I recently upgraded to Vegas Pro 11. This required upgrading my editing terminal's operating system to Windows 7 (32 bit). Although the preview video monitor runs smooth on simple camera footage and simple cuts and fade transitions (HD 720p), the preview monitor seems to stall and jump (stutter, you might say) and skip lots of frames when doing more complex transitions and effects like dissolves and video over video mixing. Of course, this is just a preview quality problem, as the rendered product is fine. But it bothers me because it makes adjusting edit points a pain working in real-time with the timeline because I can't always see synced video and audio in real time in the preview monitor.
My first inclination was that this is a hardware problem (not powerful enough to handles the new Vegas 11 platform). Instead of buying a new terminal, I figured it would be cheaper to upgrade what I have. After all, it is a quad 4 processor terminal. Here is what I did: First, I upgraded my Windows 7 OS from 32 bit to 64 bit, so the new Vegas could make better use of the available RAM. I also increased the RAM from 4 gigs to 8 gigs. I also ungraded the graphics card from a NVIDIA Quadro series (32 bit) to a NVIDIA GeForce GTX 275 (64 bit).
Of course, everything now runs faster than snot on a Teflon doorknob. The Vegas program also loads faster and has much more overhead to work with, but this did NOT cure the preview stalling problem. This MUST be a software issue. QUESTION: Do any of you Vegas using guys have any suggestions on how I might tweak the Vegas Pro 11 system to improving preview playback performance?
Thank in advance.
