MP4 Cutter

MP4 Cutter is a program with a pretty self-explanatory name - it allows you to split video files with the MP4 format. The tool can be easily handled, even by less experienced users.
The interface of the program is plain and simple to navigate through. Video clips can be imported via the file browser only, since the "drag and drop" method is not supported.
So, you can preview clips in a built-in media player, as well as use basic functions, such as pause and stop, adjust the volume and navigate back and forth within the stream.
But you can also change the aspect ratio, add subtitles, go frame-by-frame, as well as adjust the speed and audio delay. Once you have marked the start and end position by pressing two buttons, you can specify the output directory and filename, in order to cut out the respective piece of the video.
The video processing program requires a low-to-moderate amount of CPU and system memory, in order to finish a task briefly. It has a good response time and manages to preserve the original image and sound quality. We have not encountered any issues throughout our testing; MP4 Cutter did not freeze, crash or pop up error dialogs.
On the other hand, there is no help file available and you cannot cut out multiple selections of the same video at the same time. Plus, you cannot set MP4 Cutter to open the output directory when the task is done.
