Why ComfyUI Video Workflows Ignore Disk-Offloading & Context Windows
Acceptable-Work8202 · reddit · 2026-08-31
Author discusses the VRAM bottleneck in ComfyUI video generation, where entire video tensors stay in memory. They propose a context window approach: generating frames one by one, offloading them to disk, and reloading only the last frame for the next step. This 'disk-offloading + context window' method would keep VRAM flat, enabling long-form video generation on lower-end hardware.
