A DVD video copy may be rather large, because DVDs are generally automatically converted into ".avi" or other big format types when they are copied to a computer. However, many programs, such as QuickTime, can compress these video files into several compatible formats. An MP4 file conversion will result in a much smaller video copy, but like any compression, your video file will lose some quality.
Click the "File" menu on the QuickTime toolbar and select "Export..." This will bring up the "Save Exported File As..." window.
Rename your file at the top of the window, if desired. Click on your export choices. Choose "Movie to MPEG-4."
Your file name should now have the extension ".mp4." Click "Save" to export and save your file.
- You can alter the compression and exporting settings in the "Save Exported File As..." window by clicking on "Options." You can choose a new frame rate or image size. Under the "Audio" tab, you can change your sample bit-rates and choose between mono and stereo sound.
- Compressing most video files will result in loss of quality.
