I have conducted a couple more tests and maybe someone can help me interpret the results.
I tested the same FS7, extension unit, and 6g SDI cable on a Ultrastudio 4k with a different machine and it also only recognized the 4k as 1080p. I used a different FS7 with the same settings, same results, so I can rule out the FS7 being an issue.
I tested a C300 MkII with it’s 4K out, same results with the ultrastudio only recognizing the signal as 1080p, but an odyssey recognizing the same signal as 4k.
The only successful test I got was to output the 4K signal on the FS7 though the HDMI port, in which I had to restart the Ultrastudio for it even to recognize. This is keeping in mind that 4K only sends out of the extension unit on the FS7 as 4k Raw, the SDI port on cam only sends 1080.
So I guess my question is, why can’t the SDI on the Ultrastudio 4k or the Decklink 4k SDI recognize a 4K signal, either as UHD or 4K DCI? Also, I’ve been keeping the FPS at 23.97 to keep data size down.
Thoughts?
Is it due to it being raw? 4:4:4 perhaps?
