AlexDawson 2 Posted January 14, 2020 Is the Nauticam M24D2R200-M28A1R170 HDMI 2.0 Cable a joke or what? Whats the reason for Nauticam to create a M28 (28mm) bulkhead for a cable that measures 9m? And force users to buy new housings just to use their Ninja V recorder Housing? I really hope some 3rd party creates a HDMI 2.0 cable with regular M16 bulkhead. I docent seem impossible to me. Or that some one else creates a housing besides Nauticam. Id like too hear a good explanation here #nauticam kind regards // Alex Share this post Link to post Share on other sites
Barmaglot 205 Posted January 14, 2020 I'm not an expert, but it is my understanding that the HDMI 2.0 spec, which is needed for 4K60P support, precludes intermediate connectors on the cable, and M16 ports are too small for the standard connectors to fit through, hence the M28 requirement.

thetrickster 328 Posted January 14, 2020 Hi Alex, I feel your pain! Having the NA-GH5 (M18) and the NA-Flame housing for my Atomos Inferno - also M18. Having gone through the expensive of getting them upgraded to M24, I was very intrigued why also. a) Physically a HDMI 90' Plug won't fit in a M18 hole - tried it, even a normal flat plug won't fit b) HDMI Mini and Micro plugs aren't all that compatible with signals past 14Gbps - so they don't support 4K or 4KDCI @ 60p at 10bit. It's not just Nauticam's issue, I tried trouble shooting the issue with so many different cables, adaptors etc to see where the issue lay, only thing that work was full sized plug based cables - I didn't find one micro to full sized hdmi cable (even if marked as Premium HDMI) that would work, even using a simple micro > full adaptor. So the only why for Nauticam to provide us with support for these new 4K and higher signals was to completely move to a straight-through, full sized 'Premium HDMI' cable - even adding breaks in the cable can degrade the performance rendering a cable not compatible with 18Gbps.

Interceptor121 660 Posted January 14, 2020 I think it is actually commendable that Nauticam tackled this problem. I for one I am not a supporter of 50/60 fps video underwater and I hate the persistent slow motion videos of fish but at least if you really want to do something at that bandwidth you have some options now It is more case of asking yourself if you really need HDMI 2.0 or not 1 Share this post Link to post Share on other sites

Im sure someone will find a solution to this as more and more cameras will allow for externa RAW recording of video and the demand will increase.

ProRes RAW is not rawvideo if you have bought a camera that supports it the housing already has it There are no cameras retrofit that would support raw video and have already an M16 The only case for a retrofit is to give cameras that output 30 fps and wants 50/60 fps all new ones have an M28 installed If you are happy with 24/25/30 you can record on a card and use HDMI 1.4 for monitoring Edited January 15, 2020 by Interceptor121 Share this post Link to post Share on other sites

To be honest, I think the m24 port that Nauticam have developed is a great solution and due to the size will be future proof for inbound 8K cameras and all the stuff going forwards. Its just a shame many are stuck with M18 with cameras potentially limited by it. 2 Share this post Link to post Share on other sites

We just have to wait and see I have a solution on the way and will share it here when I know more within 2 weeks Happy weekend // Alex Share this post Link to post Share on other sites

I have the Nikon Z6 with a Sea&Sea Z6 housing. And I need to shoot Apple ProRes RAW to an external Ninja V recorder underwater, is that strange? Share this post Link to post Share on other sites
Interceptor121 660 Posted January 17, 2020 Looks like your housing is not set with any bulkhead capability either monitoring or recording as the connected is for the sync cables I really struggle to understand Nauticam fault into this Share this post Link to post Share on other sites
