version: "1.0.0" name: video-technical-review description: Review a rendered video for technical defects such as resolution mismatch, missing or near-silent audio, black or white frames, edge gutters, low motion, sparse caption bands, and layout issue pass-through.

Video Technical Review

Use this after a video has been rendered and you need a deterministic technical audit before human or model review.

This skill owns:

• probing video resolution, duration, frame rate, and audio streams
• sampling frames for black/white frames, bright edges, black gutters, caption

band sparsity, and low-motion runs

• measuring audio volume when an audio stream exists
• preserving known issue codes from content-machine audit reports
• writing video-technical.report.json, contact-sheet.png, and

contact-sheet.metadata.json

Inputs

Required:

{
  "videoPath": "./output/example-run/output.mp4"
}

Optional fields:

• outputDir: directory for report artifacts; defaults next to the video.
• expectedWidth and expectedHeight: default to 1080 and 1920.
• expectAudio: emit missing-audio when no audio stream exists, default true.
• expectCaptions: check bottom caption band sparsity, default true.
• frameSampleCount: number of frames to sample, default 12.
• layoutReportPath: pass through issues whose codes begin with layout-.

Outputs

The result contains reportPath, report, contactSheetPath, contactSheetMetadataPath, and contactSheetMetadata. The report is written to video-technical.report.json.

Preserved issue codes:

• wrong-resolution
• missing-audio
• near-silent-audio
• white-flash-or-white-frame
• black-frame
• white-edge-artifact
• black-gutter-artifact
• low-motion-run
• caption-band-sparse
• layout-*

Interpretation Notes

The visual checks are sampled-frame heuristics. Treat them as triage evidence: they catch obvious render failures and artifact classes, but they do not replace watching the source video when a borderline issue matters.
