Render Airdrop Carousel

Assemble a viral iOS "AirDrop" notification-carousel video ad (≈6–8s, 9:16) from a brand line plus 6–16 real product photos — a native AirDrop share-sheet card ("Brand would like to share a ___ · Decline / Accept") springs up and its preview window CYCLES through the products, landing on a range/lineup payoff with an Accept tap; a chime + soft per-swap ticks track the swaps. DETERMINISTIC assembly — an HTML card (real DOM text) rendered to PNG via headless Chrome, chroma-keyed, its magenta window refilled per-product in PIL, then animated + audio-synthed with FFmpeg. FREE (no paid model calls); the recipe supplies the brand line, product images, and payoff and gates the only optional paid step (a hero shot when the brand has NO usable photo → create-image-fal). Use for the airdrop-notification-carousel format.

About This Skill

render-airdrop-carousel

The free, deterministic renderer for the airdrop-notification-carousel video ad format — the viral iOS "AirDrop" trend where a native share-sheet card ("Brand would like to share a candle · Decline / Accept") springs up on the phone and its preview window flips through a carousel of real product photos, landing on a range/lineup payoff with an Accept tap.

This is a DETERMINISTIC composite — no generative video, no AI-rendered product. A real-DOM AirDrop card is rendered once to PNG (headless Chrome), chroma-keyed, and its preview window is refilled per-product in PIL, then animated + audio-synthed with FFmpeg. The whole point of the format is crisp system-UI text and real product photography, both of which a video model would smear. This capability makes no paid calls; the recipe gates the only optional paid step — generating a hero product shot when the brand has NO usable photo at all (→ create-image-fal).

Default output ≈ 6–8s, 1080×1920, h264 + aac. Duration is DERIVED, not trimmed — first_hold + (N-1)·per + final_hold. Add images or raise per to lengthen.

Scripts (free)

scripts/build_card.py — brand params → chrome.html + chrome-pressed.html: the AirDrop card on a green page (#00e000) with a magenta preview window (#ff00ff) and a solid brand band (wordmark SVG or text + tagline). Real DOM text — AirDrop, Decline, Accept, and the brand line are DOM/SVG, never AI-rendered.
scripts/one_shot.py — glue: build_card → headless-Chrome (Playwright) fullPage screenshot of both card states → compose_carousel. One --config, one MP4.
scripts/compose_carousel.py — the render engine: green-key the card → detect the magenta window → fill it per-product (cover-crop) → blurred per-product backdrop + push-in → card spring-up (iOS ease-out-back) + carousel + Accept tap → synth audio (whoosh on entry, chime on land, a tick per swap, a pop on the tap) → encode h264+aac.
scripts/config.example.json — the shape of the brand config the recipe binds (brand-neutral worked defaults; replace every /abs/path/... placeholder).

Chroma contract (load-bearing — build_card.py and compose_carousel.py MUST share it)

#00e000 green = page background, keyed to the card's alpha. #ff00ff magenta = preview window, replaced per product. Neither color may appear in the card art or any product photo — a product image containing near-pure green or magenta gets keyed/misread. Swap the image or tighten the window_mask thresholds if it bleeds.

Craft rules (faithful to the source molecule)

Real product photos only. The format's credibility is that these look like real AirDropped items — no AI-generated products in the carousel.
Never AI-render text — the card UI, wordmark, and band are DOM/SVG composited so they stay pixel-crisp. Cover-crop the window; white-bg PDP shots reading as "product in a white tile" is on-brand and fine.
6–16 images, ordered; end on the range — the payoff (final_image) should read as "the whole line" (lineup / family / all-shades).
Hard cuts on rhythm, a tick per swap — do NOT crossfade.
Never invent proof — a 1M+ sold tagline must be the brand's OWN stated figure, not filled from a brand-kit proof section.
Duration is derived, not trimmed — add images or raise per; never cut the audio.

Requires

Python 3 with numpy + Pillow, and ffmpeg/ffprobe on PATH.
Playwright chromium for the screenshot step (pip install playwright && playwright install chromium). If Playwright is unavailable, run build_card.py, screenshot chrome.html / chrome-pressed.html (fullPage) → chrome-green.png / chrome-green-pressed.png via the chrome-devtools MCP, then call compose_carousel.py directly.
watch (QC the final master). The recipe gates create-image-fal (optional hero shot when the brand has NO usable product photo) — the only paid, proxy-routed step.

Render Model Comparison Grid

Render a 'model comparison grid' video from a config — a fal-style "same prompt, N contenders" showcase — a dark real-DOM stage where per beat a monospace prompt fades in centered, docks to a small top strip, then a labeled 2-4 panel grid (static images OR muted video clips, mixable per cell) staggers in and holds for comparison, plus a minimal end card — frame-stepped via Playwright (video cells are frame-seeked deterministically) and encoded with FFmpeg. Deterministic assembly, FREE (cell media comes from create-image-fal / create-video-fal, music from create-music-elevenlabs), text stays pixel-crisp. Use for the model-comparison-grid format.

Render Offer Ad

Render a punchy ~12s vertical (9:16) music-only direct-response OFFER ad as a 4-beat kinetic-typography film — HEADLINE slam → real PRODUCT drop → CLAIM/proof → CTA pill — from one config of copy slots, a real product photo, a brand palette, fonts, bpm, and beat split. DETERMINISTIC + FREE (a bundled Remotion project; springs + interpolate, no AI-gen for visuals). Backgrounds are engine gradient divs off the palette, props are inline SVG, the ONLY composited bitmap is the REAL product photo (objectFit:contain, never stretched), and ALL headline/claim/CTA/URL/wordmark text is typeset in the engine — never AI-rendered (the format's credibility guard). A driver binds the config to Remotion input props, renders the 9:16 master, and derives a 1:1 center-crop with ffmpeg. Two gating checks run before render (claim verbs must match the product's physical format; the claim beat needs an edge-entry mechanism prop). Use for the motion-graphics-offer-ad format.

Render Myth Vs Fact

Assemble a myth-vs-fact kinetic-typography explainer video ad (≈29.5s, 9:16) from N myth/fact pairs + hook / turn / punch copy + palette + a brand end-card PNG + a VO track — a hook, 3 red-strike MYTH cards that flip to teal-check FACT cards (per-line strikethrough that crosses EVERY wrapped line), a "what actually works" turn, an optional proof reveal, a punch line, and a static end card. DETERMINISTIC assembly with ZERO AI-gen visuals — HTML hyperframes rendered frame-exact via Playwright (`window.renderAt(t)`, animation a pure function of beat-local time), Whisper beat-snap to VO word onsets, concat at a uniform fps, karaoke `.ass` captions burned last (suppressed on the proof + end-card beats), and a VO + optional music mix (music −20 dB, `amix normalize=0`, tail fade). FREE (Python + Playwright + ffmpeg); the recipe supplies the copy / palette / end-card / VO and gates the paid VO / music / Whisper calls to their own capabilities. Use for the myth-vs-fact format.
