I do animations all the time, I just use another program to either convert them to flash for the web, or to take down the size of the avi or quicktime for use on CD...there are a few decent ones out there but be prepared to pay for them. I just took down a Vickie animation from 8 megs to under 200k and was complimented on the fact that there was no major loss of quality due to the compression. Just play with the codec selection in the animation settings in Poser and you can get it down quite a bit. Marque
