UPDATE: I’ve bought a new video card, NVIDIA GeForce GTX 275, and I’ve noticed my RAM doesn’t bubble up anymore and stays low. Render times have also greatly improved.
I originally found the solution from this post here. http://www.sonycreativesoftware.com/forums/ShowMessage.asp?ForumID=4&MessageID=648182
I’m using Vegas 9.0c 32 bit on Windows 7 64-bit and have noticed this issue when using Magic Bullet Looks 1.2. If you monitor the memory in task manager you’ll see it grows and will never come back down. I have a machine with 8GB of RAM so the solution presented in the post is to change the switch in the exe to allow it to utilize more than 2GB of RAM. This has worked perfectly for me.
Here’s a run down of what you need to do:
- Get CFF Module from http://www.ntcore.com
- Open the exe file for vegas. This should be like “vegas90.exe” or “vegas80.exe”.
- Click on FILE HEADER under NT HEADER on the left side.
- On the right there is a table and on the very last cell to the right on the bottom click on “CLICK HERE”
- Check the option that says “app can handle > than 2gig address space”
- Save the file as a different file ie vegas90_new.exe.
- Run the new exe.
Now if what you’re rendering is so massive its going to grow beyond your RAM then you’re still out of luck and will have to render in pieces but at least you can get longer clips to render.
