version: "1.0.1" name: hyperframes-cli 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
- Scaffold —
npx hyperframes init my-video - Write — author HTML composition (see the
hyperframesskill) - Lint —
npx hyperframes lint - Preview —
npx hyperframes preview - Render —
npx hyperframes render
Lint before preview — catches missing data-composition-id, overlapping tracks, unregistered timelines.
Scaffolding
npx hyperframes init my-video # interactive wizardnpx hyperframes init my-video --example warm-grain # pick an examplenpx hyperframes init my-video --video clip.mp4 # with video filenpx hyperframes init my-video --audio track.mp3 # with audio filenpx 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 directorynpx hyperframes lint ./my-project # specific projectnpx hyperframes lint --verbose # info-level findingsnpx 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 directorynpx 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 MP4npx hyperframes render --output final.mp4 # named outputnpx hyperframes render --quality draft # fast iterationnpx hyperframes render --fps 60 --quality high # final deliverynpx hyperframes render --format webm # transparent WebMnpx 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.mp3npx hyperframes transcribe video.mp4 --model medium.en --language ennpx hyperframes transcribe subtitles.srt # import existingnpx hyperframes transcribe subtitles.vttnpx hyperframes transcribe openai-response.json
Text-to-Speech
npx hyperframes tts "Text here" --voice af_nova --output narration.wavnpx hyperframes tts script.txt --voice bf_emmanpx hyperframes tts --list # show all voices
Troubleshooting
npx hyperframes doctor # check environment (Chrome, FFmpeg, Node, memory)npx hyperframes browser # manage bundled Chromenpx hyperframes info # version and environment detailsnpx hyperframes upgrade # check for updates
Run doctor first if rendering fails. Common issues: missing FFmpeg, missing Chrome, low memory.
