Just as an example, in the last week I have done 3 animations of 150 frames each... that's 450 frames a week.
The catch is that those were all from planetary POV, and those really fly.
I've been trying to get a forrest looking right for the last 3 days, not to mention any cam path editing. Each frame takes 8 hours to render at great quality at 720x480. That means for a couple of minutes of footage, and more than one anim, you need at least one month, with a dual core system. I can do three cores over 2 pc's, but that would still be WAY to slow.
I fear you'd have to check on a Vue forum this time, although they could give you the same time frame for their workflow...
