HyperFrames Creative

Brand, pacing, style, narration, and composition direction. Use after the technical contract from hyperframes-core is in place.

For motion patterns, scene blueprints, transitions, and CSS marker effects, use hyperframes-animation — this skill is intentionally non-animation.

Read these two FIRST for any non-trivial composition — they override web instincts:

  • references/house-style.md — "interpret the prompt, generate real content," the lazy-default list, and the background/foreground layer recipe. This is what turns a literal restyle into a concept.
  • references/video-composition.md — video-medium density, scale, foreground metadata (the "produced, not generated" detailing: data bars, registration marks, monospace readouts, 8-10 elements/scene).

Skipping these is the single biggest cause of generic, web-page-looking output. They are not optional rows in the routing table below — for anything beyond a one-line edit, open both before you choose colors or write HTML.

Workflow

  1. If a project has a design spec, read it first and treat its frontmatter tokens as brand truth (colors, fonts, spacing, tone, constraints). Which file to read (precedence frame.md → design.md → DESIGN.md) and how to parse it (frontmatter = normative, prose = context) are defined once in references/design-spec.md — resolve and load per that doc.
  2. If no design spec exists and the user asks for visual direction, choose a route:
    • Ready-made frame-preset (optional) → frame-presets/ (adopt a FRAME.md as frame.md; see references/design-spec.md)
    • Named style or mood → references/visual-styles.md
    • Fast defaults → references/house-style.md
    • Interactive selection → references/design-picker.md
  3. For multi-scene work, plan beats and rhythm before writing HTML → references/beat-direction.md. For scene transitions, jump to hyperframes-animation/transitions/.
  4. For motion-heavy work, read references/motion-principles.md (high-level guardrails), then go to hyperframes-animation for atomic rules.

Scripts

  • scripts/contrast-report.mjs — inspect contrast warnings from rendered frames.
  • scripts/extract-audio-data.py — pre-extract audio bands for audio-reactive compositions.
  • scripts/package-loader.mjs — support script for bundled creative tooling.

Run from the repo root with explicit paths, for example:

python skills/hyperframes-creative/scripts/extract-audio-data.py <audio-file>

Animation analysis (animation-map.mjs) lives in hyperframes-animation/scripts/.

Boundaries

  • Do not override hyperframes-core technical rules.
  • Do not require a design system for a minimal technical composition.
  • Do not add extra scenes, narration, music, captions, or transitions unless the request calls for them or you first propose the expansion.
  • Keep recipe references task-specific; do not read every reference for simple edits.

Video and audio processing with FFmpeg. Use for format conversion, resizing, compression, audio extraction, and preparing assets for Remotion. Triggers include converting GIF to MP4, resizing video, extracting audio, compressing files, or any media transformation task.

9018/mychat

Use when implementing Disney's 12 animation principles with Framer Motion in React applications

9018/mychat

All animation knowledge for HyperFrames — atomic motion rules, multi-phase scene blueprints, scene transitions, broader motion-design techniques, AND the seven runtime adapters (GSAP default, plus Lottie, Three.js, Anime.js, CSS keyframes, Web Animations API, TypeGPU). Use for any motion or animation task: pick 2-4 rules and compose, or load a blueprint, or look up runtime-specific API (e.g. GSAP eases / Lottie player / Three.js mixer). HyperFrames-native: single paused timeline, seek-safe, deterministic.

9018/mychat

HyperFrames CLI dev loop. Use when running npx hyperframes init, add, catalog, capture, lint, validate, inspect, layout, snapshot, preview, play, render, publish, lambda, doctor, browser, info, upgrade, skills, compositions, docs, benchmark, telemetry, transcribe, tts, or remove-background, or when troubleshooting the HyperFrames build/render environment. Entry point for AWS Lambda cloud rendering (`hyperframes lambda deploy / render / progress / destroy / policies`).

9018/mychat

The HyperFrames composition contract — build one renderable project. Use for composition structure, the `data-*` timing attributes, `class="clip"`, tracks, sub-compositions, variables, framework-owned media playback, deterministic-render rules, and validation. Read before writing composition HTML.

