Video Card Question
Hello all,
I have been using Vegas for a while now however, my real time playback sucks. It is extremely choppy and not accurate and I find myself wasting hours either rendering to RAM or rendering to hard disk to see a scene. I can understand if I have many effects associated with the clip but that is not the case. I have an ATI 9700 Video card installed in my 3.2 Intel single processor machine with 1 gig RAM installed. I have no anti virus running in the background nor do I have many services running. Is my video card the problem???? If so, is there a recommended card for Vegas that you can suggest? How do I get Vegas to playback like Premier or Final cut?? I have used those systems before and they work great…. Very frustrating..HELP………Thanks..

Vegas does not make use of external video cards for rendering – this is what makes it so unique!
When playing back your video, be sure to set your Preview to a setting like “Preview”. Any higher settings with many transitions etc will slow down the playback.
The “Best” setting we use mostly for a ram rendered event to ensure quality

Normally my V5 gets a little choppy if I have transistions or FX applied to a clip or part of a clip. I usually just select the portion and selective prerender only that portion if I need to have a good preview. Doesn’t take much time at all to do that.

Is this DV or HDV. DV straight (no effects) should playback fine realtime on that quick a system (p4 3.2). HDV, specifically raw m2t, will playback kinda choppy. Are you playing back from the same harddrive as your system drive? Is DMA enabled for your drive? More system info & specifics would help.

I notice you are doing a lot of render to ram previews. This would indicate to me that you have your Dynamic RAM settings under (options/preferences/video tab) set to a high level to enable those ram renders. Personal experience has shown me if you leave this high you will get choppy playback. I now run our systems with the ram preview set to ‘0’ or ’16’MB. Since then no problems with choppy playback.
Vegas seems to play back fine and release ram at the low ram settings. Under Task Manager you will notice it gobbles up ram on playback if that Dynamic RAM setting is left high and this is where the problem seems to lie as when this is set high it won’t release ram properly.
If I have to do a ram preview I will then reset to a high setting. I know when I have forgotten to put it back down because soon as I start editing again it gets choppy playback. Give it a try. One of our systems has a high end 256MB PCIe ATI card and the other two don’t have yet they all exhibit the same problem on high dynamic ram settings, so the video card IMHO has little to do with the problem.
As someone else pointed out check that you are set to DMA on your video drives. Hopefully you have a separate drive/s for video. Other things that can compound this problem is over full video drives and bad defragmentation.
