Sorry for my bad English. Yes the behavior you described is how it works. But what I like to do is showing a part in track 1 and then a part in track 2 and visa verca about 10 times or so. But there is no easy way to do that. It seems to me that I have to split the video on each track at the desired transition points, make a transition and disable the following part of the track that I don't will show. That's seems lot of work. I was just looking for something like a mixer to fade between the two tracks
or a simple listbox in the transition dialog where I can choose the track which is played after the transmission. Nevermind if its not possible.
