Thanks for all the help and suggestions! I'll download the DivX codec and try it out. Do I need to do anything to make the codec available within Poser's animation setup? Little Dragon, as always, you are a fount of info. I am just getting started with little animations, and learning about it in general. I will have to come back to using VirtualDub or other outside software once I start making useful animations. As opposed to my little test ones }-) Again, Thanks all!
