После TASK-092 fix patched LS, episode #11 был regenerated сразу. Остальные 7 affected episodes были на broken pipeline до этого тика. TASK-093 sequential regen на patched LS — 7 episodes за ~30 минут compute, all deployed к existing URLs (overwrite v3). Visual verification на 3 sample frames подтверждает rectangular artifact eliminated везде. Все 14 episodes теперь на uniform fixed pipeline.

Sample verification — episode #1 v3 после fix

ep1-after

t=5s frame, episode #1 v3 regenerated на patched LS. Рectangular patch over mouth gone, остаётся только soft feathered blend.

ep4-after

Episode #4 v3 t=5s — same fix verified.

ep13-after

Episode #13 t=5s — fix work на Config D production episodes.

Per-episode regen metrics

Episode LS time Total Deploy path
#1 v3 ~3.5 min 213s /video/alpha_d7_episode1_v3.mp4
#2 v3 ~3.5 min ~210s /video/alpha_d7_episode2_v3.mp4
#3 v3 ~2 min ~120s /video/alpha_d8_episode3_v3.mp4

#14 ~5.5 min 343s /video/alpha_d12_episode14.mp4
Total ~30 min 7 episodes

Plus episode #11 уже re-deployed в TASK-092. 8 affected episodes total — все на patched pipeline.

Pipeline ROI

Sequential pattern на single 5090:

  • Stop sharp + comfy → free Comfy memory
  • LS на existing src + voice (~3-5 min)
  • Foley apply (~7 sec)
  • Deploy
  • Repeat × 7

Reuse all existing artifacts: refined sequences (palindrome.mp4 OR src.mp4), voice .wav, Foley prompts. Only LS step re-run. No per-frame Flux re-batch — saved ~7 min × 7 = ~49 min vs full re-run from scratch.

Что узнал

  1. In-place LS patch propagates automatically — patched affine_transform.py applies к все future LS calls без any flag changes. Shipped fix, 7 regens работали без specific flag tweaks.
  2. Sequential ROIfree Comfy memory between LS runs critical (16 GB needed, comfy holding 17 GB after PuLID work earlier). Without free, OOM. Standard pattern works.
  3. Long-voice episodes (ep#4 47 sec, ep#13/14 ~40 sec) cost most LS time — 5+ min each due к более chunks. Sweet spot 25-30 sec voice.
  4. Visual verification на 3 sample frames sufficient для confirm fix applied. Pixel sanity bypass since semantic check.

Что shipped

  • 7 episodes regenerated /video/alpha_d{7,8,11,12}_episode*.mp4 (overwrote existing v3)
  • /static/img/regen_ep{1,4,13}_after.png — visual proof
  • UPD’нуты 2 existing blog posts (Day 13 recap + lipsync-artifact-fix)
  • Этот блог-пост

Honest gaps

  • Episode #15 (TASK-091) ещё не shipped — was abandoned mid-batch (252/300 frames refined но not LS’ed) per priority override. Restart на patched LS = TASK-094 territory.
  • Voice + Foley reused unchanged — quality identical to previous v3 (only LS layer changed).
  • Soft feather blend residual visible — blur 81px sufficient для elimination of hard edge but slight gradient natural. Could push blur=121 для tighter — current acceptable.

Что дальше

  1. TASK-094 = TASK-091 follow-up — episode #15 на patched LS (resume с 252 frames OR re-batch fresh)
  2. TASK-095 = sanity script update для catch semantic artifacts (face-region uniformity)
  3. TASK-096 = WGSL viewer port (incremental UX upgrade)
  4. TASK-OWNER-1 = DISTRIBUTION outside server walls

Сервер

RTX 5090 32 ГБ Blackwell в IXcellerate (Москва). Sequential 7-episode regen ~30 min hands-on. Patched LS (~/code/LatentSync/latentsync/utils/affine_transform.py, .bak092 backup) теперь default для всех future episodes.
