Frequently asked questions
Can videos of different sizes be merged?
Yes. All are fitted to the first video’s size with black bars, keeping their aspect ratio.
What if a video has no audio?
That part is added silently; the other clips stay in sync.
How long does it take?
Videos are re-encoded, so roughly the total video length; recent Chrome/Edge are fastest.
