ATEM Mini PRO with HDMI fiber - SUCCESS!

My ATEM Mini Pro arrived today and I'm wondering if the camera control signals will be sent over HDMI fiber such as this? https://amzn.to/3cqPpb1

FeizLink 4K HDMI Cable 25m Fibre Optic High Speed 18Gbps Support HDMI2.0 4K 60Hz HDR10 HDCP2.2 ARC 4:4:4 3D HEC Compatible for Apple TV HDTV Projector Roku TV Box Home Theater PS4 Nintendo Switch

Anyone tried this?

I was not tested it .. But I dont see any problem ..

Should work, but they are not bi-directional so if you're planning using the camera controls on Pocket cameras it won't work.

The connectors are marked with "SOURCE" and "DISPLAY".
That is an indication that the cable is not bi-directional.
So you will not be able to control the camera from the ATEM Mini with this cable.

Currently BMD position on this, is currently, only a direct (bi-directional) HDMI cable connection between a Pocket Camera and the ATEM Mini will allow CCU camera control. Most HDMI to SDI, fiber, conversion is not going to work for CCU, unless they support bi-directional and control codes, but will work to get a good video signal over longer distances. So if you need a long cable run, and can live with presets on the camera (no CCU control) then cable solutions like this should give you good video transmission results, and might be less expensive than buying external converters and cables.
Cheers

thanks all... I suspected as much. It's to control an overhead camera on a pool table and up to now I've used HDMI->SDI converters,
What about these ..... expensive but do you think these will work?

A lot of BS above here..

HDMI Fiber is supported. But you need the correct cables. Marc colemont already succesfully tested this with a 100M active HDMI cable. ( Procab CLV220A / PRX220A (100m Reel)


Also the TS mentioned cable supports ARC & CEC. Which are both 2 way protocols that run trough HDMI cables. And my suspicion is that BMD uses CEC ( Consumer Electronics Control ) for the CCU control.

Source and Display just indicates which direction the cable must be placed in. And does NOT say it isn't capable of bi-directional communication.

People please if you have no electronics / developer background please don't comment of things you do NOT understand..
There is so much MIS-information by users that have no clue either..

Daniel, thank you for the info....I've requested price list/uk distributor info.

Nice to know it exists, not a cheap option though.

Nice to know it exists, not a cheap option though.

For sure not a cheap option.. But i also believe you might be better off with a TVS HD and BMD (micro) Studio cameras.. But they aren't a cheap option either..

well what do you know...this is the first fiber HDMI that I've seen to support the backchannel signals. As I suspected, finding one is several times more expensive than the run-of-the-mill unidirectional versions.

but if you absolutely have to connect your BMDPCC to your $300/$600 ATEM and have CCU control from a practical distance this is just the ticket can we give this question a rest now?

Wishful thinking. Now begins the quest for the absolute cheapest Amababa version, liberally seasoned with general outrage at the price. I can hear it now, "The cables cost more than the switcher!"

These things, much like a virus, must run the course.

Good Luck

I can hear it now, "The cables cost more than the switcher!"

Yes this is the next problem.. People need something to complain about i guess.. At least there is a Solution now

Well, this is interesting and I would be grand to see some of these HDMI/Fiber bi-directional cable’s tested.
We might be in for a pleasant surprise.
Cheers

Does anyone know definitively what HDMI mechanism is being used to send the camera control signals from the ATEM back to the camera?

This information would greatly help with trying to find compatible cables. It seems like there are a few possible features in the HDMI spec that could be used for this:

• HDMI Consumer Electronics Control (CEC) since HDMI 1.0
• HDMI Ethernet Channel (HEC) since HDMI 1.4
• HDMI Audio Return Channel (ARC) since HDMI 1.4

Of these, CEC is by far the best supported since it was in the original version of the HDMI specification. Pretty much all copper HDMI cables support CEC, as do many of the HDMI active fiber optic cables. Many of the HDMI fiber products actually have a hybrid copper/fiber construction with a small number of copper wires used for bi-directional control signals (like EDID and CEC) and the fiber strands used for video transmission.

The HDMI CEC spec includes a standard set of commonly used commands for controlling TVs, set-top boxes, and other consumer device, but it is also possible for vendors to implement their own custom commands. The downside of CEC is that it has very low bandwidth by modern standards, less than 500 bits/sec. I'm not sure whether or not this bandwidth is sufficient for the camera control commands.

