If you noticed that the white lines perfectly line up with the length of the clip in my timeline, that is because they are there to indicate the current start and end points of my already trimmed clip.Īnd, they are movable – you can edit directly with the white lines. In this example, my clip (highlighted by the green arrow) is shorter than in the previous screenshot, and the vertical white lines (see the red arrows in the screenshot above) in the clip above it are marking just a segment of the original, full, clip. Now, if I had already trimmed this clip before I opened the Clip Trimmer, it might look more like the screenshot below.

Note that my selected clip has gone dark, waiting for you to make edits in the clip above it, except for the upside-down blue triangle (which, if clicked, will close the Clip Trimmer ). This new clip is the same clip you clicked on in your timeline, but temporarily pulled up and out of your timeline so you can work more closely on it.
