It is difficult and strange to explain but for a year I realized that by setting the X7 camera in 4096x2160 50fps both the recorded video and the live one I see on the CristalSky suddenly every now and then stop and then resume normally.
At first I thought it was a problem with the SD (I tried 8) but viewing the video frame by frame I realized that in reality the defect is that it goes back 7 frames.
I tested with two different Inspire 2, two different X7 and 8 SD. At 25 fps the defect is not there and even at other resolutions even if I set it to 50 fps, I did not try 60fps because in Europe it is not used.
Has anyone encountered the same problem?
