Splits propertyPanelVstSection.tsx (816->429 lines) into propertyPanelVstShared.ts, propertyPanelVstCarveSection.tsx, and propertyPanelVstPluginRows.tsx; useVstHost.ts (673->356 lines) into vstHostWire.ts (protocol parsing, pending-request bookkeeping, socket connect sequence); useVstPreview.ts (806->397 lines) into useVstPreviewHelpers.ts (load-scan orchestration, track lifecycle, PCM decode). Decomposes timelineIframeHelpers.ts's flagged autoHealMissingCompositionIds and buildMissingCompositionElements. Dedupes parseIntFlag/parsePositiveInt/parseEnum and the sites-create verb guard shared by lambda.ts/cloudrun.ts into utils/distributedRenderFlags.ts, and the ffmpeg-timeout/output-dir/ result-building boilerplate shared by audioMixer.ts's extract/prepare/ silence helpers. Extracts shared test-render boilerplate (testRenderUtils.tsx) across the propertyPanelFlat*.test.tsx family and per-file test fixtures (vstSidecarTestFixture.ts, vstSocketTestFixture.ts) elsewhere. Also fixes two 600-line filesize-gate regressions introduced while reconciling this work against an updated origin/main: extracts removeBackgroundViaApi out of StudioRightPanel.tsx, and drops a dead re-export block from PropertyPanel.tsx (its only consumer already had the real source available directly). All of the above is pure extraction/dedup — no behavior change. Verified: fallow audit passes clean (0 introduced complexity/duplication/dead-code findings), full monorepo build succeeds, and the full test suite passes across studio/engine/cli/vst-host.

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
