MPEG4 File Joiner

MPEG4 File Joiner is a tiny and portable application that you can use to merge two MPEG4 videos into a single file, namely .m4v and .mp4 formats. It doesn't include complicated options or configuration settings, making it accessible to all types of users.

Since there is no installation involved, you can save the downloaded files to a custom location on the HDD and just double-click the .exe to launch MPEG4 File Joiner. Another possibility is to keep it stored on a removable storage unit, like a USB flash drive, in order to seamlessly run the tool on any computer with minimum effort. It doesn't change any settings to the Windows registry.

When it comes to the GUI, the program adopts a normal window with a classical appearance and neatly organized structure, where you can use the file browser to locate and select the two MPEG4 clips you want to join.

Once you specify the output directory and filename, you can start the operation with one click. Afterward, you can open the destination folder to launch the video file in your media player and check out quality results. There are no other notable options available here. For instance, the utility doesn't support batch processing, so you can convert only file video clip at a time.

Tasks were completed fast in our tests, during which MPEG4 File Joiner remained light on system resources consumption. On the other hand, it displayed an unspecified error on a couple of occasions and failed to successfully finish the conversion jobs.

We must also take into account that it hasn't received updates for a long time and it likely has compatibility issues with newer Windows editions. Nevertheless, you can test the app for yourself, since it's free.
