Render 3d Product Showcase Agent Skill
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 (
afadein/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.

Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.
Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.
Improves the quality of images, especially screenshots, by enhancing resolution, sharpness, and clarity. Perfect for preparing images for presentations, documentation, or social media posts.
Downloads videos from YouTube and other platforms for offline viewing, editing, or archival. Handles various formats and quality options.
Lightweight WSI tile extraction and preprocessing. Use for basic slide processing tissue detection, tile extraction, stain normalization for H&E images. Best for simple pipelines, dataset preparation, quick tile-based analysis. For advanced spatial proteomics, multiplexed imaging, or deep learning pipelines use pathml.
