YouTube Quality?Hmmmm

Ok guys ive been experimenting with Youtube quality i made like 12 combinations of codecs resolutions etc etc..And still i cant get the video to be crystal clear as some others..I wanna make a cod4 fragmovie so i want the quality to be as good as possible.Any ideas?Thanks.

Did a google search and found this http://ellingtonmedia.com/blog/2007/03/07/6-tips-for-high-quality-youtube-video/ try it out.

Im rendering with Sony Vegas then directly on youtube if i convert again to get that the video will pixelate and will look far worse on youtube

just put &fmt=18 right behind the link ;)

i know that but the point is to get the best quality i can without using that and when the code get better quality :)
