ok, i made a video clip from my match, but i pressed F12 to stop it ins of pausing it.
now i want to join them togheter, that works,, but,, why not in highspeedmode ???

Hello,
We don't understand why you press F12 to stop.
If you want to use [High-Speed mode], the file format of the two files must be the same.
If you added two files of the same format, and Bandicut didn't support [High-speed mode],
please send the files to bandicut@bandicam.com.
Best regards,
The Bandicut Team.
