When i press F8 i only see the bottom half of the original video.
Several formats were send to me, but they all have the same problem.
Anybody any clue?
Well what formats have you tried?
When I’ve seen odd video I’ve either just closed/reopened the video window, or I’ve grabbed the video window and manually resized it and then closed/reopened it.
Also - try the different options when you right-click on the video itself.
4K video file the culprit?
