The Multicam feature in FCPX allows you to quickly and easily edit multiple camera angles of the same scene.
It’s especially helpful to be able to see up to 16 angles of video, at the same time.
This allows you to visually choose what angle you want, with the click of the mouse, IN REAL TIME.
So, you watch the video, click on a different angle, and now you see that new angle in the viewer (and timeline).
It’s very cool and saves a ton of time.
For those of you who do music videos, this skill give you the ability to complete more projects, even faster.
Here’s a very simple to understand tutorial on using the Multicam feature in FCPX.
