Ratteler, I appreciate what you say but what I'm referring to is purely the length of a scene/clip call it what you will. In most cases it's no more than a few seconds before a camera angle changes. Many people who use this program plonk a huge chunk of mocap into Poser (which incidentally doesn't have a restriction on the number of frames it can hold, just the number displayed) and wonder why the thing takes forever. Rendering just the scene and no more than you need makes good use of time and sense. The 3D equivalent of shooting loads of film and editing it afterwards doesn't make sense...
