I'm using Sony Vegas Movie Studio 10.0 and trying to render a 1 hour + video in avi and yet I end up with 5 separate files, all of 18 min 47 seconds long (last one is 3 min 33 sec) or 4,188,397 bytes.
Not a huge problem except that the cuts are in weird places and I'm not sure how to string them together again in DVD Architect so it plays as one continuous film (other than creating a playlist, but what to call the clips since they are all the same film?!).
It took 5 1/2 hours to render last night and I'm reluctant to start the process again without knowing the problem.
I'm eventually aiming to burn onto DVD (even though most clips are HD quality) so perhaps a different rendering format?
Another issue possibly is a lack of disk space - to get around this I rendered the file onto an external hard drive which has plenty of space.
