• Aspect Ratio
  You can keep the original aspect ratio of the presentation in the output movie by choosing "Keep the original aspect ratio", but if the aspect ratio of your presentation is different from the one of play window or screen, you may see black bars around the presentation while playing back.
  
  If you do not want to see the black bars, choose "Adjust the slide size to fill screen" to force your presentation to fill every pixel of the play window or screen, but it may cause your presentation looks distorted.