HDMI Ethernet Channel (HEC) and Audio Return Channel (ARC) were both introduced in HDMI 1.4 and used two pins that were previously unused in the HDMI connector to support these new features. To support the 100 Mbit/sec bi-directional bandwidth of HEC, these wires need to be run as a shielded twisted pair inside the cable. Older copper HDMI cables sometimes ran these wires straight (rather than as a twisted pair) or even left them disconnected entirely. Some of the active and fiber HDMI cables did the same as it allows for simpler cable construction.

HDMI Ethernet (HEC) never really caught on with device manufacturers, so this omission often wasn't a big deal. But more recently, the Audio Return Channel (ARC) feature which shares the same HDMI wires as HEC, has gained some adoption, especially among home theater audio receivers. Which means that cables that include this wiring and support ARC are becoming more common, and even some of the HDMI active fiber cables support this.

Cables that include the wiring needed to support HEC and ARC are often labeled HDMI with Ethernet compatible or HDMI 1.4 compliant. I believe that according to the HDMI Forum (which standardizes the HDMI specifications), it is possible to claim compatibility with a particular version of the HDMI spec, without supporting all of the features in that spec. So advertising a cable as HDMI with Ethernet compatible is actually preferred, since indicating that a cable is HDMI 1.3 or 1.4 or HDMI 2.0 compatible, doesn't actually communicate very much. Some cable manufacturers will instead explicitly list a set of supported HDMI features for this reason.

Anyway, if we knew for sure which HDMI feature the ATEM Mini camera control commands were using, that would help in finding compatible HDMI cables.

Apparetly cheaper HDMI Fiber works too.

Here is a video from Sandy Audio where he tests it out - spoiler it works.

David, great results, btw which brand cable did you test?
Cheers

Denny, I believe I found the cable on Monoprice. Waiting for confirmation on the video creator's YouTube page."Monoprice SlimRun AV HDR High Speed Cable for HDMI-Enabled Devices"

The Monoprice SlimRun AV HDR cables have the HDMI logo as a molded/embossed part of the metal connector housing, while the cables in the video appear to have a printed HDMI logo on the connector. The Monoprice cables also don't have any visible screws on the bottom of the connectors. So I don't think it's the same cable. Having said that, those Monoprice cables claim to support ARC, so if the product page is accurate, that suggests that they have the additional wiring needed for HEC and ARC and there is chance they might work.

I think the HDMI cables in the video are likely these RUIPRO HDMI fiber cables:
https://www.amazon.com/RUIPRO-4K60HZ-HD ... B07287LTRZ

The RUIPRO cables also claim to support CEC and ARC and as a result they are fairly popular with a lot of home theater users.

Thanks Dave, I have not kept up with the new HDMI cables, as I normally use SDI.
Cheers

I bought this HDMI Fiber to test it out https://amzn.to/2x8Mhl2

FeizLink 4K HDMI Cable 25m Fibre Optic High Speed 18Gbps Support HDMI2.0 4K 60Hz HDR10 HDCP2.2 ARC 4:4:4 3D HEC

At £68 - or about US$85

It's 25m and worked without any problems. Next to find a 50m and see it that works ok.

I'll be using the Mini pro as a capture and control card for my ATEM ME2. I'll feed the Pocket 4Ks into it and the HDMI out into the ME2 HDMI in. I'll need an extra screen for the control but because these cameras are usually used as overheads or high remotes it's worth the extra hassle to get control of them.

Grand, Thanks David. I have a similar issue with a multi-camera setup for live events, this looks like a good solution. Still waiting on my Mini Pro, but can get cables ordered meanwhile. Stay safe.
Cheers

I ordered 2 20m (available up to 100m and longer) HDMI 2.1 hybrid fiber/copper cables directly from a Chinese manufacturer.
The connectors are marked with "Source" and "Display" but the specs indicate "bi-directional EDID and HDCP communication", so I gave it a try.

These cables work great and allow full BMPCC6K control from the ATEM Mini.

Next to find a 50m and see it that works ok.

well the price difference between 50m and 100m was negligible. so I got this 100m cable

Much of the cost of these HDMI fiber cables seems to be in the connectors themselves (which have electrical to optical converters in them). Many of these cables seem to be made using polymer optical fibers (rather than glass) and only have a handful of fairly thin copper wires, so I'm guessing that the cabling itself is fairly inexpensive per meter. As a result, twice the cable length often isn't dramatically more expensive, since the connectors are still a big chunk of the cost.