9018/mychat

Audio and media assets for HyperFrames compositions, produced by one shared audio engine (`scripts/audio.mjs`) — multi-provider TTS (HeyGen / ElevenLabs / Kokoro local), background music + sound effects (HeyGen audio-library retrieval by default, with local Lyria / MusicGen BGM generation and a bundled SFX library as the no-credential fallback), Whisper transcription, background removal, and caption authoring. Use for voiceover / TTS, BGM, SFX / sound effects, transcription, captions / subtitles / lyrics / karaoke / per-word styling, voice + provider selection, and music-mood prompting.

9018/mychat

Install and wire registry blocks and components into HyperFrames compositions. Use when running hyperframes add, installing a block or component, wiring an installed item into index.html, or working with hyperframes.json. Covers the add command, install locations, block sub-composition wiring, component snippet merging, registry discovery, and authoring a new block or component to contribute upstream (idea → scaffold → validate → PR).

9018/mychat

Use when the user wants a short, design-led motion graphic where motion is the message: kinetic typography, stat or number count-up, chart/data-viz hit, logo sting, brand lockup, lower-third, callout, social overlay, animated headline/tweet/news item, motion poster, or quick captured-page highlight. Usually under 10s and up to ~30s, with no narration arc, voice-over, or live-action subject. Can render to MP4 or transparent overlay. Not for longer, multi-scene, narrated, or brand-reel pieces (use general-video), narrated website videos (website-to-video), topic explainers (faceless-explainer), product promos (product-launch-video), PR videos (pr-to-video), or captions on existing footage (embedded-captions). When unsure whether it's a quick motion-first piece or a longer / narrated treatment, see /hyperframes.

9018/mychat

Use when the user has a music track (an audio file, or a video to pull audio from) and wants a beat-synced HyperFrames video, calm to hard-hitting. The music drives everything: one analyzer reads it once, the orchestrator lays out the frames and fills a per-frame plan, and one sub-agent builds each frame. Typography and templates are the floor — a complete video needs zero assets — but any images or videos the user supplies are cut into the frames on the same beat grid (beat-cut / ken-burns). The genre (lyric video, slideshow, kinetic promo) falls out of the per-frame choices; the pipeline never branches on it.

9018/mychat

Toolkit-specific Remotion patterns — custom transitions, shared components, and project conventions. For core Remotion framework knowledge (hooks, animations, rendering, etc.), see the `remotion-official` skill.

9018/mychat

Port an existing Remotion (React) composition to HyperFrames HTML. Use ONLY when the user explicitly asks to port/convert/migrate/translate a Remotion source. Do NOT use: (a) authoring a new HyperFrames composition; (b) Remotion mentioned in passing; (c) Remotion code shared as reference only; (d) "same video as my Remotion one" without explicit migrate request — treat as fresh build. Doubt → `/general-video`. One-way, Remotion-only: no reverse export (HyperFrames→Remotion or any framework), no non-Remotion source (After Effects, Framer Motion, plain React/CSS) → out of scope, re-create via `/general-video`. Flags unsupported patterns (useState, useEffect, async calculateMetadata, third-party React libs, `@remotion/lambda`) and recommends runtime interop over lossy translation. Unsure whether to port vs. build fresh, or only a passing Remotion mention? → /hyperframes.

9018/mychat

Animate SVG character rigs with GSAP, CSS transforms, Remotion frame control, and HyperFrames-compatible browser previews.

9018/mychat

Three.js animation - keyframe animation, skeletal animation, morph targets, animation mixing. Use when animating objects, playing GLTF animations, creating procedural motion, or blending animations.

9018/mychat

Download video and audio from YouTube and 1000+ sites using yt-dlp. No API keys needed. Use when: (1) Downloading a video from YouTube or other sites, (2) Extracting audio from a video URL, (3) Downloading subtitles/captions from a video, (4) Getting video metadata without downloading.
