iMovie Exports Bring Down Quality

[Dblcut3]

So, when I screen capture my video it is completely fine, but as soon as it goes through the iMovie exporting process the quality goes down so much its almost unbearable. It appears the colors are just too light. I would like any help possible please. Thanks in advance!
