Netflix has open-sourced VOID (Video Object and Interaction Deletion), a model that removes objects from video while cleaning up the physics those objects leave behind. It is the first public AI model Netflix has ever released, and it points directly at how the company is thinking about AI-assisted post-production.
VOID is not a general-purpose generative video tool. It solves a specific, persistent problem in VFX and editing: when you remove something from a shot, you also need to remove everything that thing was doing to the scene. Shadows, reflections, motion blur, surface contact, collision effects. Existing tools handle the paint-out but leave the physics intact, which means manual cleanup or uncanny artifacts. VOID targets that gap.
How It Works
The model operates in two phases. First, a vision-language model analyzes the scene to identify regions causally affected by the object being removed. If a ball is bouncing off a surface, the model identifies the compression point, the trajectory distortion of nearby objects, the shadow path. These regions get encoded into what the team calls a "quadmask," which then guides a video diffusion model to generate a physically plausible version of the scene where the object was never there. The technical details are laid out in the arXiv paper.
The second phase handles shape stability. When the first pass introduces geometric distortion on remaining objects, a refinement step uses flow-warped noise from the initial generation to lock down object geometry along corrected trajectories. The result is a clean removal that holds up across frames without the wobble or smearing that plagues current inpainting methods.
