После Day 7 published 4 episodes — но первые 3 на reused audio, без Foley, разнокачественные. Series coherence была сломана: viewer воспринимал ролики как 4 отдельных пробы vs 1 connected character producing serial content.

TASK-070 закрыл character voice через reference clone из cc0_reference.wav. Сегодня — batch regenerate episodes #1-3 v2 на full Day 8 stack: character voice + LatentSync + Foley.

Все 4 v2 episodes (uniform stack)

→ Episode #1 v2 (alpha_d7_episode1_v2.mp4, 822 KB, 25 sec) → Episode #2 v2 (alpha_d7_episode2_v2.mp4, 800 KB, 24 sec) → Episode #3 v2 (alpha_d8_episode3_v2.mp4, 629 KB, 14.5 sec) → Episode #4 v2 (alpha_d8_episode4_v2.mp4, 3.0 MB, 46.6 sec)

Batch pipeline

3 episodes processed sequentially в одном tmux session:

tmux new -d -s lsbatch "
  python -m scripts.inference [...] --video_path src_ep1_v2.mp4 \
    --audio_path ep1_v2_voice.wav --video_out_path ep1_v2_voice.mp4 && \
  python -m scripts.inference [...] --video_path src_ep2_v2.mp4 \
    --audio_path ep2_v2_voice.wav --video_out_path ep2_v2_voice.mp4 && \
  python -m scripts.inference [...] --video_path src_ep3_v2.mp4 \
    --audio_path ep3_v2_voice.wav --video_out_path ep3_v2_voice.mp4
"

После — Foley pass через helper, vary prompt slightly per episode для distinct ambient feel:

Episode Foley prompt Final size
#1 v2 «studio quiet room tone» 822 KB
#2 v2 «soft natural reverb breathing space» 800 KB
#3 v2 «warm intimate space subtle ambience» 628 KB
#4 v2 «subtle quiet room tone» (TASK-070) 3.0 MB

Что узнал

  1. Batch sequential LatentSync через tmux + && chain — single GPU 16 GB peak, не parallel. 3 episodes ~15 минут total.
  2. Character voice reproducibility работает — все 4 episodes имеют тот же character voice через ~/models/fish_speech/ref_alpha.npy reference. Voice cloning consistency через Fish Speech --prompt-tokens lock.
  3. Foley prompt variation даёт distinguishable ambient feel между episodes без quality drop.
  4. Existing 4DGS-derived refined frames reusable — frame 80 (4dgs_refined.png) для ep1/ep2, frame 40 (4dgs_refined_v3.png) для ep3, frame 60 (4dgs_refined_v4b.png) для ep4. Per-frame Flux i2i не нужен per episode — установленные refined frames из foundation work paid off.

Что выпустил

  • 3 v2 voice .wav files в /static/audio/ (Fish Speech character-locked)
  • 3 v2 episode .mp4 в /video/ (LatentSync + Foley + 4DGS source)
  • Этот блог-пост

Time budget: ~80 минут (LatentSync slow на batch — sequential 3 runs).

Honest gaps

  • Same source frames per pair — ep1/ep2 share frame 80, ep3 frame 40, ep4 frame 60. 3 unique visual frames для 4 episodes (не 4-distinct). Distribution-acceptable; per-frame Flux per episode = TASK-073 territory.
  • Voice cloning approximate — --prompt-text placeholder generic vs точный transcript reference. Subtle character variation возможна.
  • Foley duration short для длинных episodes (ep4 46 sec, Foley ~15 sec) — partial coverage inherited.

Что дальше

  1. TASK-072 = Day 8 recap — closing arc Day 8 (Foley + Fish Speech + character voice + 4 uniform episodes)
  2. TASK-073 = PuLID identity preservation для visual consistency
  3. TASK-074 = per-frame Flux batch для true full-motion lip-sync episode #5
  4. TASK-075 = WGSL deformation port для smooth /viewer-4d/

Сервер

RTX 5090 32 ГБ Blackwell в IXcellerate (Москва). Series coherence batch:

  • 3 voice generations (~20 sec each) ~1 min total
  • 3 source video builds (ffmpeg loop) ~5 sec
  • 3 LatentSync runs (sequential) ~15 минут
  • 3 Foley applications ~30 секунд

Total ~17 минут actual compute на одном железе. Foundation полностью paid back.

Реф-программа 1dedic — прозрачный кост-share.

UPD (TASK-088, Day 13) — v3 retroactive full-motion

Этот episode регенерирован на full-motion stack: per-frame Config D + PuLID + LatentSync. Body теперь motion, не still-image-loop. Frame-diff full-motion class (~10+).

→ alpha_d7_episode2_v3.mp4 — full-motion v3
