Reframe horizontal video to vertical, around whoever is speaking
Quick answer
MirrorCut reframes each shot around the person speaking instead of using a fixed centre crop. Upload a horizontal recording and ask for 9:16, 1:1, 4:5 or all of them, and you get versions for Shorts, Reels, TikTok and feeds, with animated captions. Any shot can be adjusted on the timeline.
Recordings are shot wide, but Shorts, Reels and TikTok are vertical. A fixed centre crop cuts off whoever isn't in the middle of the frame, and reframing every shot by hand takes hours.
MirrorCut reframes each shot around the person speaking. One recording becomes 16:9 for YouTube, 9:16 for Shorts and Reels, and 1:1 or 4:5 for feeds, with animated captions on top and every shot adjustable on the timeline.
