Cut on Motion
Motion distracts the eye from noticing editing cuts. So, when cutting from one image to another, always try to do it when the subject is in motion. For example, cutting from a turning head to an opening door, is much smoother than cutting from a still head to a door about to be opened.
Change Focal Lengths
When you have two shots of the same subject, it’s easy to cut between close and wide angles. So, when shooting an interview, or a lengthy event such as a wedding.
