MP4Tools is a free, open source, cross-platform application that includes MP4Joiner and MP4Splitter to manipulate your MP4 files. To combine multiple MP4 files, using its MP4Joiner will be quick and easy as it can losslessly stitch them together without re-encoding. That said, if you want to re-encode your MP4 videos, you have the option to change the Constant Rate Factor (CRF), video preset, sample rate, and audio bitrate to customize the video to your liking.

Video Editor is an entry-level video editing utility built into the Photos app on Windows 10 to replace the discontinued Windows Movie Maker. With this video editor, you can also merge MP4 files and export 1080P videos. In addition, the tool allows you to cut, split, add text and filters, and do more.

Note, however, that Microsoft is removing the video editor from the Photos app. On the latest Windows 10 and 11, you may not find the video editor. In this case, try Clipchamp, which is a replacement for the video editor.

Pros:

• Pre-installed on Windows 10
• Provide storyboard
• Add audio, transitions, and text

• Does not support HEVC MP4
• No panorama stitching support

iMovie is the equivalent of Video Editor on Mac. This basic non-linear editing software can easily handle the most common video editing needs.

However, it is also fun to trim the unnecessary parts and keep only the important parts.

Unlike Video Editor, iMovie supports editing and exporting 4K videos. In addition to merging MP4, it also supports MOV and M4V files.

Pros:

• 4K video editing
• Has a timeline
• Various practical editing tools

Cons:

• Support MP4, MOV, and M4V only
