I use SuSE linux with blender and Mac os 9 for everything else. I notice that my quicktime player on the mac has trouble playing the animations I make. It stops and starts.
Just some basic recommendations would be helpful. I want to post a blender anim.
I see quicktimes on the web all the time that run very smooth.
you should use divx to compress and distobute it. not all people have access to high bandwidth. so if you want alot of people to see your work it would be best to get the file size down as far as possible. also make sure the rendered frame is small as well. post it on a web page with a thumbnail and you should be well on your way!
