The picture jumps (stutters) at a number of places in my most recent project - it looks as though there may be dropped frames. The original clips play fine in the trimmer, but on the time line the picture stutters. When I render a section, the rendered picture stutters in the same way. When I start a new project, and put the same section of the clip on the timeline by itself, it plays and renders just fine.

At the spot the stutters are most obvious, there is a change of audio level on the linked track. Other stutters also seem to be where volume changes, but not all of them.

Any ideas? (I downloaded most recent build of Vegas.)
