I'm sure someone else has had this problem: you have a big Vegas project, scroll to the other end of the project, and you wait a couple minutes for the video thumbnails to update. How can I speed this process up? In Premiere I dreaded scrolling across the timeline because of the waveform updates (had the thumbnails disabled), and in Vegas it takes some time for the thumbnails. I don't want to disable the thumbnails AND the waveforms. I love seeing the waveform. Anything I can do?
