A simple cut in the timeline is when you remove a previously existing video from the timeline. When you cut a clip the other videos in the timeline stay where they were. A ripple edit is when you remove a clip from the timeline and then close the gap left by that video in the timeline by moving the other videos together. You do this by right clicking the video you want removed the clicking ripple delete. Lifting and extracting are two ways to remove portions of clips at one time. To do this you set the in and out points (set them as the portion you want deleted) then you click on the lift button if you want to leave a gap, or the extract button if you dont want the gap. Lifting is like a cut while extracting is like a ripple delete in terms of what happens to the other clips in the timeline. This is an exampple of an extracting edit. I decided to extract the portion of the two videos where I did because this showed the most action with the best part of the other girls smile.
