A concept I didn't know how to describe adequately for search engines:
"Final Cut Pro: Create a single frame to put in your Timeline
You similarly can create a "freeze frame" for the Timeline that will display as a still image that lasts for several seconds in your movie.
To do this, select a clip in the Browser or the Timeline to display it in the Viewer, and then move the playhead to the single frame you want for your movie.
In the menu at the top, select:
Modify...Make Freeze Frame
Click on the frame in the Viewer and drag it to the point you want it to appear in the Timeline.
You then can grab the edge of the single-frame image to shorten or lengthen the duration of the image in your movie."
Mac: it just works:

And the wonderful autosave doesn't automatically open the recovered file when the application is restarted. For the average user, this makes autosave undiscoverable.
