Videos will not port over to Unreal Engine

Ok so i have this MP4 file that im trying to bring into my scene, i drag it into my contents and it loads and appears as a media player, but when i click edit to watch it, it says stopped at the top of the screen and the video plays once with a black screen and then i cant start it again, im just stuck with Stopped at the top of my screen

You’re using a very old version of UE4. In 4.10, video playback was just barely working. In particular, H.264 encoded MP4s were not supported back then and resulted in a black screen. I strongly suggest you upgrade to 4.13.1.

yes this worked, thank you, i didnt even pay attention to the updates
