I'm making a mod and I want to experiment with video cutscenes for story and showing an area... I don't think I'll be good at real-time cutscenes lol.

Is there a way I can make a new-game play a video file in-game each time it's created? And if so, can I make it so the game can play video before loading a new chapter?
Like, you finish one chapter, move to the next, but before the next chapter map loads, it plays a video, and then loads the map?

Thanks!
