Way back in the day, long before Apple turned iMovie into an app for the great unwashed masses, there was a simple way to grab a freeze frame still image from a video clip. The new iMovie, which is supposed to be easier for the masses to use to create movies, makes the single freeze frame still image capture a hideously complex multi-step process.
What to do? If you need to extract a freeze frame still image from a video clip one of the easiest, fastest ways is with the inexpensive SnapMotion app. It’s drag and drop simple. Drag a movie clip onto SnapMotion.
Move the playhead to the exact frame in the movie clip that you want to extract, and SnapMotion saves the still image to the timeline below.
Still images can be extracted from a movie clip manually, or at a specific time in the movie, or automatically every x-number of seconds (great for a strobe effect).
SnapMotion handles whatever video files formats that QuickTime Player can handle. It’s fast, easy, and no headache at all.
