The crop factor is the 3K consumption at about 1.88. The Canon Lossless compressor seems it also recording times of 30 minutes or more continuous process without the camera exploded. But what nowreally is possible: A real 3K RAW Aufnhame in 14 bits at 24fps at a data rate from the current 90 MB / s. At least not with more than a few seconds of recording time. Since the Canon but no more than approximately 100MB / s can write continuously on a fast CompactFlash card 5D Mark 3, 4K are with full 24fps still not really at hand nearby. To our knowledge, however, there is a big problem that you can not effectively lossless compress the 10 and 12-bit RAW modes. This also reduces the data rate to about 60 percent. After that could also proclaim a1ex in January, the RAW images now (with the Canon Encoder lossless compress to be able to). This is simultaneously accompanied by a reduction in the data rate. There was once reducingRAW bit depth of 14 to 10 or 12 bits in November 2016. At least in principle, for the use of the 5D Mk3 as 4K RAW camera has many pitfalls Actually, the announced features are not new, but rather a combination of already longer known hacks over which we had partly already reported. And if it is not already clear, the is now assured that it really is true.
The main developers of 4K hacks (a1ex) has deliberately elected to his special style 1 April as a release date for something to drive the buzz by an "inverse April Fool" in height. On April 1, the Magic Lantern was announced by team, that now is experimentally possible to shoot with the Canon EOS 5D Mark III in 4K RAW. Magic Lantern conjures continuous 3K / 24p 14bit RAW from Canon 5D Mk3
