Part 1: How to Convert M4V to MP4 in HandBrake?

Note: Before we get started, you should know both M4V and MP4 are basically the same, despite a fact that M4V is sometimes copyrighted by Apple's FairPlay copy protection. Simply speaking, there's no difference between M4V and MP4 once the M4V DRM copy protection is removed. As HandBrake CANNOT handle the FairPlay-protected M4V file, the following guide is demonstrated using DRM-free M4V file.

Step 1. Run HandBrake, you'll be asked to open a single M4V video or a folder that contains multiple M4V files.

Step 2. HandBrake will scan the M4V file and display all information right there. For your first-time use, click "Presets" button on the top toolbar to unfold all presets on the right side. Select any option based on your actual need.

Step 3. Select "MP4" container in the drop-down list of "Format" under "Summary" tab. For experienced users, you can customize settings under other tabs for further editing. Make good use of "Add to Queue" feature for HandBrake batch conversion.

Step 4. Click "Browse" button to specify a destination to save your converted MP4 video.

Step 5. Press "Start Encode" button to convert M4V to MP4 in HandBrake.

Part 2: Force HandBrake to Save as MP4 Not M4V

Sometimes you may find that the converted file is saved in .m4v extension even though you have modified output format as MP4 format, so what gives? Based on HandBrake Official Documentation, "For MP4 files, HandBrake will automatically use the extension M4V when you pass through audio (AC3), use SRT subtitles or have chapter markers enabled." Because QuickTime or any QT based application, iPod or iTunes will not be able to play a MP4 file with these features enabled, unless it's saved in M4V extension. But if you insist on MP4 extension, you're able to force HandBrake to change M4V to MP4 through two methods below, either is workable.

Method 1 - Change M4V to MP4 When Assigning the Destination

Before clicking on "Start Encode" button to process the video file, you're allowed to change ".m4v" extension to ".mp4" in the "File name" box when you alter the output folder, as shown in the following screenshot. The trouble is you have to manually change it every time.

Method 2 - Choose "Always Use MP4" in Preferences

Definitely, you can also settle the matter once and for all. Launch HandBrake, click on "Tools" button on the top menu bar and open "Preferences". Navigate to "Output Files" option on the left side, then select "Always Use MP4" in the drop-down list of "MP4 File Extension". Lastly, restart HandBrake to take effect.
