From time to time when working on projects in Camtasia I find that the precision of the seek bar is questionable. I am not sure if this is due to a buffering problem, but typically when you move the seek bar in a preview program like Camtasia, the video preview will move to that precise position. If you slide gently left or right, one would expect the preview to change as well. This is not always the case and I am curious about the implementation of the seek bar and the video preview on windows. It is incredibly frustrating when I am trying to make certain that audio and video are lined up because they do not increment equally and are not coerced into moving in a "lockstep" fashion, or in concert with one another. Rather, sometimes the video is ahead, sometimes the audio is ahead, and in large projects that have many assets this error-prone operation is compounded, sometimes so much that I must simply start from a fresh project. Is this something specific to Windows that allows the seek bar and the video preview to be out of sync?
