Atomos Shogun and 4K 4:2:2 10bit - Maybe / Maybe Not

4 posts

  1. Howdy All...

     

    Anyone seen the news on the new Odyssey 7Q+ ? Not looking good for 4K 10bit at the moment...

     

    Quotes from Mitch Gross (from CD who make the Odyssey)

     

    "...The official technical spec for HDMI 1.4a or 1.4b states a maximum data threshold of 4K 4:2:2 8-bit. Both the Odyssey7Q+ and the Shogun (according to Atoms published spec) use this HDMI connectivity, so therefore we should both be limited by it.

    ----
    Video input/loop out
    HDMI 1 x HDMI (1.4b)
    SDI 1 x 4K-SDI 12G/6G or HD-SDI 3G/1.5G (SMPTE)
    Signal Uncompressed 10/8bit 4:2:2 (camera dependent)
    ----
    I think some people have been confused by this, but you can also look up the technical spec of HDMI 1.4b yourself. It can only handle 4K at 8-bit. The "Signal" spec above refers to both HDMI and SDI, or at least that's the way I read it. So in that regard, the capabilities of the Odyssey7Q+ and the Shogun match, in that we both can capture 4K 10-bit over SDI and both capture 4K 8-bit over HDMI...."

  2. Sounds like a competitor throwing around some FUD.

     

    Why would the Panasonic GH4 have 10 bit 422 HDMI monitor out, if the HDMI spec could not handle it?

  3. You can take the "maybe / maybe not" off the thread title and change it to "definitely"

     

    If you want to see 4K 4:2:2 10bit working out of a GH4 into a Shogun, watch this video.

    Going forward, please let's try a little harder not to spread BS into the forum...

  4. What an amazing piece of hardware, gee makes the Ninja2 look very basic! I'm sold!

    Lots of screen presses mind, will have to see how Nauticam have solved these..

     

    Not trying to spread BS - I just thought it was odd, that a direct competitor of Atomos would state that due to using 1.4b HDMI (which is what the Shogun uses) even their own product won't be able to support 4:2:2 10 Bit 4K/UHD via HDMI...

     

    Thanks for the update Peter!

     

    Perhaps admins, should remove this whole thread.
