Sometimes we shoot videos on our iPhones and catch not only the event we want, but the before and after moments too. For example, I want to make sure I catch my teenage son running the 50-yard dash at his track meets, so I start my iPhone recording sometimes several minutes before the starting gun fires. When I go back to watch the video or show it to others, I would prefer not to watch people walking back and forth and changing seats before the race starts. This is where trimming (editing) the video comes in handy.
