According to Netflix’s S1H Production Guide, you must record at least 4K in the V-Log color space with a 4-to-2 bit 10-bit All-I (400 Mbps) encoding. It is crucial that Netflix must be read pixel by pixel without having to skip lines. The S1H does this by tailoring it to either a Super-35 portion of the sensor (approximately APS-C) or the entire width of the sensor. The latter makes the S1H by far the cheapest option for a full-frame camera.
The S1H is approved for anamorphic productions in the Academy for 4: 3 shots in 4K or for recording odd B-camera shots in 6K large format for a larger depth of field (3: 2, 5,888 x 3,312). You can also take a slow motion picture at a speed of 60 frames per second (4K) with a Super 35 sensor size. Other settings on the camera such as stabilization in the body and e-stabilization can be used with some restrictions (no panning with Boost I.S. mode). The S1H has a number of other features that were likely to be very helpful at the time of approval, in particular its ability to disrupt timecode.
The S1H is not a cheap camera for $ 4,000 for the body, but by far the cheapest full-size camera approved by Netflix. Mind you, the body price is only part of this equation – the lens alone on the front of the camera above costs $ 10,000.
Update 24.10.2013 14:22 EST: The post has been updated to point out that the 6K anamorphic recording can only be used for B-camera and non-main camera photography due to the lack of an I-frame codec in this format.
