Hyperframes CLI

HyperFrames CLI — Dev Loop

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. Visual inspect — npx hyperframes inspect
5. Preview — npx hyperframes preview
6. Render — npx hyperframes render

Lint and inspect before preview. Render before delivery.

Scaffolding

npx hyperframes init my-video                        # interactive wizard
npx hyperframes init my-video --example warm-grain   # pick a template
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 --example blank --tailwind # with Tailwind v4
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).

Visual Inspect

npx hyperframes inspect                 # inspect layout over the timeline
npx hyperframes inspect ./my-project    # specific project
npx hyperframes inspect --json          # agent-readable findings
npx hyperframes inspect --samples 15    # denser timeline sweep
npx hyperframes inspect --at 1.5,4,7.25 # explicit hero-frame timestamps

Reports:

• Text extending outside visual containers/bubbles
• Text clipped by fixed-width/fixed-height boxes
• Text extending outside the composition canvas
• Children escaping clipping containers

Error: must fix before rendering. Warning: agent review. Run with --strict to fail on warnings too.

Mark elements with data-layout-allow-overflow (intentional entrance/exit overflow) or data-layout-ignore (decorative elements).

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 browser automatically.

When handing a project back, use the Studio URL: http://localhost:<port>/#project/<project-name>

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

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

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.

Other Commands

npx hyperframes compositions   # list compositions in project
npx hyperframes docs           # open documentation
npx hyperframes benchmark .    # benchmark render performance
