An edit decision list is like a very important list that tells the people who work on making movies or videos what to do. It's like a recipe for making a yummy cake, but instead of cake ingredients, it has a list of all the different things that need to happen to make the movie or video look just right.
The people who make movies and videos use a special computer program to edit them. This computer program helps them put all the different shots from the movie or video together in the right order and makes it look really cool. But sometimes, they want to make changes to the videos, like cutting out a part they don't like or maybe adding some music or sound effects.
So, to keep things organized, they use an edit decision list. The list tells them what changes to make and where to make them. The people who work on the movie or video read the list and follow the instructions carefully so that everything turns out just the way it should.
That's basically what an edit decision list is - a very important list that tells the people who make movies and videos what to do so that everything comes out looking great!
