trim AFTER playhead

Here's a good online help menu that will explain how to use the various features of iMovie:

Fading audio is easy. Put your cursor on the edge of the audio clip to reveal a little blue fade handle. Drag the handle to fade the clip.

Hi, Tom,

Put your cursor on the right hand edge of the clip and, while pressing down, drag the edge to the left. It helps to first expand your time line by moving the slider located next to the Settings button above and to the right of the time line.

Yes, you have it right. Dragging automatically trims the clip. No need for any other command. You are working in the time line of a project.

The original item remains fully intact in Photos as well as in iMovie. Trimming only eliminates a portion of a video clip from view, it does not modify the original. So, if you drag left and decide that you trimmed too much, you can drag right to restore any portion of what you trimmed. Nothing that you do in the project time line affects the original media. The project timeline only displays thumbnails for editing purposes, not the originals.

You are welcome. :)

There will be a fade handle at the other end of the clip for fade ins.
