Reproducible Editorial Workflow Example
Use this example to prove that the FFmpeg skill artifacts compose from intake through acceptance. It generates synthetic media only; it does not authorize work on user media and it does not establish editorial quality or destination compatibility.
Run the example
From the ffmpeg skill directory, choose a new or empty task-local directory:
scripts/editorial-workflow-example /tmp/ffmpeg-editorial-example --json
The helper refuses a non-empty workspace and uses -n for every generated media artifact. It creates a short testsrc2 video with an 880 Hz synthetic audio track, then performs this complete path:
generate -> probe/intake -> bounded evidence -> EDL -> decoded trim
-> output probe/decode -> frame/audio checks -> acceptance
The example requires locally installed ffmpeg and ffprobe. It accepts --ffmpeg and --ffprobe paths and bounds source duration and per-command runtime.
Artifact closure
Every durable record uses workflow_id: synthetic-editorial-example; the source is asset-synthetic-001, and the bounded trim is event-001.

What the result proves
A successful run proves that the recorded local FFmpeg/FFprobe build completed this synthetic workflow, the output decoded, required streams were present, duration met tolerance, bounded frames were extracted, and the audio processing path completed.
It does not prove semantic visual correctness, listening quality, accessibility, rights, or compatibility with any player, editor, host, archive, or upload API. The acceptance report must retain those items as UNVERIFIED until the appropriate reviewer or destination supplies evidence.
Do not commit generated media or task-local evidence. Preserve the report package with the task when it is being used as release evidence.
