I want to evaluate motion, camera moves, etc., preferably in OGL -- I can't seem to find this in the Manual, and it seems no one has covered it on YouTube (at least I haven't found it if it's there) ... There must be a way to make a quick PREVIEW of the animation that can be viewed in real time, without waiting for the entire render ... If so, HOW?
It'll use your regular render settings for frame ranges/formats. Personally, I like to render a sequence of pngs/jpgs into a temp directory, and then load the sequence in the Sequence editor. But some people prefer a separate movie player application.
