Questions
Can I merge videos of different sizes?
Yes. Every clip is fitted into the first clip’s frame with black bars where needed, so put the clip with the size you want first.
Is there a length limit?
Only your device’s memory. Long 4K clips may be too large for the browser; 1080p phone clips work well.
Is anything uploaded?
No. FFmpeg joins the clips on your device.
