how do I prevent this video corruption?

lol… heaven and stress free ! Love it!

Thanks. I really liked the GPU for the significantly faster render times. Again, a feature I may have to forego.

Which card do you have? I purchased an NVIDIA specifically to reduce render / preview issues. no such luck.

“Bug” is a touchy subject for me because many, many people use Vegas 12 with no problems at all. I just finished encoding six MPEG files for DVD’s and my biggest problem was keepng from mixing up the discs as I moved to the labeling workstation. Those white discs all look alike….

If you have to restart Vegas to get a clean encode, then something in your PC is corrupting the data in memory that Vegas is using. But it’s not Vegas. You can run resmon.exe to view the memory usage of all process that your PC is running. The one that increases the commit amount over time is your culprit.

I have Vegas on two workstations – on one the GPU never worked right, and on the other there’s no problem at all. But with a sufficiently fast processor, the GPU doesn’t really add anything anyway.

I dont use a GPU Card anymore. as i mentioned earlier, i go strictly
on Processing power alone.

The card you use is not GPU enabled? I thought most of them were nowadays. or… is it an older card?

[Stephen Mann] “If you have to restart Vegas to get a clean encode, then something in your PC is corrupting the data in memory that Vegas is using. But it’s not Vegas.”

I’ll disagree with that. Bugs easily, and most commonly, exist where 99 of 100 or 999 of 1000 circumstances work but that one very specific situation fails. This is also why you have to be very careful fixing bugs.

Only processes running in kernel address space can possibly corrupt some other process memory without it’s consent.

Vegas is a very threaded, lookahead system and this makes reproducing an exact situation difficult if the issue is memory organization and corruption related.

[Gilles Gagnon]

In respect to memory over-writing, I think Norman has a good point. Only kernel mode processes can stampede over other processes’ ram and… if this were the case, from badly written kernel modes application(s), the entire system would tend to crash and misbehave randomly, not just in Vegas.
very interesting topic.
my 2 cents.

You are correct Norman, it is a deeply entrenched issue
with Vegas and one thats hard to reproduce, which makes
some users experience it and others dont.
It is a Sony Vegas issue, but Vegas is still the best…lol

Is there a method of turning off GPU globally for renders or must it be done for each render template?

UPDATE:

For what it’s worth, I’ve observed that this “corruption” appears much more frequently when I have 2 or more Vegas instances simultaneously opened or… when I’ve opened (and closed) more than one simultaneous session in an edit session.

I do this regularly. It’s Vegas’ not-so-charming method of providing us editors with a variety of edit timelines, found in other NLEs. The actual name for this missing feature escapes me.
