MaskVidExperiments: ComfyUI nodes for video masks

drozbay released a custom node pack, MaskVidExperiments (GPL-3.0), for ComfyUI: stable cropping around a moving object, precise reinsertion into the frame with a soft edge, noise and flicker cleanup from video masks, and conversion of masks to latent resolution via VAE, with support for chunked models MiniMax H3 and LTX-2.

🛠 MaskVidExperiments: ComfyUI nodes for video masks

drozbay released a pack of custom nodes (GPL-3.0) for video masks in ComfyUI: stable cropping around a moving object (Subject Crop), reinsertion with a soft edge (Subject Uncrop), noise and flicker cleanup (Mask Cleanup), and conversion of masks to latent resolution via VAE (Mask To Latent Space).

🌍 Naive cropping around a moving object jitters, and video models interpret this jitter as camera movement — this breaks inpainting. The pack plans the crop for the entire clip and converts masks to latent resolution via VAE, including chunked MiniMax H3 and LTX-2 with audio latent.

👤 If you are doing video inpainting in ComfyUI — object replacement, removal of a person or item — the pack removes the jerky crop and seams when reinserting. Installation: git clone into custom_nodes, requires ComfyUI v0.15.0+, no third-party dependencies.
