MP4Tools is an open-source package which includes two separate applications for manipulating MP4 files.
MP4Splitter enables splitting a target MP4 file into multiple files, without re-encoding. The program displays a preview of the video and allows you to select the individual split points within the clip. You can then export them with a click.
MP4Joiner joins multiple MP4 files into a single video, again without re-encoding. Drag and drop your source files, reorder them if necessary and export the results when you’re ready.
Options include a setting to force the reencoding of your video, and allow you to choose your preferred quality setting. This might be handy if you’re creating clips to share with others – individual scenes from a video, for instance – and would like the files to be as small as possible.
