hmmm if I understand a 48 frames at 24 fps (film) it should be a 1.2 secs film. then if I want, lets say, a 2 mins animation I should use 2400 frames is that true? so I suppose that instead of using playback end and end time at 48.00 I should use 2400. Or, instead of 48.00 in render globals I should type 2400? which one is the one that I have to change?
