First, one question: Does live view work on the 5dIII while 10bit raw recording ?
Wow, great amount of detail, with youtube compression
So Canon 5dIII with magic lantern:
3K, 10bit raw (continuous) with 1:2.67 aspect ratio and crop factor of 1.8
4K, 8bit motionjpeg with 16:9 aspect ratio and crop factor of 1.7
