Only consuming telemetry from one data point per install badly undersampled the "routed" (successful) outcome — the far more common case. Changed maybeConsumeDeParallelRouterTrial to only turn the trial off when the router's OWN safety net actually fired (deParallelRouter === "reverted"), not on a clean "routed" success. This runs the experiment on every eligible render for an install indefinitely until it hits one real failure, then stops for that install going forward — trading a slightly higher per-install ceiling on experimental-path exposure for dramatically more successful- routing telemetry volume across the fleet. Also fixed a related edge case while updating this: a render that merely "routed" (router fired, self-verify never even tripped) but then crashed for an unrelated reason (e.g. cancellation) no longer counts as a router failure — only "reverted" (the router's fallback path actually engaged) does. Cancelling a render isn't evidence the router is unsafe. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
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
