Making a Reel from a horizontal video
A 16:9 video posted as a Reel shows with bars or gets cropped. Crop it to 9:16 yourself so you decide what stays in frame. AIClipMaker.org cuts the part you choose into 15 to 90 second clips and uses AI face tracking to keep the speaker in the vertical frame, exporting 720×1280 MP4. See Instagram Reels maker and YouTube Shorts aspect ratio.
