Philip,

I got a 1tb internal hard drive just for the purpose of poser renders.

I use Vegas movie studio for editing and render to AVI or Mov files, which ever gives the highest resolution for the upload or dvd or whatever.  For youtube i only need to click once in a drop down menu and it uploads it for me automatically, (high rez):o)

The size limit is 50 megs here at renderosity, so; I just look at what ever codec that will yeild the highest resolution at that limit or below. takes 5-10 minutes.
