New ComfyUI nodes let you mask any video area and insert characters
roychodraws · reddit · 2026-09-23
The author updated their open-source ComfyUI video editing workflow (V6) with two new nodes: an upload-mask node that accepts masks made in external tools like After Effects, and a mask-creation node for selecting any region directly inside ComfyUI. With masking in place, users can modify targeted areas of a video or insert characters into empty space in existing footage. The workflow is available on GitHub (roycho87/minimaxwf), with a demo video showing a character inserted into a chess tournament scene.
