* docs(registry,skills): surface code-highlight 0-based indexing and opacity-reveal sweep guidance From the 2026-07-14 CLI feedback digest (skills-owner action): a user building code teaching videos hit two authoring gaps. 1. code-highlight's `line` is intentionally zero-based (`line: 1` = second displayed line) but the warning lived only in pr-to-video's code-vocabulary reference — nowhere an author actually touches the value. Call it out at the block-use sites: the `__BLOCK` declaration itself, the registry-item description, and the motion-graphics catalog map. 2. Opacity-only code-typing tripped `sweep_static` for that user, who worked around it with a slow host y-drift. The sweep fingerprint does include per-element opacity, so document the actual trap (a reveal that settles before the sampled window, then holds a static frame) and the idiomatic fixes (spread the reveal / keep a blinking caret alive) in the check reference — and pin the fingerprint's opacity sensitivity with a regression test covering both the visibility-floor crossing and a mid-fade value change. * docs(catalog): regenerate code-highlight page from updated registry-item description Only the code-highlight page is committed: a full generate-catalog-pages run also surfaces ~34 blocks missing from the git-tracked catalog index (pre-existing drift on main), which belongs in its own chore PR.
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
