How to remove black bars from a video by generating the missing picture

Updated · AI Video Expand

Cut the bars off first (most editors can crop them, or export the clip without them), then let AI outpaint the sides: it paints new picture that continues the scene, so the video fills a 16:9 screen without zooming in and losing the top and bottom. On AI Video Expand: upload the cropped clip, pick 16:9, ⁠$4.99⁠ for up to 10 seconds.

Step by step

  1. If the bars are part of the video file, crop them out first (any editor, or the Photos app's crop on a phone), so the AI only sees picture.
  2. Upload the clip on the home page: MP4 or MOV, up to 60 seconds and 95 MB, no sign-in needed. Trim a longer video to the part you need first.
  3. Pick the shape you need (16:9, 9:16, 1:1, 4:5, 5:4) and 720p or 1080p. The price goes by the clip's length and shows before you pay.
  4. Pay for just that clip: 720p: ⁠$4.99⁠ for up to 10 seconds, ⁠$9.99⁠ up to 20, ⁠$29.99⁠ for a full minute; 1080p costs twice that. One payment per clip, no subscription; or credit packs from ⁠$12.99⁠.
  5. Wait about 1 to 3 minutes. The expanded MP4 shows up in My videos, with your clip's own sound and no watermark.
  6. Download it (on iPhone, Save to Photos) and upload it where you need it.

Old 4:3 home videos

4:3 to 16:9 adds a little on each side, which AI does well: rooms, gardens and walls continue naturally. Very soft or noisy old footage can look a little cleaner at the sides than in the middle; 720p usually matches it better than 1080p.
