Play video 360

i would like to run a video 360 in UE4.
I tried to put video texture on a sphere but it’s freezing.
I’m searching an option how to do it without reducing video quality (i need 4k).

Need your PC specs and video format. If you’re running on a low end machine and trying to run 4k, chances are it will freeze

i5-4690k 3.5k
Nvidia GeForce GTX 970
16 Gb RAM
win 8.1 x64

I dont think machine is a problem. But in future i will try to get 8 more gb RAM and a GTX 1070 to test.
