Recreating TikTok's viral character-swap videos locally with MiniMax in ComfyUI at 250s per shot
r_panthon · reddit · 2026-10-16
Reddit user rpanthon shares a full workflow for recreating TikTok's viral character-swap dance videos (originally made with Claude + Seedance 2.5) locally using MiniMax in ComfyUI.
Key details
- Uses the default ref2va template plus the MiniMax-H3-Character-Swap-LoRA from HuggingFace, which the author says transfers motion more accurately than Liveportrait-style methods
- Works shot by shot (multi-shot generations fail); 352x640, 8 steps with the turbo 8-step LoRA, 250s per shot on a 4090
- Generates a single guiding frame first via the Qwen 2.1 edit template
- Critical gotcha: force the loaded video to 24 fps or results desync and glitch
They also vibecoded a custom node that pulls a video from TikTok/YouTube and prepares a trimmed reference with a timeline UI. Quality isn't Seedance-level, but it runs fully local.
