#2740 added `--` to one of nine independent ffprobe invocations, so the bug class it closed stayed open everywhere else while CI reported it fixed — the regression test asserts the argv of that single site. Reproduced on ffprobe 8.1.1: an asset named `-intro.mp4` probes fine through extractMediaMetadata but fails with "Missing argument for option 'intro.mp4'" in audio pad/trim (mid-render), `hyperframes init`, whisper duration probing and webmAlphaCheck. hevcPreviewLint catches and returns false, so a dash-prefixed HEVC preview silently passes the lint rule. Terminated at all of them: producer/services/render/audioPadTrim.ts (x2) producer/plan-parity-analysis.ts cli/commands/init.ts cli/utils/webmAlphaCheck.ts cli/whisper/transcribe.ts (x2) core/mediaGradeAnalyzer.ts lint/hevcPreviewLint.ts audioPadTrim's runFfprobeJson is a near-verbatim clone of the engine's runFfprobe and structurally cannot add the terminator itself, because callers bake the input path into `args`. It now asserts the terminator is present rather than letting a dash-prefixed path through, takes the same stdio ["ignore", ...] as the engine helper, and redacts its stderr — it was throwing raw ffprobe output, which echoes the input path, into logs and telemetry.

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
