How to Compress QuickTime Files
QuickTime files, with file extension MOV, are a standard for MPEG-4 formats. They are native to Apple QuickTime Player, which is used by PC and Mac users. MOV files tend to be larger and of higher quality than other file formats, such as MP4s. MP4 compression will save you disk space on your hard drive, and will provide faster upload speed to Internet video players; however, it typically results in loss of video quality.

Tips & Warnings
In the "Save Exported File As" window, click "Options" to change your bitrates for audio and video. Higher bitrates result in better audio/video quality, but take up more space on your hard drive. You can also change your image and frame size under the "Video" tab.
