Configuring a Decklink Quad 2 card with two Fill and Key outputs, the rest is video output

Goodmorning everyone,

My problem is, I installed my Decklink Quad 2 card because I need the two keys.
I have set the set quad card (1) - sdi 1 and 5 then set quad (2) - sdi 2 and 6.
The remaining 4 ports serve as individual outputs but I cannot configure them in the casparcg.config file.
Inserenso makes me look almost as if we were Fill and Kill.

Try with device number 3, 4, 7 and 8. If I remember right, that should do it.

Checkout your log file. It will identify detected devices and list them at the start.

This is my configuration file but it keeps getting me sees only fill and key

I guess…
You have paired some devices so you will find device number 1 to 6 only.

And you are getting only two fill key pair, you have duo 2 only (not quad 2).

I tried to copy what you sent me didikunz but it always continues to have fill and kay!

I enclose a photo of the configuration I’m trying to do:

Decklink%20Quad%202%20config

board configuration:

As @silid already mentioned: Check and post the logfile just after you start the server. It will list you the devices it recognized. From the screenshot you posted it‘s not clear what outputs are configured as fill & key and which are not.

I attach the newly started server log.

As you see here, you have 8 channels. If your control panel setting were correct, you would only get 6, as the two outputs set to be fill & key would appear as two channels.

It is really strange that it gives me all the individual outputs because I configured the previous scheme and the outputs fill and Kel.
I enclose all the configuration of the card
DeckLink%20Quad%20(1)
DeckLink%20Quad%20(2)
DeckLink%20Quad%20(3)
DeckLink%20Quad%20(4)
DeckLink%20Quad%20(5)
DeckLink%20Quad%20(6)
DeckLink%20Quad%20(7)
DeckLink%20Quad%20(8)

Those mappings look correct. Do you find you get a different result if you use the full config syntax like in @didikunz 's config?

Where do I find the complete configuration syntax?

In the commented out section bellow in your casparcg.config there you find lines like this

<video-mode> PAL [PAL|NTSC|576p2500|720p2398|720p2400|720p2500|720p5000|720p2997|720p5994|720p3000|720p6000|1080p2398|1080p2400|1080i5000|1080i5994|1080i6000|1080p2500|1080p2997|1080p3000|1080p5000|1080p5994|1080p6000|1556p2398|1556p2400|1556p2500|dci1080p2398|dci1080p2400|dci1080p2500|2160p2398|2160p2400|2160p2500|2160p2997|2160p3000|dci2160p2398|dci2160p2400|dci2160p2500] </video-mode>

The first value, in this case PAL is the default. Then all possible values are listed between [ and ] and separaeted by |. To make a valid line only one of the values and no brackets and separators need to stay.

I tried setting the card with the Blackmagic software every single week and starting CasparCG Server and checking the LOG file if anything changed and nothing changed.

I have the Blackmagic software does not save the configuration on the card or does CasparCG Server not read the configuration?

I was wrong, when I said, that it only should list 6. I double checked with my Decklink Duo 2 that is set as two fill and key. It reports all 4 Decklink cards. The important part is further down, after it lists the config file. On my system it says:

The problem was my configuration by CasparCG Server, I thought that the Device was the automatic numbering instead and the one of the card.
Then the corresponding SDI Key Device is to be given.
And for video outputs only change Keyr in (default)
Below, however, I am attaching my configuration to the base of the card.

The config is still weird as you do not need to give the key-device setting for a channel that has a fill & key setup at card level. Instead you need to add a line:

<keyer>external</keyer>

to the channels that are to be used with fill & key. The key-device setting is only used for cards that do not support fill & key on card level. In that case the corresponding line would read:

<keyer>external_separate_device</keyer>

and then the key-device setting is used to define the output for the key signal. So get rid of all key-device lines. set the channels, that are configured for fill & key using the external setting and set all full screen video out the default setting (that you already have) and you should be ready to go.

Yes to the channels to be used with fill & key <keyer> external </keyer>

Instead to the channels I have to use as Output <keyer> default </keyer>

I would not add spaces so NOT

<keyer> external </keyer>

but:

<keyer>external</keyer>
