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 chosen backdrop colour, 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 backdrop (colour and lighting chosen per brand) 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 (Quillmere Pen Co. "Meridian 14", ~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.

Choices

The recipe asks these before any paid step; this capability only assembles their result. The demo's value is an example, never a default:

• **`backdrop`** → `studio_look.bg` (the pad colour `build_masters.py` uses) + the beat prompts.

Demo: deep teal `#1F4E5A`.

• **`lighting_mood`** → `studio_look.lighting_preset` / `rim_light` + the beat prompts. Demo:

`luxe_botanical_warm` (warm rim light upper-right, warm bokeh).

• **`reveal`** → `reveal_variant` + `beats[2]`. Demo: `exploded_view`.
• **`music`** → `music.prompt` (the bed passed to `build_masters.py --music`). Demo: minimal

ambient-electronic, drop at 7s, 100 BPM.

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 the call is charged to your GooseWorks credits.

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 spend nothing.

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 + serif headline — `--headline-font`, Playfair Display by default — + 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. The headline font 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.
