Premiere2.0 output video quality is low, how do

I Premiere2.0 output of the video quality is very low (mostly photos, video), I use Premiere's built-in media encoder settings, the election is the MPEG format, the output of video quality is still very poor, I would like to Output of the highest quality video (although not the best, only better), please advise!

you look at the beginning of the establishment of project files when the option may not choose the video quality and a number of factors
1, the pixel photos
2, set the output
3, generated format for the first
I think there is no way to change the second time in the output of high-quality low-speed settings relevant documents generated great On the other hand low-quality high-speed file is relatively small for the third high-quality video to be generally generate Avi Mpeg2 Rm (low compression), and other formats
