## In short

Netflix's first open-source AI model removes objects from video and rewrites the physics of the scene — if you delete a person holding a guitar, the guitar falls naturally. Apache 2.0 licensed.

## What it is

VOID (Video Object and Interaction Deletion) is Netflix Research's first publicly released AI model. It does video inpainting — removing objects from video — but unlike prior tools that just fill in the background, VOID also handles the downstream physical consequences. Remove a person pushing a ball, and the ball stops moving. Remove someone holding a guitar, and the guitar drops.

## How it works

VOID uses a two-pass approach built on CogVideoX. First, a vision-language model identifies the causally affected regions of the scene — areas whose behavior would change if the target object were absent. Then a video diffusion model, fine-tuned on synthetic counterfactual data from Kubric and HUMOTO simulators, inpaints those regions with physically plausible outcomes. The second pass improves temporal consistency.

## Why it matters

Video editing tools today struggle with interaction-aware removal. Deleting a person typically leaves floating objects or frozen physics. VOID solves this by treating video editing as causal reasoning, not just pixel filling. Being open-source under Apache 2.0 means VFX teams and indie filmmakers can integrate it into existing pipelines.

## Who it's for

VFX artists, video editors, film production teams, computer vision researchers.
