When recording 1080p 60fps video on Pro mode , the video light and brightness keep fading out to darker and darker .
After I set the light ,iso,focus and etc., in a 8-10 minutes video,it does not keep my settings and it consistently record the video from bright to darker and darker.
It's ok firstly,bright and the light is set as arranged but after a few minutes it keeps recording to darker .
You may see the difference in the beginning and at the end of the screentshots in the same video .
The attached videos were shot by tripod and camera was not moved or the screen was not touched.
What is the solution of this problem???
