New Insta360 x4 with 8k video

Hello, I bought an insta360 x4 camera and I am not satisfied. The quality leaves much to be desired and despite 8k you cannot play it on YouTube because it freezes or does not work at all. In addition, the images clearly disconnect during rotation and you can see distortions in the film. I have already recorded a few films but I do not know if it makes any sense. Can someone comment on my films? I am sending a link to the profile: https://youtube.com/@citiesexplorer360 Regards
