The arm64 render image had no pinned browser: chrome-for-testing publishes no linux-arm64 build, so Dockerfile.render fell back to Debian bookworm's rolling `chromium` package. Its current arm64 build (150.0.7871.46) SIGTRAPs at startup (exit 133), breaking `render --docker` 100% on Apple Silicon. Install a pinned, non-Debian chrome-headless-shell from Playwright on arm64 (Google's build, not Debian's repackage). The wrapper wires whichever binary landed into PRODUCER_HEADLESS_SHELL_PATH and now fails the build loudly if neither is present, instead of silently using the broken Debian chromium. Bonus: arm64 gains BeginFrame deterministic capture it previously lacked. amd64 path is unchanged. Verified on Apple Silicon: same arm64 image, Debian chromium 150 -> exit 133, Playwright arm64 headless-shell (Chromium 149) -> exit 0.
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:
npx hyperframes render ./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
