Re: Ninja v for samsung nx1?

In EOS HD:

This camera has nothing to do with 10bit video. It is not possible in any way.

Everything that comes out of HDMI is uncompressed, other than the color coding used, which will always be 4:4:4 or 4:2:2 with HDMI up to version 1.4. To get 4:2:0 you would need version 2.0 or higher and even then that only applies to 4K. If a camera claims to use HDMI 1.4 or lower, and actually outputs 4:2:0, it does NOT conform to the HDMI specifications.

When manufacturers refer to compressed output what they mean is that the signal is first encoded in the camera, then decoded and output through the HDMI port as 4:4:4 or 4:2:2 (for most cameras). Uncompressed output happens when the signal is sent directly to the HDMI without first being encoded then decoded. The camera itself may use a different color coding scheme to prepare the signal (such as 4:2:0) and that will alter the image colors, but technically what comes out of the HDMI port will conform to the specs of the larger color coding method even though it might look like 4:2:0.

Also, nit picking, but "clean HDMI output" means that the signal does not have the overlays that you normally see on your camera screen, such as mode, shutter speed, aperture, etc. It does not refer to anything else. Clean output allows you to record to an external recorder, which you otherwise would not be able to do with the overlays.
