description: 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.

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

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

npx hyperframes lint                  # current directory
npx hyperframes lint ./my-project     # specific project
npx hyperframes lint --verbose        # info-level findings
npx hyperframes lint --json           # machine-readable

Lints `index.html` and all files in `compositions/`. Reports errors (must fix), warnings (should fix), and info (with `--verbose`).

Previewing

npx hyperframes preview                   # serve current directory
npx hyperframes preview --port 4567       # custom port (default 3002)

Hot-reloads on file changes. Opens the studio in your browser automatically.

Rendering

npx hyperframes render                                # standard MP4
npx hyperframes render --output final.mp4             # named output
npx hyperframes render --quality draft                # fast iteration
npx hyperframes render --fps 60 --quality high        # final delivery
npx hyperframes render --format webm                  # transparent WebM
npx hyperframes render --docker                       # byte-identical

| Flag | Options | Default | Notes | | -------------- | --------------------- | -------------------------- | --------------------------- | | `--output` | path | renders/name_timestamp.mp4 | Output path | | `--fps` | 24, 30, 60 | 30 | 60fps doubles render time | | `--quality` | draft, standard, high | standard | draft for iterating | | `--format` | mp4, webm | mp4 | WebM supports transparency | | `--workers` | 1-8 or auto | auto | Each spawns Chrome | | `--docker` | flag | off | Reproducible output | | `--gpu` | flag | off | GPU-accelerated encoding | | `--strict` | flag | off | Fail on lint errors | | `--strict-all` | flag | off | Fail on errors AND warnings |

**Quality guidance:** `draft` while iterating, `standard` for review, `high` for final delivery.

Transcription

npx hyperframes transcribe audio.mp3
npx hyperframes transcribe video.mp4 --model medium.en --language en
npx hyperframes transcribe subtitles.srt   # import existing
npx hyperframes transcribe subtitles.vtt
npx hyperframes transcribe openai-response.json

Text-to-Speech

npx hyperframes tts "Text here" --voice af_nova --output narration.wav
npx hyperframes tts script.txt --voice bf_emma
npx hyperframes tts --list  # show all voices

Troubleshooting

npx hyperframes doctor       # check environment (Chrome, FFmpeg, Node, memory)
npx hyperframes browser      # manage bundled Chrome
npx hyperframes info         # version and environment details
npx hyperframes upgrade      # check for updates

Run `doctor` first if rendering fails. Common issues: missing FFmpeg, missing Chrome, low memory.
