It's easy to use, the results are consistent, and I can get something polished without spending time fixing or redoing things. It fits naturally into how I create, which is why I keep coming back to it."

AI Video Expander FAQ
AI Video Expander enlarges the frame of your video using AI. Instead of cropping, stretching, or adding blurred borders, it generates new visual content around the original clip to fit a new aspect ratio.
No. AI Video Expander changes the size or aspect ratio of the video frame. AI Video Extender makes a video longer by generating additional footage at the end.
Video outpainting is the process of generating new visual content beyond the original edges of a video. It is similar to image outpainting, but applied across video frames so the expanded area stays consistent over time.
Yes. You can expand horizontal videos into vertical formats like 9:16 for TikTok, Instagram Reels, and YouTube Shorts.
Yes. You can expand portrait videos into 16:9 widescreen format for YouTube, ads, websites, and presentations.
No. The goal is to keep your original video visible while generating new surrounding content to fill the selected frame.
Usually, yes. Blurred backgrounds are fast, but they often look generic. AI Video Expander creates new visual context that better matches the original scene.
Videos with clear subjects, stable lighting, and consistent camera movement usually work best. Fast cuts, heavy motion blur, sudden scene changes, or very complex backgrounds may be harder to expand cleanly.
If prompt guidance is available, you can describe what the expanded area should look like. Otherwise, Magic Hour will automatically infer the surrounding scene from the original video.
