How to Merge, Join and Combine MP4 (MPEG4/H.264 Codec) Video Files on Windows 10/7 PC?

Merging multiple MP4 video files into one is a smashing way to make self-made movies (for sharing or uploading to YouTube, for example) or combine several episodes of a TV series. No sophisticated technology is needed to achieve this, and there are many tools can merge MP4 files. However, most free channels will wipe the smile off your face.

Taking AConverter, a free online video editor for instance, it has the following drawbacks, like many other online MP4 mergers do:

- The files to be merged must have the same format (such as MP4 file with the same codec), file size and frame rate. It is way harsh because it is almost impossible to meet this requirement.
- The size of MP4 video file is limited to 200M, which defeats HD video recording and movie merging.
- The merging process is quite slow. It is frame by frame technique that seems to be used, which make it extremely time consuming.
- Even after repeated tries, it still fails to merge MP4 video files.

Turning to MP4 video merger programs seems a better idea, but there are still shortcomings in some tools, for example, VirtualDub doesn't seem to support MP4 format, FFmpeg is difficult to process the command line, and not a few freeware programs have adware or other unpleasant plug-ins. Besides, plenty of video joiners get stuck or run slow on Windows 10 OS. How to easily merge MP4 video files on Windows (10) free and fast?
