hoi Matthijs,

about this update. be aware you download is from after march 3 because i had an issue using it with tb3, they fixed it but no new version number.

aparently the memory issue is fixed. have to test it with my bm duo 2 and akitio but no time yet.

these updates and issues consume way too much time, its a risk and it is annoying. good we have this forum to inform each other, but also post issues on the bm fora and send your complaints ti bm emea.

if bm wants to issue new products and drivers they better be sure the work or fix it with highest priority.

greetings,
stefan

Hi Guys, newbie on this forum. Thought I could chime in on this topic.

I'm on the brink of purchasing vMix and using the Blackmagic Decklink Quad 2 with it. I happen to own other blackmagic gear, and from the inception, I got quite confused and almost returned them.

But here's what I learned. ALL BLACKMAGIC DECKLINK PRODUCTS ARE NOT PLUG-n-PLAY. You have to configure them through their 'Desktop Video Software' utility in order to use them successfully.
The Quad 2 in question is quite tricky but very good when configured properly. Half of it's connectors share bandwidth with the other half; but it is an option that must be selected in the utility. For an example, if each of the sdi connectors 1 to 4 are mapped to multiple sdi connector outputs(on the same card), their shared bandwith connectors of 5 - 8 will AUTOMATICALLY be set to "NONE", because the shared connectors are being used. This will result in no video on those outputs.

However, there is another option in the software that allows you to map individual connectors as individual outputs, so as to achieve 8 individual signals (Wow, this is the most I have used "individual" in a sentence-phew). It is highly unusual to have ordered 4 faulty cards successfully, as the OP stated - no pun intended.

It's all in the manual -bro. Let's give it a shot before knocking down this wonderful piece of hardware.

does anybody know or have experience with turning inputs on and off and on again on a bmd duo2.

I see both 1 and 2 inpuot but the 3 and 4 are grayed out. with the control software i am able to set output configuration, but I don t know how I turn the out put off and open the input.

maybe it is something vmix must do but when i input nr 3 vmix returns an error, there is no active input.

in the bmd capture software the inputs 3 and 4 are grayed out.

the sdi inputs work when i input them on 1 or 2.

this is driving me crazy, because in the office it works and when i arrive at the recording site, bmd starts to reinstall the card etc etc and only 1 and 2 the main inputs are visibele.

using bmd decklink duo 2 in thunderolt3 with akitio.

Richard ? any thoughts.?

my aim is to have it work and as reliable as a hardware mixer but this is not what i want, unpredictable.

ok so I guess it is defenately important to have the akitio connected thruogh tb3 before start up of the laptop or anything.

now its fine again. I guess I have a little bit different routine on site than in the office and hot plugged the akitio. it works, but not on full capacity.

card is working fine... just uploaded my recordings of yesterday on www.watertv.nl and the recordings on both systems are about 45 gb each. transferring the files on a portable hss usb3 i noticed the same thing: transfer is about 10mb/s hot plugged but 100mb/s when the laptop (msi reference) is started up with the usb3 drive connected.

so hot plugging and performance are two things un equal performance wise....

I'm also interested about this firmware update problem. I would like to buy Decklin Quad 2 if this problem is solved now. I didn't find any info about this.

I had the same problem after upgrading to the latest firmware.

I found that the only thing I had to do to enable them again was to go into Blackmagic Desktop Video Setup. Go into SDI Decklink Quad (5-8) and change connector mapping

After that all 8 ports was working for me again

I'm RMAing a Quad 2 that bricked itself when it spontaneously wanted to do a "software upgrade" last week. After a long call to BMD where they claimed to have no record of this type of problem with the Quad 2, they agreed to send me another overnight so I could make a deadline. I pay the $40 overnight charge and return the bad card at my expense.

NOTE: When using the BMD Video Utility to access this Quad 2, the utility said no device was found. So, there was no way to simply reconfigure. Downgrading to BMD version from 10.8.5 to 10.8.4 and then to 10.7, I could not revive the card.

Now I see that, as of two days ago (4/13/17), BMD released 10.8.6 which purports to "Fix intermittent device detection issue." Maybe that's what the problem was. So, before I send this RMA Quad 2 back, I'll test it with 10.8.6 and post my findings. Hopefully this will fix the issue with the Quad 2 and restore my faith.

BTW, when I installed my new Quad 2 and it wanted to do a "software upgrade" I simply said, "No," and then disabled BMD Updater in Task Manager so it would not ask again.

I would advice in case 2, to first install 10.8.6 and see if the card comes back to full functionality, as mine did.
If not, you can always RMA it.

That can indeed be the case, I did deny that every time it asked me to because it was displaying the wrong product anyway, so that could not be good.
But when denying the auto-update to happen, it still broke 4 channels on the card and made it not appear in the BMD utility. That behaviour can be fixed without shipping it back to BMD by installing 10.8.6.
If users have systems that still use older desktop video drivers, I would remove the Decklink Quad 2 from the system, uninstall Desktop Video, Install 10.8.6, reboot the machine, shut it down again and put the card back in.
That way the chances of anything bad happening are the smallest.
