Visible Movies folder (how to make it invisible?)

Hi, how you doing?

So, I have set some cutscenes in my game, these movies are in .mp4 format and they play with unreal media player.

When I packaged my game via command line, I saw that folder ‘‘Movies’’ contains all my mp4 files, so any player that buys my game will be able to see the endings right away?

Should this mp4 movies transform itself in a PAK file?

What should I do???
