ComfyUI ControlNet Video Builder with Masking

Introducing ComfyUI ControlNet Video Builder with Masking for quickly and easily turning any video input into portable, transferable, and manageable ControlNet Videos. Including the most useful ControlNet pre-processors for vid2vid and animate diffusion, you have instant access to Open Pose, Line Art, Depth Map, and Soft Edge ControlNet video outputs with and without background or actor thanks to COCO Segmenter colour masking. In addition to masked ControlNet video's you can output masked video composites, with the included example using Soft Edge over RAW.

This workflow uses multiple custom nodes, it is recommended you install these using ComfyUI Manager. Output videos can be loaded into ControlNet applicators and stackers using Load Video nodes. Includes project naming for managing project save location.
