Ubuntu Linux

Having Avidemux on Flathub is a much needed addition, since it was removed from Debian and Ubuntu (with Ubuntu 16.04), leaving users to rely on building the software from source, or using third-party repositories, which is not always a good idea for audio / video software (because in some cases they require newer dependencies like FFmpeg and others, which may affect repository-installed apps).

Avidemux is a free open source software for video editing and processing, created for simple operations, that's available for Windows, macOS and Linux. Use it to perform video editing operations like cutting, encoding, filtering (apply visual effects), add audio to video files (multiplexing or muxing) or extract audio from some video.
