrumental bed

- is `create-music-elevenlabs` (`force_instrumental` true). Given those beats + the brand

- wordmark, `render-3d-product-showcase` extracts Beat 1's last frame, builds the Playwright

- end-card hyperframe, normalizes each beat to the brand canvas, hard-concats, mixes the bed,

- and muxes → the master. Re-cuts reuse the existing beats and cost **$0**.

+ 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:

+ 1. `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).

+ 2. `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 label is never AI-invented.

- - **End card via Playwright/PIL from the real wordmark — never AI-render brand text.** The

- brand close is a deterministic hyperframe (Beat 1 last frame + scrim + Playfair headline

- spring-rise + the real wordmark fade-in); a diffusion model garbles a wordmark. Render at

- 1080×1920 then ffmpeg-scale to 720×1280 (matching the viewport to the output clips the edge).

- - **Normalize each beat to the brand canvas, hard-concat.** Per beat: strip the MS auto-audio

- (`-an`), scale + pad to 720×1280 with the brand `bg` pad color, 24fps, yuv420p, crf 18 →

- concat demuxer. No dissolves.

+ 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
