Hmm... this may be two seperate problems, but on my work computer, I tried to render out a 90 min. video in Mainconcept MP4 and ended up with a file that I couldn't open in VLC or Quicktime.

Similarly, on my home computer, I've been trying to render-out some files to MP4 which are for archiving purposes; the idea being that if my hard drive fails, and my backup hard drive fails, I want to at least have a DVD-based backup, even if it's a crappy one at 5mbps. Anyway, for whatever reason, Vegas at home is crapping out with an error at around the 25% marker.


What I'm trying now is rendering to M2T, then seeing if I can convert that file to MP4.

Any advice? Think I need a reinstall of Vegas?

could it be a codec issue when trying to play, if you are missing codecs you can download all the codecs you need at

try media player classic, more stable than windows media,

Playing MP4 files I made before isn't a problem, only rendering. The files I'm getting have "no moov box."
