AVI-Mux GUI is a free and open-source graphical user interface (GUI) application for creating and editing AVI files. It is designed to be a powerful tool for creating and editing AVI files, and it includes a variety of features for manipulating the video, audio and subtitles of AVI files. It allows users to combine multiple video and audio files into one AVI file, as well as to split AVI files into multiple files. It also allows users to edit certain parameters of the AVI file, such as the frame rate, bitrate and resolution. Additionally, users can add subtitles to the AVI file, as well as insert and extract chapters. Finally, users can view and modify the header information of the AVI file, such as the author, title and copyright information.
