Use the Movie window
You can drag the slider at the bottom of the Movie window or use the QuickTime transport buttons to navigate to any position in a video file. The Logic Pro X playhead will then “chase” to the corresponding project position. All QuickTime transport functions interact with those of Logic Pro X.

Drag its lower-right corner.
Control-click the movie, then choose one of the following image formats from the shortcut menu.
