I am sorry but I really don't know what to do with this. I added another video track (the one which you can see in front) to my project. But they mixed up together with the track I already had there - the second video track is visible where originally is the black surrounding around the first video. Check the picture. I have no idea what to do with it and I am quite lost. Could you please help me? I didn't do anything special and I haven't experienced this yet. How to split these two video tracks and have just black surrounding around as it was before? Thanks!
I did, but I have got three videos in there so I need three video tracks. And it always worked like that - I could have as many video tracks as I wanted and then I chose only the priority to define which video track is the main one. I am sure this wouldn't happen if there would be just one video track, but is there any way how to have more video tracks without merging of two of them where black surrounding is? As I have been always using more video tracks and this thing never happened to me before.
