The latest Panasonic GH2 patch seems to be able of some awe-inspiring stuff. The Vitaly team has been able to pump up the bitrate to a dazzling 50 MBP/S (factory bitrate is 17 MBP/S at highest setting!) and GOP3 ('Group Of Pictures.' To put it simply, the shorter the GOP, the better the quality (and less efficient) Is what they say...) Check out this footage, which is compressed for Vimeo and not even at 1920x1080! Original footage is said to be twice as good-a number of people compare this to RED 4K footage.
Not bad for a €800,- body... Aren't we having fun?
