Exported Video freezes while audio is ok


I tried shotcut and it seemed to work quite well. Use it to convert video for youtube. Nothing complex, just removing a few seconds at the beginning and sometimes adding two video together (one after the other). Without realizing it first, sometimes the resulting video freezes, while the audio is still working.

You can seeh it here: https://www.youtube.com/watch?v=zROPaebxORc
Go to about 13:20 into the video and the problem should be clear.

First I thougt it might be because of the experimental GPU processing. But even with that switched off the problem still occurs.

Using Win10. Does anyone have an idea?

Best regards,

Try to open MTL as a clip (or something like that) and try to export again.
