Freeze the source and every processing branch
Register the original H3 file with a stable identifier and hash, then capture frame size, frame rate, duration, codec, bitrate, color information, audio layout, generation context, and rights status. Create a separate branch for each processor or provider path. Record product name, version, date, account or region context, input handling, preset, scale, denoise, sharpening, interpolation, face reconstruction, grain, output format, and every hidden default that can be observed. Never overwrite the source or allow one branch to consume another branch's processed file unless that sequence is the declared test.
- Immutable source record
- One identifier per branch
- Exact visible settings
- Common final delivery specification

Build matched crops and motion checks
Choose representative time ranges before seeing the processed results: a face or hand, a fine repeating pattern, readable text if present, a high-motion edge, a gradient, a particle or texture region, and a cut. Export frame crops from the same coordinates and inspect the complete clips at normal speed, slow playback, and frame stepping. Use artifact codes for halo, ringing, crawling detail, flicker, line wobble, identity change, false texture, smoothing, color shift, dropped audio, cadence change, and compression. Notes should describe observable differences rather than infer detail recovery.

Close with a delivery-specific disposition
Assign pass, fail, or needs-review status to each declared criterion and name the responsible reviewer. Record output size, processing duration, and charged cost only when the same dated run exposes them directly. Compare the chosen result with the unprocessed delivery baseline, because additional pixels may not improve the actual destination after resizing or recompression. State which branch was selected, what artifacts remain, what editorial repair is required, and what change would trigger a new test. The packet supports a local decision; it does not certify model or vendor performance.
