About AI Video Expander
AI Video Expander extends the scene beyond an existing video frame. Our focus is helping creators adapt footage to a different aspect ratio while keeping the original subject in view.
More room around your video
The workflow starts with an existing clip and a target frame. AI video outpainting adds surrounding visual content so footage can be adapted for vertical, square, or widescreen formats without relying on a crop or black bars.
