Update on “temporary bad preview”… another post said there can be problems if you set your “ram render” allotment too high. So I set it to less than half my installed Ram and my problem went away. The post said (I forget who posted it) if that number is too high that Vegas will begin to write a swap file to it. Hmmm. Well, I think it solved the issue.

I got a red screen the other night. It was after I’d been adjusting the the size of the Windows page (or “swap”) file. I had accidentally set it too low.

Thank you Seth.
I discovered something about Hyper-Threading last night. As you know I have two issues, the first being, why is my CPU only functioning at 50 – 60% when doing a render or displaying preview efects? I mean, I wss expecting to see it in the 90’s as it sweats to make FX playback smooth or crunch out the render. Well, I decided to do a “Gary Kleiner” test. I took one minute of DV .avi file, added a “movie look” from Magic Bullet, added a Sony “Border”, then flipped it upside down, then rendred it to MPEG 2. Then the CPU was running in the 90’s. Finally! And that one minute of DV took 35 minutes to render, which, comparing to Gary’s test, looks pretty good for a P4 3.0 Ghz. So, I’m guessing now, at this point in time, that an H/T CPU will not work at a hundred percent with only one thread to process. But when you throw more threads at it, ie, multiple effects, then it can use all its resources. OK. But I would still like to know if others are getting smooth playback in the preview window with say, one “magic bullet” type FX running. It ssems that with my system I should but I DON’T KNOW. I don’t want to go problem solving where there may not be a problem
The other issue has to do with very bad preview playback (no effects) lasting about 20 or 30 seconds, and always when viewing the very first clip of my Vegas session,and it starts about twenty seconds into the clip. Here there obviously is a problem. The CPU suddenly drops from about 15% to about 5%, and you hear what i think is the Hardrive doing its crunching sound. I’ve tried defragg, turned off network, anti-virus, etc. So I still need to track this problem down as it’s quite frustrating. I will keep looking for hidden processes getting in the way.
Thnaks again,

Thankyou Seth.
The Link was helpful. I’ll be tweaking a little at a time. I tried disabling the Hyper Threading in the Bios but so far it makes it worse. My current theory (regarding issue #2)is that my hard drive is temporarily bogging down as Vegas tries to access files, which could then cause the CPU to slow down because it’s not receiving enough data to work at full tilt. I’ll defrag the drive and try again. I’ll post more if I figure anything out.