Polymer optical fibers don't have nearly the same transmission speed or distance as glass optical fibers, but they tend to be more flexible. So I guess that ends up being a pretty good tradeoff for HDMI fiber cables since the bandwidth needed is fixed (usually 18 Gbps which is actually not that high in terms of fiber) and the cables are not that long (100m or less compared to 10 km+ for single mode glass fibers).

Adding to success of full Camera Control of the BMPCC 4K using HDMI Fiber cable.

Or this one?

I would say the second one, the cable appears it is a composite fiber/wire and should maintain CCU comms with the camera from the Mini, if it supports two way comms. You can usually tell by the ends, one for output connection and one to source (camera). I have tested a similar cable, and it works fine.

The first Amazon reference, states it is a one way cable only in the description, so definitely not that one.
Look for a cable that is optical (fiber) & Wire connectivity. The fiver part carries the video and wire part the CCU comms and other two-way info.
Cheers

Thanks. Ordered these and I'll test them this weekend. At about $1.00 per foot it's a good price....if it works.

https://www.amazon.com/AmazonBasics-Hig ... r=1-9&th=1

The LinkinPerk cables also works very well: https://medium.com/@timvervoort/fiber-hdmi-for-bmpcc4k-bmpcc6k-atem-mini-pro-iso-bde49085b00

https://www.amazon.com/AmazonBasics-Hig ... r=1-9&th=1

These 50' cables came in today and after 15 minutes of testing I appear to have full camera control from the camera control panel and was able to initiate recording.

Right at $1.00 per foot.

Does anyone know definitively what HDMI mechanism is being used to send the camera control signals from the ATEM back to the camera?

This information would greatly help with trying to find compatible cables. It seems like there are a few possible features in the HDMI spec that could be used for this:

• HDMI Consumer Electronics Control (CEC) since HDMI 1.0

<snip>

Just got off the phone with Blackmagic Design - we can use ATEM to control zoom, focus, grading, etc. on BMPCC via HDMI, assuming we have a power zoom lens and HDMI cable that supports CEC.

Hi guys,

Would this cable work:

Amazon Basics High-Speed Fiber Optic HDMI Cable (18 Gpbs - 4k/60Hz), Supports Ethernet, 3D, 4K and ARC - 200-Foot

On the 150ft it says that it has CEC but on this one I can't see it. But it seems to be the same cable?

I would just order and send back but we dont have amazonbasics on amazon in Belgium so I can order it but it will e expensive to send back.

Can anyone confirm?

Thanks guys

Without a link it's hard to see if I can see the right ones or not. However it you look up a few posts you will see where I tested a 50 foot Amazon Basics cable that works fine. They have various sizes. Link is in that above post.

I understand, but that is kind of the problem on amazon

https://www.amazon.com/gp/product/B07WZ ... 0DER&psc=1

When you change lengths the layout changes. Sometimes it says explicityly that CEC is supporteed, (like when you click 150) when you click 200 those things dissapear but the cable seems to be technically the same just longer.

The thing is, I want the cable to be as long as possible, but the 200 is way more affordable then the 300.

I think it will be okay, the descriptions at Amazon are very worse.... I bought also HDMI cables from amazon and they work perfect.
Keep in mind you have a display and a source side, if you connect them wrong it won't work.

Hello, I'm relaunching the subject a little a few years later. (But why has there been a tou for so long for so many years???

Following the advice of this discussion thread, I used different HDMI cables found on Amazon. I have been using 5 BMPCC for a long time and recently 2 Studio Camera 4K Pro (1x G1 and 1 G2). I have 8 coils of coiled cables.

I have done a lot of services with a few problems each time (especially pb of control channels for the tally and remote settings from the ATEM). But above all, problems that are becoming more and more frequent and that make me say that with time and manipulations (rolling/unrolling the reels many times), I think that these cables (probably especially the sockets that contain converters and electronics) are damaged.

There are other types of more expensive cables, sometimes with a protective cap at the end of the socket. but is this the guarantee that they try better over time, knowing that they cost 400 or 500 euros each!

Do you have experience with robust cables, CEC guaranteed, protected, and affordable in terms of price?

My opinion : HDMI connector is not maded for daily insert/pull out use ..
