Video To Superprompt

Video To Superprompt

Goal

Convert any usable reference video into a builder-ready prompt that captures what the video shows, how it moves, how it should be rebuilt, and what assets or generated media are needed. The default output is one paste-ready prompt unless the user asks for an article, asset pack, or implementation.

Workflow

1. Locate the source video.

   • Accept local paths, uploaded files, URLs, browser-visible videos, article assets, or repo media.
   • If the video is referenced but inaccessible, ask for the exact file or URL before inventing details.
   • If the user wants exact recreation, inspect any source HTML/CSS/JS or local page connected to the video before writing the prompt.

2. Inspect the video technically.

   • For local files, run ffprobe for duration, dimensions, frame rate, codec, and size.
   • Extract representative frames with ffmpeg, favoring timeline beats over uniform thumbnails.
   • Suggested quick pass:

     ffprobe -v error -show_entries format=duration,size:stream=width,height,r_frame_rate -of json "$VIDEO"
     mkdir -p /tmp/video-frames
     ffmpeg -y -i "$VIDEO" -vf fps=1 /tmp/video-frames/frame-%03d.jpg
     

   • For long or scroll-heavy videos, also extract start/middle/end and visible transition moments.

3. Analyze in layers.

   • Story: page/app purpose, emotional arc, section order, transition between beats.
   • Screen/layout: viewport framing, grids, sticky zones, cards, media, overlays, margins, navigation, footer.
   • Motion: reveal timing, easing, parallax, masks, pinned sections, scroll scrubbing, hover/tap states, looped ambient motion, camera moves.
   • Visual design: typography, color palette, surfaces, borders, shadows, texture, iconography, image/video treatment.
   • Technical rebuild: CSS/native APIs, IntersectionObserver, Web Animations API, GSAP ScrollTrigger, Lenis, Framer Motion/Motion One, Three.js/WebGL, canvas, video currentTime scrubbing, carousels, or other domain libraries.
   • Accessibility/performance: reduced motion, mobile behavior, touch/keyboard states, lazy loading, video preload, pixel-ratio caps, static fallbacks.

4. Plan assets.

   • Produce an asset map. Include exact URLs when supplied, local filenames when used, or placeholder names when assets still need generation.
   • If AI assets are needed, create separate prompts for image plates, video clips, WebGL/canvas elements, posters, sprites, masks, and texture overlays.
   • If user names specific models or APIs, preserve them exactly in the prompt and separate image prompts from video prompts.

5. Write the superprompt.

   • Use a single fenced text block for the paste-ready prompt unless the user asks for another format.
   • Start with the final thing to build and the reference boundary: exact recreation vs inspired adaptation.
   • Include: asset map, brand/content, global design language, layout rules, section-by-section anatomy, motion system, scroll system, video behavior, WebGL/Three.js behavior, responsive requirements, accessibility/performance, and anti-patterns.
   • For every major section, specify purpose, layout, visual details, animation, interactions, scroll behavior, library/API choice, and reduced-motion fallback.
   • Avoid vague phrases like “make it beautiful,” “similar animation,” or “nice transitions.” Convert taste into concrete build instructions.

6. Verify before finalizing.

   • Check that all asset paths/URLs in the prompt exist or are clearly marked as placeholders.
   • If screenshots/frames were created, confirm files are non-empty and representative.
   • If writing an article or repo artifact, obey local workspace instructions, keep dirty-worktree staging narrow, and commit when required.

Output Modes

• Prompt only: Give the paste-ready prompt and, when helpful, a short asset map above it.
• Article: Create content.md plus local frame/video evidence, manifest, and prompts. Follow the current repo article conventions.
• Implementation brief: Add a build plan and QA checklist after the prompt.
• Asset-generation pack: Split prompts into background images, video clips, sprites/WebGL, posters, and final page prompt.

Quality Bar

• The prompt should be long enough to rebuild the interaction without seeing the original video.
• It should preserve the video’s sequence, pacing, and notable quirks.
• It should name exact motion mechanisms: pinned section, scrubbed timeline, video.currentTime, parallax layer, opacity reveal, transform, mask, shader, particle field, hover state, or carousel physics.
• It should include mobile behavior and reduced-motion behavior every time.
• It should call out what to avoid, especially generic landing-page sections, decorative blobs, mismatched stock media, autoplay-only video when scroll-scrubbing is required, and text overlap.
