Dynamic RAM 200MB max

Serena wrote on 5/20/2013, 2:40 AM
Just installed v12 version 563 and notice that preferences/video Dynamic RAM preview is set to max 200MB with max available 200MB; I have 16GB of RAM. In vegas 11 it tells me that 16GB (approx) is available. I have to admit that I hadn't noticed what the earlier versions of Vegas 12 said about max available, but is this correct? I've just reverted to version 486 and it also says max 200MB available.

if you hold down shift when you click preferances (or whatever option it is where you can select the ram buffer etc I haven't got it in front of me) you get an additional system tab where I think you might be able to overide what it thinks is max memory if you search for memory or ram perhaps in the search box there, ther is a lot of options.

just a thought might not be there but I say lots of stuff around that looking the other day.

As Mark E said, hold down the shift key when you select Options > Preferences.
You want the "RAM Preview Limit" item on the Internal tab of Preferences. It's most likely set to 200. The default is 32768 for 64-bit system.

What Vegas is showing, is not right. Your feed back is definitely right!

All: thanks for pointers. Just got back to the desk and in the morning I'll attempt to set Vegas straight.

Serena: very large Preview RAM is not the Holy Grail. It might make your renders very slow - and on some systems anything above 0 (null) for Preview RAM makes these systems unstable.
On my machine - also having plenty of physical RAM - everything runs best at some 22 MB and some 5 or 6 rendering threads.
In earlier Vegas versions the sweet-spot was around some 75 MB.

I like being able to make LARGE Ram Build Previews - that's my "Grail"! I haven't noticed Render time hits? TWIXTOR loves it.

Lots of interesting things under that "internal" tab; never been there before. There it shows the default 32768 for RAM Preview Limit, not the 200MB still displayed as max. When I loaded version 563 the preview ran very slowly (normally runs at full frame rate), so I went into options to turn off GPU acceleration (which I haven't found useful). It was then that I noticed the unexpected 200MB max, and wondered if I had a problem with Vegas reading available memory. Going back to version 486 fixed the replay frame rate problem, although it still shows 200MB max preview RAM (with 200MB selected for RAM preview). Of course I can't select RAM preview greater than 200MB, but that isn't necessarily a problem. Annoying, however.
