Format – By default allows your video to be saved as "Video & Audio" or if you decide to change the format, your video can be saved as an "Audio only" file.

Resolution – Will dictate your video’s visual quality. The resolutions 720p & 1080p are considered High Definition, while 540p isn’t. Videos with higher resolution will have a bigger save file because they are retaining more pixel information.

Quality – Dictates both the visual and audio clarity of your finished video. Ranging from low, medium, high, and what "iMovie" states as “best" which is also known as pro res. There’s also a custom option which allows you to manually adjust the megabit information of your video.
