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.

Step 1

Download QuickTime Player. Run the installer and agree to the terms of use. Open your video file with QuickTime.

Step 2

Click the "File" menu on the QuickTime toolbar and select "Export..." This will bring up the "Save Exported File As..." window.

Step 3

Rename your file at the top of the window, if desired. Click on your export choices. Choose "Movie to MPEG-4."

Step 4

Your file name should now have the extension ".mp4." Click "Save" to export and save your file.

Tip

  • 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.

Warning

  • Compressing most video files will result in loss of quality.
