Hello guys. I need you advice.
A little bit about my liveproduction equipment. I have 5 ptz cameras which work in 1080 p 50. This cameras connected via SDI to BMD Decklink Quad 2 (lattes BMD video setup app). This card installed in PC with i7 , GTX1660 Ti (6Gb), 32 Gb Ram and 2 SSD 1Tb.

When I added all this cameras as inputs to vMix (1080p50) I saw a lot of source drops in statistics window of vMix for four cameras. After that I decided delete all inputs and add one by one and look carefully to statistics window. Result : when I added 2 inputs - everything was good, but when I added next one (3 inputs) I saw some source drops in statistics and delay in video (in vMix), after I added 4 input I saw a lot of drops. What is wrong? What I do wrong or this is problem in BMD decklink card? Any advice welcome!

@ SerVag

Can you verify that the Quad 2 is plugged into a x8 PCIe slot?

@icestream thanks. Quad 2 is plugged into a x16 PCIE slot. (PCIEX16_3 on Motherboard TUF z390 Pro.)

@ Servag

Any other PCIe slots being used?
(essentially, i7 with z390 supports 16 lanes, GPU will use 8 and Quad 2 will use 8, otherwise, second/third become x4)

If that is the extent of your set-up then you may need to contact Blackmagic to trouble shoot the card further.

The TUF z390 Pro is a strange one, PCIEX16_3 is actually a x2 slot!
So it will need to be plugged into PCIEX16_2, with all other slots besides graphics kept empty.

it seems your system has not enough PCI lanes or also not enough power, you can do an easy test, remove your BMD Decklink 4K extreme 12G and put in your quad.....

Thank you very much! You was right. I moved Decklink Quad to second PcieX16 slot and I saw zero drops :) thanks again!
