ComfyUI-MiniMaxH3-TemporalWindow-SpatialTiles enables 4K video generation without OOM errors

By PulseAugur Editorial · [1 sources] ·

A user has modified a Stable Diffusion workflow to incorporate ComfyUI-MiniMaxH3-TemporalWindow-SpatialTiles, enabling the generation of 4K resolution videos in approximately two hours. This modified workflow reportedly operates without encountering Out-of-Memory (OOM) errors, even on systems with 16GB of VRAM and 32GB of RAM. The user shared a pastebin link to the workflow and detailed the model's preparation for dynamic VRAM loading and its use of mixed precision operations. AI

IMPACT This modification demonstrates efficient resource utilization for AI video generation, potentially enabling higher-resolution outputs on consumer hardware.
