Wild report (5th in cluster, CLI 0.7.53): snapshots omitted all text while check passed — text painting with a transparent -webkit-text-fill-color (which overrides `color` for the glyph fill AND inherits, so a parent's transparent fill silently blanks descendant text that has its own opaque `color`) renders invisible, but every geometry/occlusion/contrast audit missed it. Contrast in particular reads `color`, not the fill that actually paints, so white-`color` + transparent-fill text scored as high-contrast and passed. Add an invisible-text detector to the layout audit: flag any text element whose effective fill (computed -webkit-text-fill-color, which already resolves to `color` when unset) is transparent. Gradient/clipped text (background-clip:text) legitimately uses a transparent fill and is excluded. Verified: check now fails on an inherited-transparent-fill fixture (text_not_painted) while gradient text, body-inherited color, sub-composition color, and real registry examples stay clean.
hyperframes
CLI for creating, previewing, and rendering HTML video compositions.
Install
npm install -g hyperframes
Or use directly with npx:
npx hyperframes <command>
Requirements: Node.js >= 22, FFmpeg
Commands
init
Scaffold a new Hyperframes project from a template:
npx hyperframes init my-video
cd my-video
preview
Start the live preview studio in your browser:
npx hyperframes preview
# Studio running at http://localhost:3002
npx hyperframes preview --port 4567
render
Render a composition to MP4. Run from the project directory; the positional
argument is the project directory (not a file), so render the project's
index.html directly, or point at a specific composition file with -c:
npx hyperframes render -o output.mp4
npx hyperframes render -c ./my-composition.html -o output.mp4
lint
Validate your Hyperframes HTML:
npx hyperframes lint ./my-composition
npx hyperframes lint ./my-composition --json # JSON output for CI/tooling
npx hyperframes lint ./my-composition --verbose # Include info-level findings
By default only errors and warnings are shown. Use --verbose to also display informational findings (e.g., external script dependency notices). Use --json for machine-readable output with errorCount, warningCount, infoCount, and a findings array.
compositions
List compositions found in the current project:
npx hyperframes compositions
benchmark
Run rendering benchmarks:
npx hyperframes benchmark ./my-composition.html
doctor
Check your environment for required dependencies (Chrome, FFmpeg, Node.js):
npx hyperframes doctor
browser
Manage the bundled Chrome/Chromium installation:
npx hyperframes browser
info
Print version and environment info:
npx hyperframes info
docs
Open the documentation in your browser:
npx hyperframes docs
upgrade
Check for updates and show upgrade instructions:
npx hyperframes upgrade
npx hyperframes upgrade --check --json # machine-readable for agents
