Video expander or video extender: wider picture or a longer video?

Updated · AI Video Expand

An expander, also called video outpainting or uncrop, makes the picture wider or taller: a 9:16 clip becomes 16:9, same length. An extender continues the video in time: an 8-second clip becomes 12 seconds, same shape. AI Video Expand is an expander; it doesn't add seconds.

How expanding works

Video outpainting is image outpainting (Photoshop's Generative Expand, DALL-E's uncrop) done on every frame of a video, so the new edges move with the camera and stay the same from frame to frame. Editors used to fill the gap with a blurred, zoomed copy of the clip or plain bars; AI video models can now draw the room, sky or street that the camera didn't catch.
