* feat(studio): add per-composition render button in compositions tab Thread composition path through the full render pipeline so individual compositions can be rendered independently from the studio UI. - Add download icon button on each comp card (visible on hover) - Accept `composition` field in POST /projects/:id/render - Pass composition as `entryFile` to the producer's createRenderJob - Make the Export button in the Renders panel composition-aware (renders the active composition instead of always index.html) * fix(studio): make composition render buttons always visible The hover-only opacity made them undiscoverable. * fix(studio): address PR review — CLI adapter, path guard, a11y, tests, settings sync - Wire `composition` → `entryFile` in CLI studio adapter (studioServer.ts) so `hyperframes preview` renders the correct composition, not always index.html - Add path-traversal guard: reject composition paths that resolve outside projectDir - Add `aria-label` to the icon-only render button for screen readers - Add 4 tests: forwarding, empty/missing → undefined, path-traversal → 400 - Persist render settings (format/quality/fps) to localStorage so comp card buttons use the same settings as the Export panel * refactor(studio): extract render settings persistence to own module Move getPersistedRenderSettings/persistRenderSettings out of RenderQueue.tsx into renderSettings.ts so code-splitting the component doesn't drag along the helper.
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

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

npx hyperframes compositions
benchmark
