Why are my videos always blurry - use imove

[lensbaby48]

hi, my videos look great in imove or quicktime but when I upload them to youtube they are blurry. I have tried everything. I'm not an expert but I've googled and tried to get the setting right any help appreciated.

I attached to screen shots of settings. I have a Sony pj540 I shoot with. Please any advice. This is driving me nuts. Thanks!

What other compression type settings are there on that dropdown?

Yes, see screen shot. There are all these blurry patches in my youtube videos but not when I view on my mac before upload to youtube. I can msg you some video links. Any help appreciated!

I'd try the mpeg 4 one and the animation one to see if its any better
