Hi guys,
I have big problme with video recording. When I finish recording, on phone video looks great, but when I want upload video on Youtube, video looks like this:

Dokaz - YouTube

I reset camera settings and nothing

I have Ativ S i8750 and W.P. 8.1. I was had same problem on W.P. 8.0
Video resolution is on 1080p
