1. Overview FFgui is a graphical user interface for the FFmpeg1 tool. FFgui helps you to convert video to all the format supported by FFmpeg. FFgui takes advantage of the concat demuxer2 to concatenate videos.
2. Installation There is no specific installation, just unzip the distribution in the folder you want.
2.1. FFmpeg When starting the application for the first time, you will be prompt for the FFmpeg executable.
2.2. Files The following are the main files
1 2
ffgui.exe
The application executable
ffgui.json
The configuration file contains the encoding templates and the FFmpeg home directory
ffgui.tabs.json
The tabs configuration contains the FFmpeg arguments that will be displayed in the user interface. The arguments are grouped per tab.
3. User Interface This section presents the user interface
3.1. Destination The destination tab enables to select the name of the file that will be created. Additionaly you could manage the projects, the encoding templates and start the transcoding.
3.1.1. Projects A project contains the sources, the destination and the encoding configuration. A saved project could be loaded at a later time.
3.1.2. Encoding Templates An encoding template is a set of predefined values for FFmpeg. FFgui is provided with basic encoding templates. When loading an encoding template, the predefined values are loaded in the associated tab. For example loading the “ mp4” template will define the video codec as “ h263”. The other values are not modified enabling to mix different templates like audio and video. When saving an encoding template all the defined values are saved in the configuration file ffgui.json. When clearing the encoding template all the possible values are set to their default value. When deleting the encoding template the template is removed from the configuration file ffgui.json and cannot be loaded any more.
3.2. Edit The edit tab enables to concat the sources or part of the sources. If no parts have been selected then all the sources will be concatened. If there is only one source or only one part the video will be transcoded directly, without concatenation. The videos to concatenate must have the same codecs. If you use the copy codec then make sure that the originating sources share the same codecs.
3.2.1. Sources In the source panel you could add a new source or select an existing source for the edition by clicking on it.
3.2.2. Edition In the edition panel you could define the interval of the selection and add it to the selected part. An interval is defined by the start time and the stop time. If the start time is left empty then the source will be used from the beggining. If the stop time is left empty then the source will be used until the end. When editing an existing part it is possible to update or remove it.
