Avidemux is a free and open-source video editing program designed for video editing and video processing. It is written in C++, and uses either GTK+ or Qt for its user interface.

Features

Avidemux is capable of non-linear video editing, applying visual effects (called "Filters" by Avidemux) to video, and transcoding video into various formats. Some of the filters were ported from MPlayer and Avisynth. Avidemux can also insert audio streams into a video file (an action known as multiplexing or "muxing") or extract audio streams from video files (an action known as "demuxing").

Avidemux supports many formats, such as AVI, MP4, Matroska, MPEG-2, H.264 and H.265. It does not yet, or only partially supports modern open formats, like Opus, WebM, VP8, VP9 and AV1.

An integral and important part of the design of the program is its project system, which uses the SpiderMonkey JavaScript engine. Whole projects with all options, configurations, selections, and preferences can be saved into a project file. Like VirtualDub's VCF scripting capabilities, Avidemux has advanced scripting available for it both in its GUI and command line modes. It also supports a non-project system just like VirtualDub, where users can simply create all of their configurations and save the video directly without making a project file. A project queue system is also available.

Avidemux has built-in subtitle processing, both for optical character recognition of DVD subtitles and for rendering hard subtitles. Avidemux supports various subtitle formats, including MicroDVD (.SUB), SubStation Alpha (.SSA), Advanced SubStation Alpha (.ASS) and SubRip (.SRT).

While it is primarily a GUI program, Avidemux can also be run from the command line.

Components

Avidemux was written from scratch, but additional code from FFmpeg, MPlayer, Transcode and Avisynth has been used on occasion as well. Nonetheless it is a completely standalone program that does not require any other programs to read, decode, or encode other than itself. The built-in libavcodec library from the FFmpeg project is used for decoding and encoding of various audio and video formats such as MPEG-4 ASP. The primary (though not the only) Avidemux programmer uses the nickname 'Mean' on the Avidemux forum.[3] The Avidemux project is open to user input and many suggestions from its users have already been implemented as fully written features.

Multithreading

Multithreading has been implemented in the following areas of Avidemux (some partially through libavcodec):

Versions and ports

Avidemux is available for almost all Linux distributions that are capable of compiling C++, GTK+ and the SpiderMonkey JavaScript engine. A Win32 version of this program is also available for Microsoft Windows users, as well as Mac OS X, FreeBSD, NetBSD and OpenBSD ports and packages.[4][5][6] Starting with version 2.4, Avidemux offers a command-line interface and two graphical ones: One based on GTK+ and another based on Qt. With version 2.6 the GTK+ version is unmaintained.
