Decklink 4k Pro

Hello,

I have a Decklink 4K Pro.
I would like to send fill and key out over the card. I do not have some kind of sdi to hdmi converter to test the outputs.

Here is my config.
What I do not understand the external keyer and key only set to false.
Does this mean card will not send out the key on second device?
Should I set it to key only to true to send really a key out.?

This config looks ok. The <key-device> and <key-only> settings are only used for the <keyer>external_separate_device</keyer> setting. They are meaningless in external keying mode. So you should be able to get a fill & key output that way.

Do you mean “Decklink 8K Pro”?
there are already few topic on that

here is my config for two F+K channels

No I think he means the old Decklink 4K Pro. I would suggest the Duo 2 over the 8K Pro if you dont need 4K, as it is more flexible in using the 4 in/outs.

Not that changes things up in the configuration file, but I was just curious since the only “4K Pro” that I found is the Intensity one, but it has HDMI connectors while he has SDI since the need for converters.

By the way, totally agree with Duo 2 over 8K Pro, the 4k or more is almost useless while the flexibility is very useful!

It is 4K Pro with SDI
