Robust Video Matting — Side-by-Side (RGB | Alpha)

Upload a video. Each output frame is the original RGB frame (left) stitched with RVM's predicted alpha mask (right), producing a 2W x H MP4.

Quality tips: keep downsample ratio = auto (it enables RVM's trained guided-filter refiner and keeps the network in-distribution at ~512px). Use resnet50 for the best edges; mobilenetv3 for speed. Set ref_size to 512 (default) or up to ~720 for a bit more detail on HD clips.
