Ask HN-style: how to get gradient (differential diffusion) masks working in video models
Intrepid-Ground5004 · reddit · 2026-08-31
The user wants a black-and-white gradient mask for smooth transitions in video generation: black pixels = denoise 0, white = denoise 1, like differential diffusion. But in ComfyUI with set latent noise mask and a static gradient, the mask behaves binary — a hard cut between inpainted and original pixels. No solution given in the post.
