Blur Video Background FAQ
How do I blur the background of a video?
Add the video here and press Remove background with Blur selected. The AI keeps the person sharp in every frame and softens the rest.
Can I replace the background instead of blurring it?
Yes. Switch to green screen, a colour or your own picture, or keep it transparent, at any time before exporting.
Does the blur follow the person when they move?
Yes. The cut-out is made for every frame, and Anti-flicker keeps the edge steady.
Is my video uploaded?
No. Everything runs in your browser and the video never leaves your device.
