Hi guys,

I've been using Sony Vegas 7.0 without any major problems for a while now.
I've successfully rendered a few WMV's, but now I want to render a relatively longer one (5 mins).

I've noticed that when Vegas creates WMV's, it reneders the whole video and then goes through the video a second time. I presume it is verifying the render or something.

With this longer video, it takes Vegas a good solid hour to render it, but then it just stops at 51% progress. Vegas seems unable to go through the video a second time.

I'm making this video from very large clips taken with FRAPS (clips are well over 1gig each despite being only a few seconds long) and maybe that's part of the problem? I suspect that maybe Vegas is running out of memory? I have a brand new quad-core with 2GB RAM. I tested rendering small loop regions of the video without any problems.

If I can't solve this problem - does anyone know of any software that can 'add' two WMV's together without re-rendering them (i.e. NO change/decrease in image quality), creating one WMV with a seemless transition between the two original videos??

Thank you very much for your help guys,
Adebisi.
