Endless MiniMax H3 v1.6: ComfyUI workflow for unlimited-length lip-synced video on 12GB
embryo10 · reddit · 2026-10-12
The Endless MiniMax H3 (with Endless LipSync) v1.6 ComfyUI workflow stitches Motion Context clips into unlimited-duration lip-synced videos with no visible seams, via the H3-Motion-Context node and a custom Clip Stitcher. On an RTX 3060 12GB it produces a 90-second synced video in 2 hours. Key points:
- Supports T2V/I2V (FL2AV) and Ref2AV; latents are saved/loaded so any clip can be regenerated (later clips fuse with the replaced one)
- New Clip Refiner group in v1.6 largely fixes overexposure/over-contrast degradation when stitching clips without camera cuts
- Redesigned config panel and subgraphs for newer ComfyUI front-end, fixing the reset-after-refresh bug
