The Nikon D800 is an interesting and capable camera, but it is not popular among filmmakers. This might change however, because thanks to Atomos Ninja, now the DSLR also supports higher bitrate video recording. For some of you 50Mbit/s might not be enough, but most videomakers should be pretty happy with it. Just to remind you, the Nikon D800 has a 36.3 megapixel sensor, obviously supports 1080p video recording, it also includes inputs for stereo microphones and headphones and this can be really useful in the case of quick projects. Andrew Reid of EOS HD reports, that thanks to Atomos Ninja we now have a way of getting the uncompressed 4:2:2 off this camera which is simply great and Andrew emphasizes that the uncompressed HDMI on this camera gives the full range of luma in 8bit (0-255). Here's a native file for your consideration:
"Combine this with the anti-aliasing fix and the image has the potential to be VERY nice and better than the A7R, instead approaching the 5D Mark III in raw but with a less time consuming workflow and no transcoding. Interesting!
Now the main news is that the camera has been hacked by an independent team of highly skilled developers, who are adding features to the D800 and other Nikon cameras. From the Nikon Hack Project we now have the first few patches. This is beta software (and use at your own risk). In the latest release (1.19.2 beta) 54Mbit/s modes have been added to several more cameras not just the D800; the D4, D600, D5100 and D3200 all benefitting. Prior releases took the D800 from the default 24Mbit/s 1080p to 54Mbit/s and recently even to 64Mbit/s, though the drawback is that videos can no longer be played back in-camera."
