Hi everyone,

We're a Brazilian church in Canada and we've been using the vMix Free Edition for the past 3 months and we loved it! We've never had any issue!
(vMix rocks!)

So, we just bought the vMix SD Edition to switch our two SD cameras but we're planning to move to HD pretty soon.

Here is the configuration:
Mobo: Asus P8Z68-M Pro (http://www.asus.com/Motherboards/P8Z68M_PRO)
CPU: Intel(R) Core(TM) i5-2500K CPU @ 3.30GHz (4 Cores)
Video: AMD Radeon HD 6700 Series
Ram: 16GB
Disk1: 1 TB 7200rpm
Disk2: 250 GB SSD

We need a capture card with 2 SDI inputs like the Blackmagic Decklink Duo but the blackmagic support team told me that the card it's not compatible with the motherboard.

"Thank you for contacting us. The Asus P8Z68-M Pro motherboards that you list appear to me micro ATX sized. Usually Micro ATX mobo's do not provide the necessary voltage to power the PCIe cards. We have not tested directly w/ those mobo's but my guess would be that they are not compatible."

Now I'm wondering if the compatibility issue is between the capture card and the motherboard or just a matter of replacing the power supply unit?

Does anybody had any experience with that motherboard and the decklink duo?

I apologize for my bad english!

Hi Charssay!

I think this is a very interesting topic. I've found quite a few non-helpful answers from BM in other forums.

I'm currently using two different PCIe firewire cards and the only "issue" I have is a small delay which is normal when using firewire cables.

1. StarTech 1394 FireWire 3 Port PCI-E Adapter Card
2. STL 2 Port 1394b & 1 Port 1394a PCI-E Adapter Card

I've asked them what if I upgrade the power supply to a more powerful unit and here is the answer:

"Unfortunately w/ the Micro ATX mother board there really isn't much we can offer. Upgrading the power supply will not fix that issue.

All the Best,

I think I'll move to another brand like Matrox or ViewCast and ask them the same question to see what they say about it. Our budget is limited and those brands are even more expensive.

My last option will be upgrading the motherboard which is still on warranty. (6 months old)


Cheers,

That's good to know Martin! Thanks.

I've found a post from you where you did some tests running the Asus P8Z77-M Pro(PCIe 3.0) with DeckLink Quad capture card.

I'm running the Asus P8Z68-M Pro and this one has PCIe 2.0 only. I think they do not support the combination of microATX with PCIe 2.0. That make sense?

I'm just trying to find a logic behind this.


Thanks again!

Hi Charssay,

I'll give decklink duo a try.

Here is the equipment I'm ordering this week:

- 2 HD cameras Panasonic HC-V720(1/2.33" High Sensitivity MOS Sensor)
- 1 BM mini converter HDMI to SDI
- 1 BM Decklink Duo
- 2 BNC to BNC 75-ohm Coax RG-6/U 100 Ft


Cheers,

Hello Alexandre just in case, and an FYI,

Matrox released drivers for vMix support today for the entire MXO2 family and the Mojito MAX card. You can get them here for vMix v11;

http://www.matrox.com/video/en/support/downloads/

Matrox driver version 7.5.1 is the correct drivers

Hi,

If you have set the input to be downscaled to "1080i HD to SD Letterbox 16:9"
then the resolution to select in vMix will likely be 720x480 and the system (frame rate) NTSC 59.94i/29.97p

Hi Martin and Egriswold,

Probably my motherboard is not compatible with the Decklink Duo as BlackMagic said.
I tried everything. The camera HDMI output is set to 1080i, I'm also following Martin's recommendation as well.
All I've got is a black screen!

- Media Express


- vMix Settings

Hi Martin,

After a lot of troubleshooting I've solved the issue.
Long story short. So, we are using the MPEG streamclip to convert some videos and we had to uninstall the QuickTime and install the QuickTime Alternative 1.81 in order to convert some .ts (Transport Stream) videos.
After read the notes at Blackmagic support page we decided to remove the Quicktime Alternative and download and install the QuickTime from Apple.

"QuickTime
Apple QuickTime needs to be installed for some applications to function with a Blackmagic capture card, e.g. Adobe After Effects. You can download the latest version of Apple QuickTime for Windows: QuickTime Download"

After install the QuickTime everything works like a charm!

I'd like to say thank you very much for your help and all the other guys that spent their time to help me on this. (Charssay, Egriswold)


Kindly,

Alexandre
