I'll tell you, unfortunately I had bad luck with the SD cards and the ones I use now meet Yuneec's specifications. It's this SD card.
SanDisk Extreme PRO microSDXC
If we also take into account that these small jumps only occur in the rotation of the gimbal, the SD card is discarded as guilty. In addition these images are recorded in false 4k and at 30fps, so the data rate is even lower.
The problem persists both in the original video format and in the conversion to Youtube. True, not many video players, regardless of computer power, are able to play 4K video at 100Mbits smoothly. I've tried those that do meet those specifications and the problem persists.
I also discard the problems of the compass because in all the last flights I have calibrated it, because of the distance between them, and the aircraft has landed on top of the landingpad. In my case I have an 80cm landingpad.
These little jumps are also seen live on the ST16S screen, not just in the final results. During Easter Week when I flew with sustained winds of 60 km/h I blamed them on the strong wind, but in the last few batteries the wind could not be considered even light.
I want to discard any possible cause that is possible, thank you all for giving ideas, because to send the camera to Germany in guarantee, when this camera has almost no distortion in the image scares me. I don't want to try my luck, in case they send me a new one
.
The option to lock the camera position and rotate the H520 I haven't tried, I didn't think of it, I will do it. Thank you
