Magic Lantern RAW shot on 5D mkIII with Sigma 35mm 1.4f Art series lens, Sandisk CF 32GB 60mb/s which could capture 1920x960.
There are ways to shoot H264 to make it look close to RAW, but I had to be careful how to expose it properly. I exposed the last shot for the shadows (on purpose) and as you can see, color correcting it, didn't help the sky.
