Multicam (lsm) is like having many cameras all watching and recording at the same time. This is really helpful when you want to make a video with lots of different angles, like for a TV show or a movie. It's like having your own personal director who can choose from lots of different shots to make the best video possible.
So, when you're filming something for a TV show or movie, you might have one camera that's focused on the actors, another that's focused on the set, and a third camera that's focused on the props. With multicam, you don't have to choose just one camera to use - you can use all three!
Multicam also helps the people who are editing the video later on. Instead of having to use multiple editing programs to combine all the different shots, they can use just one program that's specifically designed for multicam. This program lets them switch between the different angles easily and choose the best shots to use in the final video.
Overall, multicam is like having many eyes watching and recording at the same time to make the best video possible.
