I am working on a long, 10-hour project with a lot of B-roll. Initially there was only 512 MB of RAM on the system, which was understandably sluggish. But it is now upgraded to a total of 2.5 gigs of RAM and Vegas is still previewing sluggishly with even minimal effects (dissolves, pan/crops) that it should be able to handle better. The RAM preview preference setting is at 1024MB, which it says is the max available. I actually get smoother playback on my old laptop with only 256 MB.

Worse, I am now getting an error message when trying to load a .veg file that I am using solely as a B-roll bin (as a way to get around using Media Manager but still have "tags" through my subclip names, which unfortunately don't carry over from one Vegas project to another).

The error message reads "An error occured while loading the project file...The system is low on memory. You may be able to reduce memory usage by closing other applications." But nothing else is running besides one other instance of Vegas containing the current hour of the project that I'm working on. The "B-roll" veg file references over a terabyte of footage spread over 3 drives; could it have maxed out as I keep adding more footage to the Project Media? It had been working well until now.

The drives all seem to be working fine and I've had no problem actually editing with all that B-roll in the main project (other than the low-res playback when there are effects). Is there something I need to do to get Vegas to recognize that it has 2.5 GB of RAM to work with? It's a P4, 2.6 GHz.

Thanks for any suggestions,

Julie
