The producer already supports `format: "png-sequence"` end-to-end (see RenderConfig in renderOrchestrator.ts), but the CLI's VALID_FORMAT validator rejects it before the flag reaches the producer. Surface it the same way `mov` and `webm` are surfaced. Behaviour: - `--format png-sequence` accepted alongside mp4/webm/mov. - Auto-output path uses no extension (FORMAT_EXT["png-sequence"] = "") since the producer treats outputPath as a directory of frame_NNNNNN.png. - `printRenderComplete` sums the contained file sizes when outputPath is a directory, instead of reporting the platform-dependent inode size. - DockerRenderOptions.format type extended; existing buildDockerRunArgs is unchanged because it forwards the string verbatim. Tests: - renderLocal forwards `format: "png-sequence"` to createRenderJob. - buildDockerRunArgs propagates `--format png-sequence` to the container. Docs: - Rendering guide: format flag table, format comparison table, new "PNG sequence (no encoding)" section, "How it works" extended. - CLI package docs: format flag table updated.
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:
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
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
