I'm Trying to create a gaming trailer using camtasia 8.0.4. The Problem is , when i try to combine all the clips gathered from various videos the produced video shows some kind of tearing/pixelation at the time of switching from one clip to another. Also while playing theclips on the timeline the video stopps playing for a short while. is there a solution for this? How to do so? Please help !i have attached images of the pixelations. Please take a look.
