Just like when creating an event with a single movie, you’ll go through all the steps. The main difference is in the ability add the multiple films instead of only one.
There are, however, a few layout implications. We’ll write about them later.
In the Event editor >Manage Film > Event Type, choose Multi Film Event in the drop-down menu.
Then, choose the films in the order you want them to be presented.

Basically, that’s it.
In the website (front-end), users will see a playlist and the films will play one after the other. running a pre-roll is as usual. The pre-roll will run only before the the first film.
