Ok so I've got an 720p HD video that's about 10 minutes long that I want to export. The problem is I want to keep it under 250MB but still look good. I just don't get how I can do this. I want a WMV version and a QuickTime version. Right now I'm trying to do WMV.

Look at this video as a reference:


It's 720p, it looks great and it's only 188MB in size. HOW?

My video comes out looking terrible and the filesize is way bigger. I've tried every export setting I can and I just can't get it looking right. Any suggestions?
