Netflix open-sources VOID, an AI framework that erases video objects and rewrites the physics they left behind

Netflix open-sourced VOID, an AI system that removes objects from videos and fixes the resulting physical effects.

VOID uses Alibaba's CogVideoX as a backbone and was fine-tuned with synthetic data from Google's Kubric and Adobe's HUMOTO.

Google's Gemini 3 Pro and Meta's SAM2 are used for scene analysis and object segmentation, and an optional optical-flow pass corrects shape distortions.

The project was developed with INSAIT Sofia University and is released under the Apache 2.0 license with code and demos public.
