apologies what I meant to say was,
a 5 minute animation could take 5 days or more if
- 1 frame takes 5 minutes to render
- you need 25 frames a to make 1 second
then we're talking approximately 24 hours to render 1 second.........
its just that not all frames take as long and some are longer to render where as other are quicker dependant on the complexity of the scene
