Then produce each quarter one at a time until you get four fully functional productions.
Then you can create a new project and splice the 4 video clips together.
This doesn't really work-around the problem, it just makes it so you are more likely to get a functional clip by chance.
The odds of making a error free clip is 4 times better if the clip is 1/4 the duration. Then the final production only has 3 transitions.
As for troubleshooting the actual problem, I would try changing any codecs you've installed, if any. Also, try changing whether or not you use hardware acceleration for VIEWING the video. (in tools / options) If you've installed a codec pack, try uninstalling it. If you haven't installed a codec pack, try installing one. k-lite for windows prior to windows 7, and shark007 if windows 7.
I did render my problematic production on another computer and my first try worked without any freezes. I only ran it one time, so it may be just chance that it worked. Thats the problem with random, it takes a lot of tests to validate anything.
I actually remembered wrong which computer was having the problem. My Laptop is the computer that kept having freezing final results, not my desktop.
My laptop is windows 7 32-bit
I see that I have k-lite codec pack installed, not shark007
CPU is a core-i5
GPU is a nvs-3100 M (nvidia)
