Review feedback on #2411 (Rames): the crash-survival RenderCaptureObservability mirror passed deFallbackFailedDb raw/unrounded while the render_complete perfSummary path rounded to 1 decimal — the same underlying PSNR could ship two different values to PostHog depending on which event fired. Extracted the existing inline round/clamp expression (previously duplicated for verifyMinDb and fallbackFailedDb) into a shared roundDb helper, applied once at the single point deFallbackFailedDb is derived from the thrown error so both downstream consumers agree. Also threads verifyThresholdDb (captured on the error but never propagated, per the nit) through DrawElementPerfInput/RenderCaptureObservability/render.ts/ telemetry as de_fallback_threshold_db on both events — the HF_DE_VERIFY_MIN_DB value the failing dB breached, letting ops read "28.4dB failed a 32dB threshold" directly instead of cross-referencing config.
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
