The app matches frames by finding where they overlap. A smooth, unhurried scroll gives it plenty to work with. Very fast flicks can jump past a whole screen of content, leaving nothing to match on.
That means two frames had no measurable overlap — usually a fast scroll or a jump. Rather than silently inventing content or dropping it, the app joins them and tells you exactly where the uncertainty is. Re-record that stretch more slowly and it will stitch cleanly.
Every frame is compared against the last one to find the true overlap, which is what keeps the seams invisible. Longer recordings mean more comparisons. You can leave the app while it works — if you allow notifications, it will tell you when the result is ready.
Frames are uploaded to our server only to be stitched, and are deleted as soon as the job finishes. Nothing is kept and no account is required. See the privacy policy for the full detail.
