I have recently noticed that on a 3d workflow, transitions that have a cross fade set to overlap, when rendered, will freeze frame the clip while it dissolves onto the second clip(almost like a cross dissolve) but it does not do that to all the clips on the project, it is totally random. This behavior does not appear when playing in the timeline, only after rendering. I have the latest drivers for my video card and I have rendered with and without acceleration, all to no avail. Has anyone else encountered this issue? Many thanks for any help that can be provided regarding this issue
