Frequently Asked Questions

What does concatenate mean for videos?
Concatenating videos means appending them end-to-end into a single file. The second video plays immediately after the first, creating one continuous clip.
Can I concatenate different video formats?
Yes. You can concatenate an MP4 with an MKV, a MOV with an AVI, or any other combination. The tool normalizes everything into a compatible output.
