The Roto Brush has been overhauled using Adobe Firefly’s video models. In v25.U1, the AI can now track occluded objects (e.g., a hand passing behind a head) and automatically refine edges on hair and transparent objects.
To prove the upgrade is worth it, we ran tests on a standard workstation (RTX 4070, 64GB RAM, Ryzen 9 7950X).
