I am trying to trim a clip in my main timeline. If I double-click on it, it creates a new tab immediately to the right of where the words "Main Timeline" are. I edited the clip in that tab. However, when I click back on 'main timeline' the clip is unedited. Question(s): Am I missing a step where I 'save' the edits from the clip so that they load into the main timeline video? If so, how do I do that? If not, what is the purpose of creating a new tab with just that one clip in it? Also, am I using the wrong words to describe these elements of my experience? I searched in help and google and couldn't find anything like what I am experiencing.
