Yamb

Yamb is a compact tool that allows you to use MP4Box with a graphical interface. It is designed for the users who want to work with MP4 files and do not like the command line interface.
MP4Box is a multiplexer that can import various multimedia file formats in order to create a MP4 file. It can be used by entering the commands in the Command Prompt window or by creating batch files with complex commands.
Since some Windows users are uncomfortable with this type of interaction, Yamb intends to provide you with an easy to use GUI. The graphical interface enables you to select the task that you want to perform and the source files.
In order to use the program you need to specify the location of the MP4Box executable and the temporary folder. The application can also work with other utilities such as Tagger, MKVExtract and EAC3to. You should select their location if you want to handle MKV or E-AC media files.
The application features are organized in two sections that are available in the main window. The Creation menu allows you to combine multiple tracks in order to create an MP4 or 3GP file while the Editing section deals with file splitting, joining and other conversions.
You can use the app to load multiple files, to change their order and to select the ones that you want to use in the compilation before creating the MP4 movie. The list of multimedia files displays useful information such as the playback time or the video size.
The program is also able to split a video file by specifying the size of the output or the duration of the clip. Unfortunately, you cannot preview the file in order to select the time interval that you want to extract.
Although some parts of the GUI are not completely operational, Yamb succeeds in organizing the main features of the MP4Box for quick access. This makes it a useful tool for the users who want to create MP4 movies without dealing with command line arguments.
