I've done a Poser video in uncompressed format and I don't know to which video format I have to convert, it's a big confusion, divx3-4-5, xvid, mpeg1-2, ????, etc and also the format for audio to be used. Which format gives the best compression and quality (video and audio)?. The frame size is 480x480.

Depends on what you want. Video for the web? Then Windows Media 9/10 provides the best quality at low bitrates. Problem is, only Windows Media player can play those files, non-Windows users are out of luck. Second best is probably xvid or divx5. High quality video: I got the best results with the MS MPEG4-V2 codec. DivX5 is also good, but needs somewhat higher bitrates to get rid of those pesky artefacts. We're talking 3 Mbps and more here.

Is a video for downloading that don't kill the bandwidth, the quality needed is not too high because it was rendered at only 10 frames per sec, but I don't want to be degraded more. Also need to know which sound codec to use.
