How do I get better video quality with imported Avi

I have a uncompressed avi video in very good quality. Its 333 Mb. I import it to Flash 8 (embedded) using On2 VP6 in highest quality. When I make a swf its not good enoughf quality. After Importing the video it is going down from 133 Mb to 850 Kb.

I am going to make a Projector and its not going on the internet so I want a much higher quality - so that the video will look beatyful. I dont need that hard a compression. How can I get a video that is bigger in size and quality?

The video have a lot of action in it - not many frames are alike. I am using 15 frames prs. What data rate should I be using - and how much between Keyframes?
