About this Pixelflow
What is Change the Background of a Video?
Change the Background of a Video moves the person in your clip to a new place without a green screen. Describe the place in a sentence and get the same take back: their face, hair, gestures and lip movement stay, and the light on them changes to match. Made with Gemini 3.8 Flash and Gemini Omni 1.2 Flash for creators, brands and video teams.

Change the Background of a Video FAQ
Building with it? Read the Change the Background of a Video API docs.
Do I need a green screen?
No. Any clip with the person clearly in view works, and the edges, hair included, are handled for you.
Does the light on the person change?
Yes. The light on the face, hair and clothes is matched to the new place, so a sunset scene puts warm light on them.
Why was my clip refused?
Clips that show real brand logos, packaging or posters can be refused by the video model’s copyright filter, and the edit is not billed when that happens. Use footage without visible brands.
Can I run it from my own code?
Yes. It runs through the Pixelflow API with the same inputs: submit a run, then poll for the result.
