Change the aspect ratio of any clip without cropping. The original picture stays as it is, and new surroundings are generated around it to fill the new frame.

Why use the video expander?

1

Ten frame options

Pick 16:9, 9:16, 1:1, 4:3, 3:4, 3:2, 2:3, 21:9 or 9:21, or let Auto choose a suitable frame for your video.

2

Nothing gets cropped

Your subject, motion and framing stay intact. Only the new areas around the original picture are created.

3

Per-second pricing

8 credits per second, with a 3-second minimum. Clips up to 60 seconds are supported.
