I had lunch with a friend this afternoon who mentioned a little piece of software that processes the H.264 footage from the 5D much better than the Canon FCP plugin. I’ve not had time to test it out but the example images on the site look great. They are doing a public beta first then the full version which will apparently have batch rendering and some other pro features but it’s free right now so download it while it’s hot…
Find it right here: 5D to RGB
