My MP4Box GUI is a Graphical User Interface for the well-known command line tool mp4box. My MP4Box GUI, like mp4box, is freeware. Meaning that it is complete and functional software that does not require payment or other compensation (such as nags or advertising) for its use.
MP4Box is an MP4 muxer. It can import MPEG-4 video (H.264 or ASP, encoded for example with x264, DivX, Xvid, 3ivx or FFmpeg) and audio streams into the MP4 container. The end result is ISO compliant MP4 streams. It can also produce MPEG-4 Timed Text streams by importing subtitles formats such as srt. It can also split MP4 files into sections, which can be useful when transferring files to portable media players. MP4Box is part of the GPAC Project framework. It provides only a command line interface, and, for legal reasons, the author only distributes its source code.
