Compositing problems.... or, more precisely, rendering problems

Oookay, okay, maybe I'm overdoing things - maybe my poor old computer is just too slow to handle this....

I finally finished a 2:07 min scene for The Afflicted - with the following "ingredients"...

• two colour gradients, one of these 3D manipulated
• two green-screened events
• two ProTypeTitler events
• one integrated .veg file, into which another .veg file was integrated; made of numerous things: titles, video, still images with effects, 3D manipulations, green screening
  
• one voice-over track
• one music track

... the whole thing brought together, keyframed... yada, yada, yada..... (see picture below)


To cut a long story short - I tried to render it out yesterday, and it just won't. Not only does Vegas need about 3 hours to get it done (up to a point), it always crashes shortly before the end.... which pulls the plug on my dream of being able to skip the pre-renders for every little scene ... *sigh*.

If my computer isn't able to handle 2 minutes of composited film (AMD Athlon 64FX-60 Dual Core, 2 Radeon X1950 Crossfire graphic cards, 4 Gigs of RAM), then I can scrap the dream of just putting all the .veg files together for the final render .... now.
I won't even start thinking about how long it would take if it actually would work.... two; three days?!

So, it's back to rendering in little chunks.... calm thoughts, Simone, calm thoughts.... :p

And if you wanted to ask now - no, I never do things by halves. :D
