I just installed 20.02.17 and I can not resize timeline and playlist windows … playlist goes from mid to bigger but not to smaller than half full screen space :-(((
Timeline I can not make bigger than it is … I have many layer and this difficult my job
Yes, there needs to be something on source in order for it to be available for export. If video is added to timeline then the From option will then show both Source and Timeline as you would expect.
Further to this (albeit this explanation serves no purpose ), If the video is then removed from the Timeline (so no video is on source or timeline - effectively no video has been added to Shotcut) the From option still shows Source and Timeline. If you then attempt to export, Shotcut will actually generate an exported video which takes 1 second to complete and the exported video is 00:00:00 seconds long.
