How to Fix QuickTime Gamma Shift Graying Problem- Tutorial

For years I had problems with QuickTime graying out my videos. It would make whites gray, blacks not as dark as they should be, and would dull all other colors. This is actually a gamma shift problem. After trying unsuccessfully to QuickTime compress a render of a black Audi in a dark room I finally was able to find a solution to this problem. I realized that lots of other people are probably still struggling with this too, so I made a tutorial video. It's actually really easy to fix. I probably do it in less than ten seconds now. Just click, click, click, click, and my video's ready to go. Anyway, enjoy the tutorial!
