A user encountered severe jitter artifacts when running the MiniMax H3 video generation model locally in ComfyUI.
Running on an RTX 4070 SUPER (12GB VRAM) and 64GB RAM, the user tried both default and custom workflows, along with various quantization methods like Sage Attention, int8, and w4a8, but the issue persisted. While previous reports suggested the model could run on 8-12GB VRAM using offloading, the poster is asking the community for troubleshooting advice.
