Open-source character replacement tests

Same source performance + character references · Modal GPU tests.
Pixel-preserving head swap — GHOST 2.0

Original frame 1

GHOST 2.0 frame 1

Real body, hands, room and camera pixels preserved. The original green cap still leaks behind the new bob, so we need an occlusion/removal pass.

Original frame 2

GHOST 2.0 frame 2

Same pixel-preserving route; again the source cap remains outside the replacement matte.

Latest realism experiments

MoCha → SeedVR2 restoration

720×1264. Sharper skin/hair/fabric and cleaner camera texture; underlying generated-human geometry is still visible.

MoCha HQ — 30 steps / no distillation

~34 min for 2.7s. More expensive, not a clear realism improvement.

HunyuanCustom — 50-step editing

More photographic texture, but body/clothing geometry breaks on this performance.

MoCha structural tests

MoCha — 161-frame

Best structural replacement, still synthetic looking.

MoCha — 81-frame

MoCha — later chunk 2

MoCha — later chunk 3
