Hello. I need to insert 4k video into the UE4. It will be an interactive map of a plane routes, and this video is a backgroung, and there will be UI items on the top of this background layer. The video works, but there is some problems with colors, exposition and brightness of the video. It looks different from the original video. I tried to turn off the posteffects, but it doen`t help. Can anyone help me?
