How to Reduce the File Size of a QuickTime Movie

Updated April 17, 2017

QuickTime movies can use multiple codecs for compressing audio and video streams. They can also use a variety of file extensions and containers to encapsulate media files, like MOV and MP4, for example. If you need to reduce the file size of a large QuickTime file or one of its variants, you can find a selection of QuickTime-compatible conversion utilities online that can help you lower some of the attributes of your QuickTime movies and, in effect, shrink your movies.

Shrink your QuickTime movies with a free copy of MOV Video Converter (see Resources). After importing your QuickTime movie into the program, the program's "Settings" menu offers options for decreasing the size of output files. You can decrease the audio bitrate, video bitrate, frame size and frame speed to generate a smaller QuickTime file.

Download a free copy of SUPER (see Resources). SUPER gives you the ability to decrease your output file's frame rate, resolution and aspect ratio, and you can even crop unnecessary portions of your video to make the file smaller. You can also disable the audio stream if your video's audio track isn't important. Just select the "MOV" or "MPEG4" option from the drop-down menu labelled "Select the Output Container" to maintain the QuickTime format.

Download a copy of Kate's Video Converter (see Resources). Select the program's "QuickTime" option, and then click on the "Advanced" button. You can change the output file's audio and video compression codecs, lower the audio track's sampling rate and resize your movie's dimensions. Just click "Convert" after you've made your adjustments.
