Part 2. How to Convert M4A to MP4 Video on iTunes

Although using a specific converter to change M4A files to MP4 formats is easier, iTunes can help with this task as well, though with some restrictions.

Step 3You can drag the M4A file you wish to add to your iTunes library or go to File > Add File to Library and find the file you wish to add.

Step 4Select the M4A file in your library. Click on File > Convert and choose Create MP3 Version. Now iTunes will make a copy of this file in the MP3 format.

Step 5After copying the MP3 file, locate it under All Files by right-clicking it and show it in Finder. Rename the file and change .mp3 to .mp4. When you are asked to confirm the change, click Yes.
