Whilst making videos do you look directly into the lens of the camera or do you watch yourself from the screen at the side? I tend to look all over the place, i'm naturally an over excited person.
I try to keep looking at the lens for the same reasons.I try to look into the camera. My view is it's like eye contact in the real world - good eye contact makes someone feel more able to connect to you.
Though, I may give this a try.BUT, I learned a tip that can be applied to both videomaking and life in general: when getting shot for a photo or video, try to look a few inches above the lens of the camera. For my school photos, I look more natural when I used this trick, rather than an idiot looking intimidatingly straight into the souls of the picture viewer
