HyperFrames CLI tool — hyperframes init, lint, preview, render, transcribe, tts, doctor, browser, info, upgrade, compositions, docs, benchmark. Use when scaffolding a project, linting or validating compositions, previewing in the studio, rendering to video, transcribing audio, generating TTS, or troubleshooting the HyperFrames environment.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# HyperFrames CLI
Everything runs through `npx hyperframes`. Requires Node.js >= 22 and FFmpeg.
## Workflow
1. **Scaffold** — `npx hyperframes init my-video`
2. **Write** — author HTML composition (see the `hyperframes` skill)
3. **Lint** — `npx hyperframes lint`
4. **Preview** — `npx hyperframes preview`
5. **Render** — `npx hyperframes render`
Lint before preview — catches missing `data-composition-id`, overlapping tracks, unregistered timelines.
## Scaffolding
```bash
npx hyperframes init my-video # interactive wizard
npx hyperframes init my-video --example warm-grain # pick an example
npx hyperframes init my-video --video clip.mp4 # with video file
npx hyperframes init my-video --audio track.mp3 # with audio file
npx hyperframes init my-video --non-interactive # skip prompts (CI/agents)
```
Templates: `blank`, `warm-grain`, `play-mode`, `swiss-grid`, `vignelli`, `decision-tree`, `kinetic-type`, `product-promo`, `nyt-graph`.
`init` creates the right file structure, copies media, transcribes audio with Whisper, and installs AI coding skills. Use it instead of creating files by hand.
## Linting
```bash
…
The line at the top of this page pins the label v0.4.3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
A 17 of 17 checks passed. Fixed automatic checks with no AI involved, so the same checks give the same answer every run.
