hyperframes

A system that turns animated HTML, CSS and JavaScript compositions into MP4 or WebM video files. HTML describes the scenes, timing and appearance, while FFmpeg encodes the result.

In plain words
What is it for?
Use it for motion graphics, product tours, captioned narration, social-media overlays, animated titles, audio-reactive visuals and website-to-video projects.
Why use it?
It lets browser-based animations become deterministic video files instead of remaining interactive webpages.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

hyperframes scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/setup.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 209 lines — stays where its author put it; the contents beside it link to each section on GitHub.

HyperFrames

HTML is the source of truth for video. A composition is an HTML file with data-* attributes for timing, a GSAP timeline for animation, and CSS for appearance. The HyperFrames engine captures the page frame-by-frame and encodes to MP4/WebM with FFmpeg.

Complement to manim-video: Use manim-video for mathematical/geometric explainers (equations, 3B1B-style). Use hyperframes for motion-graphics, talking-head with captions, product tours, social overlays, shader transitions, and anything driven by real video/audio media.

When to Use

  • User asks for a rendered video from text, a script, or a website
  • Animated title cards, lower thirds, or typographic intros
  • Captioned narration video (TTS + captions synced to waveform)
  • Audio-reactive visuals (beat sync, spectrum bars, pulsing glow)
  • Scene-to-scene transitions (crossfade, wipe, shader warp, flash-through-white)
  • Social overlays (Instagram/TikTok/YouTube style)
  • Website-to-video pipeline (capture a URL, produce a promo)
  • Any HTML/CSS/JS animation that must render deterministically to a video file

Do not use this skill for:

  • Pure math/equation animation (→ manim-video)
  • Image generation or memes (→ meme-generation, image models)
  • Live video conferencing or streaming

Quick Reference

npx hyperframes init my-video               # scaffold a project
cd my-video
npx hyperframes lint                        # validate before preview/render
npx hyperframes preview                     # live-reload preview (long-lived server, port 3002)
npx hyperframes render --output final.mp4   # render to MP4
npx hyperframes doctor                      # diagnose environment issues

preview is a long-lived Next.js server that holds Chrome render workers open. Always stop it when done (see Cleanup) — a forgotten preview keeps idle chrome-headless-shell workers alive that, on GPU-less hosts (WSL, containers, CI), spin a CPU core each indefinitely via software WebGL (swiftshader).

What ships with it

7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

hyperframes is a skill published in the GitHub repository NousResearch/hermes-agent (238,457 stars, last pushed yesterday), licensed MIT. It adds 13 tokens to every session and 3,817 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
