The problem of cinegamma
 

The problem of cinegamma is that when something is about to overexpose it does it very fast so the image is useless.

Has anyone notish this? check this www.macgregorcorp.com/chica.avi

That's by design, not a problem. See this link for more details:

Actually, the problem is really easy to solve in post. Simply apply a curves filter to the footage, and make a nice knee from the highlights into the midrange-it helps a lot and basically solves the hard clips in the highlights problem. If you can't do any color correction in post though, and you're having problems with the highlights, then it's probably better to just shoot with one of the other three gamma modes. Hope this helps.
