Jumpy Preview

Any suggestions to get the preview screen less jumpy? I've followed all the suggestions from the Vegas 7 Online Help with minimal success. When I switch back and forth from Preview, Auto to Draft, Auto I get about 5 seconds of non-jumpy preview, but then it switches back to being jumpy again. I have the preview RAM set at 750.

In this instance RAM preview isn't the issue because that affects only render preview. I presume this is SD material and I would be looking at the data chain. You haven't posted your system specs but I expect your CPU is up to the job. Where is the data stored (internal or external), does that disk need defragging, what else is running, and so on. You may be better to reduce the preview RAM.

Hi,

I have had similar problems. My 'jumping' only accoured once or twice for a few sec. in 5 min. or so, and I never got to the buttom of it. I had it two different machines with diffent processors, graphicscards etc. the only common thing was that they had genuie intel motherboards with 925 chipset. I tried to mix the hardware from the two but no luck.

I have upgraded now to a dualcore for one and core 2 duo for the other, both on Asus boards, and it seems to run ok, at least on one of them so far - the core 2 dout I have not tried yet with Vegas.

I am not sure on this, but it seems to me, that Vegas might have some problems with certain kind of hardware. When I had my trouble, I got a lot of very good and competent surgestions from this great forum and the support, but nothing helped back then.

My thread back then was:

I'd definitely start by setting the preview RAM lower. Like 16 MB or less. Also, watch your page file in taskman.

As far as I can tell Vegas uses preview RAM during normal palyback. It caches frames as it goes along to make subsequent playback of the same area smoother. I have found with previous versions that if the preview ram setting is too high that windows will start dumping stuff to the page file. Alll that activity will slow down the Vegas preview.

Of course, it could be something else, too :-)

I too experienced this since yesterday when I upgraded from v6 to v7. After reducing the RAM to 0 (a setting that Wax requires), the problem completely disappeared.

For what it's worth, I too have a genuine Intel motherboard.

Excellent, excellent response from you all. It was actually the RAM setting. I brought it down to 0, and it works great. Thanks much.
