How to package so media load immediately?

Hello,

I have a series of 360º videos in my UE4 project. I just packaged it on windows for the first time and upon playing my build, I saw that the videos take a very long time (~10 sec, sometimes more?) to load.

What settings can I input to tell Unreal to ‘pre-load’ these movies?

In my blueprint, after certain triggers, I used the blueprint node “open source latent” (which loads the media player/movie) which I saw advised by a user on youtube. . .

Is there something I should do with Asynchronous Loading? Or the Asset Manager??

My build uses a .pak file, but I don’t know what that entails.

Thank you for your help!
