Questions
Can different sizes be merged?
Yes. All clips are scaled to one size (e.g. 720p); black bars may appear at the sides.
Are big videos OK?
The first run loads a ~30 MB engine. Up to about 200 MB works well on a phone; bigger files can be slow.
Does the video go to a server?
No. The video is processed with ffmpeg in this browser and never leaves the device.
