Channel 1 not showing alpha, but 2,3 and 4 are?

Hello all,

This is my first post. I’ll try and give all the info you need. I could use any help that you can offer. This is a brand new install of Server 2.3.3 and Client 2.2 beta (because 2.0.8 won’t show any time remaining on Rundwons). Fresh Win10 OS install.

I have a BlackMagic DeckLink Quad 2 card installed. I managed to set up four Fill and four Key channels on this card. However, Channel one plays videos on device 1 and doesn’t have a key channel. Channel 2,3 and 4 all play with their key channel’s preceding them, but channel 1 plays on SDI 1 and SDI 2 is just black.

Does anyone have any ideas for what I’ve done wrong? Here is my config file:

There is a control pannel applet, that you need to setup your Decklink card correctly, make sure, that channel 1 is also setup to show fill & key.

@didikunz That was what I needed. I read the Decklink Wiki on Caspar CG wrong. I changed it to “SDI 1” instead of “SDI 1+ SDI 2”. Once I changed it back, channel one and two started behaving as expected. THANK YOU for the push!
