words such as “like” or “dude”. you may be excited or nervous about being on camera but watch your pacing, don’t speak to fast or too slowly. take a drink of water first, trying to talk with dry mouth turns into a garbled mess.
grab a friend and practice with them or set up a camera and pretend you’re doing the interview right now. don’t be afraid to look directly into the camera, it is like looking someone in the eye when you speak to them. get rid of the nervous energy before you get in front of the camera so go for a walk, do some stretching exercises or whatever
