I plan to use Vegas Video for editing.. and from the feedback so far, it sounds like I should go with the .PSD file format.

My scenes so far are simplistic made of geometric shapes and some text.  I have one scene that uses the particle emitter.  the other ones don't (so far).

The scene with particles is 10 Seconds so at 24fps it adds up to 240 Frames.  A single frame on take 56 seconds.  So it would take 3.5 to 4 hours in a single machine to render??

This is the reason I want to render on multiple machines. :)

And I can confirm what Mark is saying about a Single Frame taking 24 hours to render... I watched a show on Pixar and they were saying the same thing.

Now I wish I had the skill to produce an image as good as a single frame from one of those movies. :)
