Adding B-roll

B-Roll is anything video footage used that is not the main content of your video.

I.E. If you have a video interview of someone talking any clip that you put on top of them talking is considered B-Roll while the shot of them talking is called A-Roll.

Don't forget to use those Hot Key's "i" and "o" to set your in and out points for each clip. It makes your editing time go way down!
