How to Resize an MOV File
A QuickTime movie, or MOV, is the standard format for Apple's QuickTime Player. Since MOVs can be rather large files (as well as large in size), you may want to re-adjust the picture size to fit a portable media device, or to import into an editing program. Whatever your need may be, you can easily resize your MOVs in QuickTime Player with the additional Pro Component ($29.99 as of 2010) from Apple. Follow the same process as if you were converting the video to another format, since your video must be exported as another MOV in order to resize it. Please note that if you are making the video larger, this may result in a loss of video quality.
