novices like me can get help, not sarcasm, by the way your comment really helped. NOT.
... Nothing condescending about my comment (at least not intentionally), just basically telling you:
a.) You do not want to use a 4K UHD camera for FPV
b.) Why you shouldn't
You could've Googled the word "latency" if you didn't understand the meaning of my advice and/or how it applies to this scenario.
(Now THAT's intentionally condescending)
However to extend an olive branch, so to speak, I'll explain further.
FPV cameras are, by necessity, of the fastest transmission types possible. This is because at high speeds what the camera in the quad sees (which is seen by you in either your goggles or on a screen and how you pilot around obstacles) is coming at you very fast and also therefore requires very fast transmission speeds (latency) not to mention quick reflexes. Most FPV cameras are either small CCD or CMOS types and yield pretty lousy pictures because they generally have less than 700 tv lines of resolution. This is because anything more than about 600 lines of resolution causes increased latency without a proportionally appreciable increase in quality. In other words, the higher the resolution of the picture the longer it takes that picture to get to you. Also, as one increases the resolution of the transmission the time needed to transmit increases faster than the quality of the seen transmission.
The fantastic videos seen on Youtube are always taken with secondary cameras like Go-Pros, Mobius, etc or UHD cams like you mention and not
the FPV cams used for navigation. If your flying style is slow and high above the trees wanting to "film stuff" then feel free to disregard everything
I've said, as it does not apply .... however if you're into FPV racing then please certainly heed my advice.
Realizing I've completely side stepped your OP question, in admonition of your camera choice, I'll simply beg your pardon and allow Jackson to help you resolve the problem. My apologies for coming across as condescending, it was not my intention
