Rather than just contribute to other threads regarding similar problems, I thought I'd log my own thread here to my specific issues. I'm getting frustrated as I've tried pretty much everything I could think of (including lots of advice I've found here and from other sources such as youtube).

I've been using Vegas for a few years now and love it. I've used it with a variety of cameras with no difficulty until recently while trying to edit some simple vacation videos. Normally my source videos consist of only one or two long files. This time, however, my source files consist of 20-30 small files (each 20-60 secs in length on average).

I *was* using Vegas 9 64bit and suddenly started getting some errors. I immediately upgraded to VMS 10. I still got the same errors (red screens, out of memory, etc.), so I upgraded my power supply and got an awesome CUDA compatible vid card ( nVidia GeForce GTS 450).....and still getting the same issues.



Here's everything in a nutshell with my current system.

Errors:
- after loading in a higher-than-normal number of source videos (maybe 10-20), I often am getting red screened in the preview window, though I still hear the audio
- sometimes when I try to render (wmv, mov, mpg1, mpg2, avi, etc.) I usually get the low on memory errors telling me to close down some programs and try again
- sometimes when I try to render, Vegas simply crashes...and sometimes it gives me the pop-up to send my error directly to Sony (which I've done a bunch of times).


Some of the many things I've tried:
- adding nearly $400 in upgrades for my computer
- going into task manager and killing off a zillion processes which aren't needed
- Running Advanced System Care Pro which has the ability to reduce Windows processes, services, etc to maximize memory
- Reducing the number of source files and trying again and again and again until everything actually works -- which leads me to believe that Vegas might have some type of source file number critical mass issue (i.e., I can edit and render with 5 source files easily, but not 20 source files....regardless of the length).
- Changing my project settings to something significantly smaller (like 640x480 rather than 1280x720 at 60fps)
- Changing my dynamic preview memory to different settings (0, 320mb, 500mb, 1024mb, etc.)
- Changing the Rendering threads setting from 4 to 1 and back again
- Adding all my source videos at once....and trying also to simply add them one at a time.
- Opening two Vegas windows and doing a copy-paste of my project to the new window and trying to render there (someone suggested this somewhere...don't remember where).
- Trying a similar project with totally different source files (to make sure it's not an error with one of my original source files)
- defragging my HD multiple times
- trying with and without Windows ReadyBoost
- trying to set my temp directory to a 16gb thumbdrive
- tried using 30fps vs 60fps in both project settings and render settings
- source videos are .mov files, but I have also tried renaming them to .mp4 files (this worked in Vegas 9 since Vegas 9 didn't seem to like .mov files)
- countless other trials and errors based on suggestions I've read or ideas I've considered


My current system:
- HP Pavilion Elite HPE-112y quad core 2.8ghz
- Windows 7 64bit
- 8gb RAM
- about 600gb free hard drive
- GeForce GTS 450 vid card with 1gb RAM ( http://www.nvidia.com/object/product-geforce-gts-450-us.html )
- DirectX 11
- 2 monitors at 1920x1200 resolution

Current Camera:
ContourHD 1080p (www.contour.com)



Speculation:
- Maybe Vegas 10 isn't recognizing 64bit and isn't using more than 4gb RAM??
- Maybe Vegas 10 has a critical mass issue with the number of source videos (if true, then it's a surprisingly low number of videos causing the problem)???


I have uploaded one sample of the source videos at http://www.illuminatus.net/vid (it's about 22mb). All the other videos I'm working with were shot with the same camera and are all relatively short in length.



Soooo....I'm lost. I think I've tried everything (at least the simple things). I've spent hundreds of bucks and countless hours to put together a stupid 10min video hah. This particular video isn't that important, but if I can't get this video to work, I won't be able to get other vids to work in the future.


BTW, as I'm relatively new to these forums, I was wondering if Sony techs answer these questions or if the answers come only from other average guys like myself....just wondering.


Thanks.... :)
