VideoExpander - AI video expander for uncropping and outpainting videos

Hey Product Hunt 👋 I’m Maxim, the founder of VideoExpander. I built VideoExpander because I kept running into the same annoying video problem: you have a good clip, but it is in the wrong aspect ratio. A vertical video needs to become landscape. A tight shot needs more space. An AI-generated video looks good, but the frame is too narrow. A clip needs to fit YouTube, TikTok, Instagram, a website, an ad, or a presentation. Most tools solve this by cropping the video, adding blur borders, stretching the clip, or leaving black bars. VideoExpander takes a different approach: it uses AI video outpainting to expand the frame itself. You upload a video, choose a target format, and VideoExpander generates new visual content around the original frame. The original video stays in place, while the missing edges are created with AI. You can use it to: - Expand videos with AI - Uncrop tight-looking videos - Change video aspect ratio - Turn portrait videos into landscape - Resize videos without cropping - Avoid blur borders and black bars - Outpaint AI-generated videos that came out in the wrong format There is a free tier, so you can try it with your own clip. I’d love to hear what you would use this for, especially if you work with AI video, content repurposing, social ads, YouTube, TikTok, or product demos.
