AI Video Expander without cropping
AI Video Expander gives a finished shot more room while keeping your source composition in view. Keep hands, product details and movement visible. With AI Video Expander, choose a new canvas and generate space around the footage. Keep the detail you already captured and plan a version for the next placement, from a square feed post to a wide website banner.
AI Video Expander for landscape video
Use AI Video Expander to turn vertical video into landscape for YouTube, presentations and website headers. Choose a 16:9 canvas and position your source to add space on the left, right or both sides. AI Video Expander helps you explore a wider version of a travel moment, character study or product close-up while keeping the original subject as the focus.
AI Video Expander for vertical video
Bring landscape video to portrait with AI Video Expander. A wide shot can contain the setting, the people and the sense of scale that make a moment work. Extend the canvas above and below to prepare a 9:16 version for Reels, TikTok or Shorts. Keep the relationship between the subject and the surroundings as you adapt a demonstration, performance or travel clip.
AI Video Expander for backgrounds
AI Video Expander uses video outpainting to create scene area beyond the existing frame. Give a tight portrait more background or open up a close composition to show a wider setting. You can also keep the source ratio and add room around all sides with the expansion slider. Review the generated details and motion before choosing the version you want to publish.
AI Video Expander for captions
Use AI Video Expander for captions, campaign headlines and calls to action that need their own space. When a subject fills the frame, an overlay can cover the detail you want people to notice. Plan a composition with breathing room above, below or beside the action. Add the actual text, logo or subtitles in your preferred editor after downloading the expanded clip.
