I'm trying to produce a simple one hour video of my sons basketball game and the computer keeps freezing between 29% and 60% complete. I have plenty of hard disk space and 2 gigs of ram. i've rebooted twice to be sure the memory was clear.  The project has 15 clips recorded in MPEG-2 totally 3 Gigs.

I am able to render it in MPEG-1 but not in MPEG-2.

Hi  dm-creative, Could be the old projects / saved and now you're loading is corrupted somewhere
How often does Sony Vegas save the project this often causes this very problem I'd suggest that you rename each save so you know which one is good and which is over written.

Are all the clips you have added to the project in the same place and same video format??
Do you have a lot of  3D effects / transitions etc? Any red clips?
Ram is not issue here but possibly the processsor speed,
If you're working on a system with limited processing power, converting to a lower-resolution format will streamline the editing process
try these guides

The video has a very simple structure, there are around 15 clips of varying lengths each of which has a simple 2 second fade (overlapping clips) and three 10 second overlays. I have a two gig processor with 2 gigs of ram, and had nothing else running.  I will view the clips you suggested.

Thank You,
David

Hi David, the fact this is your only problem>>I am able to render it in MPEG-1( but not in MPEG-2.)
I'd stick with either mpg1 or another format that Sony Vegas supports, mpeg2 is DVD and just another name for the DVD vobs, mpeg2 is improved of course over the mpeg1,, may I ask what the video scale is being used?
DVD standard is 720x480
Probably because your saving the project to hard disc Sony Vegas and or your Processor cannot process such a load.
 MPEG1 vs MPEG2
http://www.differencebetween.net/technology/difference-between-mpeg1-and-mpeg2/
You can use SUPER by eRIGHTsoft  to convert it later but do understand that when you go to burn it to DVD using your authoring software it will automatically render mpeg1 to vobs  (ie mpeg2) at 720x480
There's no reall need to export the project to hard disc in mpeg2.

Just saw this>>I have a two gig processor << not very fast if you mean 2GHz
which windows are you running?
I'm on Windows 7,
4 gig of ram and dual core processor >2x 2.250 processor 3 GHz
which video card you have can also effect video renderring, newer cards have 1 to 2 gig onboard ram taking the load off the procesor.

Your answers were helpful and resourceful. I did find in doing a second project, that it processed as the last one should have.
