I have edited some videos from concert. I have several clips, but I needed to cut off something in the middle of that clip and make dissolve. For example I have seven m2t clips. When I make dissolve between clip1 and clip2, evertything is OK. But when I cut off something within clip1 and try to make dissolve between these two parts of clip1, dissolve doesn't work. And other transitions work badly too. For ex. slide transition makes slide from destination clip to destination clip. It is quite weird bug. Any ideas, what does it make?
