sometime ago, i've notice a question about the unability to geberate avi file with poser. since i've got 2 computers, i've notice that the first one generate error message "error on creating avi" or "bad class avi file".. nor the second... it depend of which video codec is installed by default (i've got a graphic aquisition card on the first one and the installation had made a new not really compatable video codec). so if you've got this error message type, then change the video compressor codec for VIDEO 1, the most compatable). MY QUESTION IS AS FOLLOWING : HOW CHANGE THE DEFAULT VIDEO CODEC WITHIN WINDOWS OPTIONS ? (i've seek in ini files & registery, but there's hundred places where the keywords codec or video are).... A wisdom reply would be welcomed...Thanks by advance !!!!! by the way i've the eyes poped out head and head poped up corpse with my created figures (not in 3ds max 2.5) but when importing in poser 3 (such i've noticed the question in other messages).. so i import independently and move/replace parts with prop in poser)... have a good day

I don't think there is a default codec in Windows. Codecs exist in your system to be called up by programs that need them. A particular program might default to a certain codec, but you can usually change that quite easily. For example, in Poser when you choose "Make Movie" and specify the filename and path, you then get a dialog box with a popup allowing you to pick the compressor (codec). However, you might want to consider whether you actually even want to save as an AVI from Poser. When you use a codec, you are compressing your data and generally losing quality. If you then take your output into another program, such as a video editing or compositing app, you are already starting with quality loss. Then, if you render from there, you lose another generation. I generally "Make Movie" in Poser to Photoshop (.PSD) single frames, which doesn't cost any quality. If I'm compositing, I bring those frames into the compositing program -- most can import numbered frames and treat them as if they were a single video clip. If I'm going from there to a video editor, I'll render my compositing work as single frames, bring them into the video editor, do what I need to do, and then output a final AVI. It's a lot easier than it sounds, and the quality is maintained throughout the project.
