MP4, or MPEG-4 Part 14, is a common media format used to digital video files and streaming audio. You can add or delete basic files properties--such as "album", "artist", or "subtitles"--using your computer's operating system (specifically, Windows Explorer). Using a third-party program (such as File Property Edit), you can edit more advanced settings such as the "File Creation Date."
Find the file you want to edit.
Right-click the file and select "Properties."
Click the "Details" tab. Enter the property information that you want filled in.
Click "Apply" to apply the changes. Click "OK" to confirm the changes.
Download the File Property Edit software from the "Resources" section below. Save the file to your desktop. Double-click the "EXE" to begin the installation.
Click "Next" Click "I Accept" to accept the license agreement. Click "Next" to install the program to your default hard drive. Click "Install" to complete the installation.
Place a check next to "Run File Property Edit" and click "Finish."
Click the "Add Files" button. Select the files you want to edit.
Click the tabs ("File Attributes," "Change File Time," etc.) that correspond with the properties that you want to edit. Click the "Apply Changes" button to confirm the changes.
