Yes. So how can one record something on the window

How do you use it? I used to use camtasia studio on windows and it works well. Vokoscreen appears to have a lot of features I don’t know why the ffmpeg stops running as it says in the log. Any help on this will be greatly appreciated.

Thank you

Thanks I got it now. I just have to change the directory for the ffmpeg as it is on the image.
