render-brand-identity-reveal

Render the 'brand identity reveal' format from a config. The signature is a single fixed poster frame in a REAL, softly-lit space (the illuminated poster-frame look of a shop, café, cinema or metro — the setting and wall are chosen per video): a real wall, a real soft-focus plant in the lower-left corner, dappled leaf shadow. The artwork INSIDE the frame HARD-CUTS (no crossfade) through 11 beats — 10 on-brand poster mockups + a brand END CARD held ~3s. Music bed only, NO voiceover; copy is baked into each mockup, never overlaid as captions.

This capability is the FREE assembly only. The paid parts are separate generic capabilities the recipe names — create-image-fal (the one-shot environment plate) and create-music-elevenlabs (the bed). Never re-implement them here.

Choices

The calling recipe asks the user these before any paid step; this capability only reads them from config. The worked example (Palmglow) values are examples, never defaults.

• setting — where the frame hangs → config.plate.setting (demo: premium boutique interior).
• wall_style — the wall it is mounted on → config.plate.wall_style (demo: sage subway tile).
• music — the bed's genre/mood → config.music.direction (demo: upbeat playful pop).

Three layers

1. Environment plate (PAID, create-image-fal, flux-pro ultra, 9:16) — an empty lit poster frame in a real space, high-res so the camera can be pushed closer by cropping. Pick a wall color that makes the brand's poster colors POP (complement of the dominant hue).
2. Mockups (FREE) — real-DOM HTML/CSS (scene.html), one poster per beat, built from the brand's real assets + approved copy, frame-stepped via Playwright (render_art.py, bare mode, device_scale_factor 2).
3. Composite (FREE) — measure_frame.py detects the blank poster interior quad; composite.py perspective-warps each poster into it AND multiplies the plate's real leaf-shadow/light back onto the poster (so it reads as behind glass) + a glass sheen; build_video.sh sequences the frames with the music bed.

Inputs

• config.json — copy scripts/config.example.json (the Palmglow worked example) and edit (canvas, plate prompt + setting + wall_style from the user's choices, camera crop, per-beat durations, end-card copy). Schema + per-file working-dir layout are documented in scripts/PIPELINE.md.
• The brand's REAL product/packaging/lifestyle stills, wordmark, and icon (recreate the icon as an SVG <mask> if the only source has an occluding element). Approved copy only.

Workflow (free assembly)

CAP=skills/video/render-brand-identity-reveal
RUN=<project>/working    # holds scene.html + assets/ + the create-image-fal plate in bg/

python3 $CAP/scripts/recrop.py 0.72 0.13      # camera distance (bigger frac = bigger frame); src = first bg/plate_*.png
python3 $CAP/scripts/measure_frame.py         # detect the blank poster interior quad
python3 $CAP/scripts/render_art.py            # render each poster standalone (Playwright, dsf 2)
python3 $CAP/scripts/composite.py             # warp into frame + shadow multiply + sheen
bash    $CAP/scripts/build_video.sh $RUN/concat.txt $RUN/music.mp3 out.mp4 13.05 1.0

Then watch the master (music-only, every poster legible, shadow falls across the art, end card holds). See scripts/PIPELINE.md for adapting scene.html per brand.

Rules

• Approved brand copy ONLY — never invent claims, customers, results, or testimonials.
• Toggle beats with OPACITY, not display (a per-state display:flex silently overrides a display:none toggle and paints one state over all others).
• Camera distance = re-crop the high-res plate (recrop.py), don't regenerate.
• The realism trick = MULTIPLY the plate's real shadow/light back onto each composited poster.
• Music bed only, no VO. Close on the brand end card.

Failure Modes

• Every rendered frame identical → a per-beat display: rule beat the visibility toggle; use opacity.
• Playwright evaluate(fn, arg) didn't switch state in a loop → bake the beat index into the JS string and return the applied state to assert it.
• Composited poster looks pasted-on → you skipped the shadow multiply (shadow_strength ~0.85).
• Studio product won't cut out (white cap == seamless bg) → present as a photo-tile, don't corner-flood-fill.
• Playwright missing under node → use the python playwright + cached chromium.
