Re: Vegas 9 crashing.

I had the exact same issues and I reported this to Sony. Problem though is that they want an exact repro. My project was too large but if you have a small repro you could send it to them. I also send them a complete call stack while ago but they claim they can only look into it with repro (not so sure these issues will be fixed anytime soon as I had same issues in v8).

Here's what you can try:
- Options/Preferences/General: Disable 'Enable no-recompress long-GOP rendering' (Sony suggested that but never worked for me though)
- Options/Preferences/Video: set max # of threads to 1 and restart Vegas. This might actually help in most cases
- Use 8bit for pixel format in project properties (in case you use now 32bit)

The other thing I found out that for me the 64bit version of Vegas 9 is very solid. If you are using now 32bit consider 64bit if that's an option.

Last if everything fails I do this:
- Render as AVI / Sony YUV. This will create huge files so you need to have enough disk space. Once I get the AVI I use another renderer to render to final output (or try Vegas again)
- If above still fails after a while render in pieces and use 2nd rendering phase to put pieces together in final rendering process

Happy 4th of July.
