Hiya everyone, I am a newbie and suppose that I have to learn like everyone else but I am getting annoyed with my VP ver 2.41. I add a clip and then add another without any transitions. When it come to replay the clips stutter and even seem to stop at the joint. it is cery frustrating as it makes the job very hard. I want the cuts to be clean with continual flow but these micro stops are really frustrating. Is it something very minimal that I am missing. Can anyone help. Regards Rattlesnake
