Unfortunatelly our Kona lhe+ only supports HD, so I can imagine simply doesn’t have any 4k firmware mode available (I didn’t found any similar mode for that particular AJA card in AJA’s control panel).
I din’t know that “additional” Unreal layer which is not distributed, and so if this layer exists the source code for that plugin won’t be available, because this AJA developer “rights thing”, it does make sense I suppose…
I’ll have to wait for another version of that plugin, maybe they have some spare time for improving this “port discover/mapping” in order to make it compatible with more AJA cards. I didn’t expect any progress on that since they will probably prefer implementing a Blackmagic plugin (again just testing their 4k/8k newer cards) but nothing to regret here again, it all make sense…
The good thing though is that AJA kona cards are so robust and well made that even without having in mind this different port configuration or even without having the 4k firmware, they actually handle both in and out operation, but with the only limitation (as far as I saw with the actual 4.20.3) that you won’t be able to make them both work at the same time (just Input video or Output video, not both at the same time, at least if you don’t use two different cards, which may probably work too).
Using the populated AJA port1 I’m able to see the input coming or if I not use that input, I can assing the MediaOutput to that port1 in order to use the main fill ouput of this AJA Kona Lhe+ card:
Digging even more, this also applies to the secondary output (Fill+Key setup). Without using the “input port” you’re perfectly able to make both outputs work making its thing with the alpha’s, which is so nice for a “not supported” card!
The editor could be “improved” to show different ports available in a better way, now for the “non supported” cards, at least with Kona Lhe+, [it shows just one port][4], instead of the default 3 ports (1 in, and 2 outs) available in that device/card.
Althought aparently this ports “not exists” you will only need to trust your AJA and [manually copy][5] and [then paste][6] this port in order to “create” new ones:
The secret is pasting in a “text field” or notepad, in order to see which sintax Ue4 editor is expecting for them:
AJA Kona Lhe+
Default Port (this is what you get when pasting)
(DeviceName="",DeviceIndex=0,PortIndex=1)
The other Ports are not defined in the editor when a Kona Lhe+ is plugged, so lets define them: (I also added the Name=“KonaLhe+” showed in Ue4 in the DeviceName of my “CustomPorts”, because why not?)
Fill Output Port=
(DeviceName="KonaLHe+",DeviceIndex=0,PortIndex=1)
Key Output Port=
(DeviceName="KonaLHe+",DeviceIndex=0,PortIndex=2)
*Input Port =
(DeviceName="KonaLHe+",DeviceIndex=0,PortIndex=1)
*Can’t be used simultaneously with output fill, because they’re using “exactly the same port”
