About

Last updated November 10, 2026

AI Video Expand is a small independent product. Phone videos are tall and most other screens are wide, and the usual fixes (black bars, a blurred copy behind, or cropping) all look like a fix. So we built a tool that keeps the whole clip and lets AI fill in the missing sides, in the browser.

How it works

Your clip is sent to an AI video model, LTX 2.3 from Lightricks, run by our API provider fal.ai. It keeps every frame of your original and its sound, and generates the edges the new shape needs, in the quality you pick.

What we won't do

• Expand sexual content, or clips you have no right to edit.
• Make sexual or misleading content.
• Use your clips to train models or keep them longer than 30 days.
