Wermus

Hey guys my name is Adam Wermus and I am still trying to learn the ropes of Animation Master(v15) 1) How do you change which camera is dominant during choreography? Say from t= 0 sec to t=3 seconds I want camera 1 to be dominant, then t=3 seconds to t=6 seconds I want camera 2 to be dominant, and then back to camera 1 for the rest of the film? how do I do that? 2) When I try to render a file it takes hours to finish rendering (20+). Is there a way to make that process go by faster or do I just have to be patient? 3) When I have more than one object in a scene for choreography mode, when I play what I have it drags, skips and is very slow making it hard for me to check if I have done what I want properly. What can I do to keep all the objects but not have it run slow? I use both a mac and pc. Thanks guys all the best, Adam Wermus
