--- name: video-to-landing-page description: Turn any video into a cinematic scroll-driven landing page — Apple-style hero where scrolling progresses the visible frame through the video. Use when the user provides a video file and asks for "a landing page from this video", "scroll-frame website", "Apple-style scroll site", "hero that scrubs the video", "like the GitHub Copilot landing", or any equivalent. Extracts N evenly-spaced frames via ffmpeg, builds a self-contained HTML page with a sticky hero + JS scroll listener that swaps the visible frame as you scroll, plus headline, sections and CTA below. For YUV.AI projects, applies the yuv-design-system skill in Neon mode (pink/cyan/white, default for YUV.AI web) — Decks (purple/yellow) is reserved for slides only. For generic / non-YUV.AI projects, picks an appropriate palette per the source video. Output is one folder with `index.html` and a `frames/` directory — drop on any static host. --- # Video → Scroll-Driven Landing Page Build a cinematic landing page where the hero is a video playing **on scroll** instead of time — like Apple product pages or the GitHub Copilot landing. Frames are extracted from the source video and swapped as the user scrolls; below the sticky hero, normal-scroll sections carry copy and CTA. ## When to invoke - User drops a video and asks for a **landing page**, **scrolling site**, **scroll-frame hero**, or **website from a video** - Mentions of "Apple-style scroll", "GitHub Copilot landing", "scrub-on-scroll", "frame on scroll" - Hebrew equivalents: "דף נחיתה מסרטון", "אתר עם גלילה", "סרטון בגלילה" ## Save location **Default:** `~/Documents/yuv-projects/landings//` — always save landing pages here so you can find them again. Create the parent directory if missing. ```bash mkdir -p ~/Documents/yuv-projects/landings cd ~/Documents/yuv-projects/landings # Build / here. ``` Final path: `~/Documents/yuv-projects/landings//`. Tell the user where the landing lives at the end of every build. --- ## Workflow (8 steps) 1. **Probe the source** — `ffprobe` for duration, fps, dimensions, audio. 2. **Pick frame count** — default `80`. Floor `40` (choppy if lower), ceiling `160` (heavy page). Choose by duration: ≤10s → 50, 10–30s → 80, 30–60s → 120, >60s → 160. 3. **Decide output directory** — default `~/Documents/yuv-projects/landings//`. The `` is short, derived from the video name or the topic. Override only on explicit request. 4. **Extract frames** — run `references/extract-frames.py

[count]`. Outputs `output-dir/frames/f_0001.jpg`… with consistent JPG quality 82 and a max-width of 1920 (downscaled if source is larger). 5. **Copy and customise** `references/landing-template.html` into `output-dir/index.html`: - Replace the `__FRAMES__` placeholder with `` tags for each frame (the build script does this for you when you pass `--build-html`). - Fill in `__HEADLINE__`, `__TAGLINE__`, `__CTA_TEXT__`, `__CTA_HREF__`, sections. - For Hebrew content: set `` and swap fonts to Rubik/Assistant (see `references/design-notes.md`). 6. **Optimise frames** — the build script already scales to 1920px max-width. If the page total weight is > 12 MB, drop quality to 75 or reduce frame count. 7. **Preview** — `python -m http.server` inside the output directory and open `http://localhost:8000`. Scroll feels buttery on a decent machine. 8. **Deploy** — drop the folder on Vercel/Netlify/Cloudflare Pages. No build step needed. ## The scroll mechanic - Outer scroller `.scroll-stage` height set in viewport units (default `600vh` = scroll 5 screens to traverse all frames). - Sticky hero `position: sticky; top: 0; height: 100vh` containing all frames absolutely positioned and hidden except the active one. - Scroll listener computes `progress = scrolledIntoStage / scrollableHeight` clamped 0–1. - `idx = floor(progress * (N - 1))` — swap the `.active` class to that frame. - Wrap the listener in `requestAnimationFrame` to keep 60fps. ## Design rules - If the project is **YUV.AI-branded** (Yuval personally, his portfolio, his brand): call `yuv-design-system` and lock it to a mode by medium — - **Neon mode** (DEFAULT for YUV.AI web): hot pink (`#FF1464`) + neon cyan (`#00E5FF`) + white or rich black canvas. Anton + Inter (English) / Rubik + Assistant (Hebrew). 0px or 999px radii. - **Warm Editorial mode**: only for Hope, Marcus, bigcats.ai, practical.yuv.ai — pink + yellow + bone, off-white never pure `#fff`. - **Never use Decks mode (Fly High purple/yellow)** for a landing page — that palette is reserved for slide decks only. - If the project is **not YUV.AI-branded**: do not apply yuv-design-system. Pick a palette that fits the source video's mood. Anton + Inter remain reasonable defaults but aren't mandatory. - Hero overlays should be **subtle** — a vignette and a single big headline; don't drown the frame. - Below-hero sections: light canvas (white in Neon mode, off-white in Warm Editorial, bone if going generic-warm), large Anton heading, body copy in Inter at 18–22px, CTA as a sharp pill (`border-radius: 999px`) — pink fill in Neon mode, brand-appropriate color otherwise. - For Hebrew: respect RTL, use Rubik 900 for headlines, Assistant 400/500 for body. ## File references | File | Purpose | | --- | --- | | `references/extract-frames.py` | ffmpeg-based frame extractor; optionally builds the full HTML in one go | | `references/landing-template.html` | Self-contained landing-page skeleton with the scroll mechanic | | `references/design-notes.md` | Typography, palette, and motion defaults |
