This is a 70 second video comparing the results of using the 5D Mark III's internal codec (ALL-I) with the video from an external recorder via ML's clean HDMI out. The external recorder is the HyperDeck Shuttle and ML is a1ex's Alpha 2 version for the 5D Mark III
As is discussed in the notes on the Vimeo, the current challenges in getting good results this configuration are: 1) the video via HDMI out is 1620x1080, requiring a zoom to get the same 16x9 image as what the 5D records; 2) The HDMI output is at 1080i, requiring deinterlacing; and 3) the output of the HDMI is 8-bit and might be 4:2:2, but could be 4:2:0.
