What is Rotoscoping?
The frame-by-frame process of isolating subjects from their backgrounds. AI now automates what was previously one of the most time-consuming post-production tasks.
How it works
Rotoscoping traces the outline of subjects frame by frame to separate them from their background. Traditional rotoscoping is extremely labor-intensive. AI-powered rotoscoping uses segmentation models to automate this process, reducing days of work to minutes. In AI video production, automated rotoscoping enables compositing AI-generated elements with real footage, replacing backgrounds in generated content, and creating layered compositions. The quality of AI rotoscoping has improved dramatically, though complex edges (hair, transparent objects, motion blur) still sometimes require manual cleanup.
