Rotoscoping traces a subject frame by frame so it can be composited onto a new background or edited separately. Video segmenters like SAM 2 automate the per-frame masking that artists used to draw manually, cutting hours of post-production work.
Definition
Cutting a moving subject out of every frame to isolate or replace it. Once painstaking by hand, now largely automated by video segmentation models.
