Not sure if anyone is using a Sony FDR-AX700 but I just purchased one and it's an awesome camera with great auto focus. My problem is when using it as a camera input into vMix at 4k 30p it has a video delay of about 5seconds, really bad. I do not have this problem when I output 1080p from the camera. I also have a Sony AX53 outputting 4k perfectly into the same BM card with no lag.
I am using Acer Predator laptop with plenty of power and a RTX70 card. An abundance of ram and cpu power as well. The cards are located in a Sonnet box connected by TB3.
Any suggestions?

Hi ! It may come from the capture card. Have a look at this video comparing Elgato 4k to Magewell Gen 2 (2 times more expensive) : Put subtitles/translation in english : around 3:00 the guy explains why there's latency with one of these 2 capture cards. Cheers.
