MiniMax H3 in ComfyUI: Motion Director for Longer Videos on RTX 3090

We tested Motion Director on RTX 3090 to get past MiniMax H3's length limit: 3 chained 5s segments in one 15s clip. Pure I2V vs. Ref2VA with a character sheet.

24GB VRAM (RTX 3090) -- real peak 23.4GB (I2V) and 22.84GB (Ref2VA), both with tight headroom

MiniMax H3 in ComfyUI: Real Face Swap with Ref2VA on RTX 3090

We verified MiniMax H3 face swap (RTX 3090) twice: with the creator's own assets and with a 100% self-generated video. The title's 'body swap' isn't shown.

24GB VRAM (RTX 3090) -- real peak 23.2GB with the REF2VA INT8 checkpoint, tight headroom

24GB VRAM (RTX 3090) -- real peak 23.53GB with the hybrid trick, 23.27GB with pure PDD Acc

24GB VRAM (RTX 3090 or equivalent) for the Wan stage, plus a separate Docker environment with GPU passthrough for the point-cloud render stage
