7. Click the Stop button to stop the recording.
8. Click the Esc key on the keyboard to exit the Record screen.
9. Select the File tab and select Export > Create a Video.

10. Select Full Quality, Use Recorded Timings and Narrations. (Slides with no recorded timings will remain of the screen for the default 5 seconds.)

11. Click the Create Video button.
12. Name the file and click the Save button.
