Play Video in Main Menu

Hello, I can’t make menu , bacause video don’t playing. It’s work only when Media Player open. I did everything as in this video :

It looks like you don’t have the open source connected to the execution. Connect the Add to viewport to Open source, then that to the Play.

I am also having this issue, done everything he said yet it’s just displaying a static image of the video. Same blueprints as in the video. Tried what the comment above said. seems to work with a different video I rendered in after effects. same format though? Any help is appreciated!
