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 the GTK+ or Qt.

Contents

[edit] 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”).

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 subtitle. 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.

[edit] 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 is a person known as Mean, who often frequents the Avidemux.[5] The Avidemux project is open to user input and many suggestions from its users have already been implemented as fully written features.

[edit] Multithreading

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

[edit] Versions and ports

The current stable version of Avidemux is 2.5.3. Compared to the 2.3 and earlier versions, Avidemux 2.4 offers 3 user interfaces: GTK+, shell and Qt 4.

Avidemux is available for almost all distributions of Linux 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.[6][7][8]

[edit] Comparison

Avidemux can be compared with VirtualDub or VirtualDubMod. While it cannot do everything that VirtualDub can, Avidemux can do things that its Windows-only counterpart cannot. It has native support for OGM, MP4 and Matroska files, direct read input for various types of MPEG files, and many other video formats and containers. It offers MPEG editing and requantization. It also has built-in subtitle handling.

Avidemux's features and functions are comparable to VirtualDub, but it has also been criticized for a poor user interface. Due to Avidemux's multithreading features and native support for x86-64, it was capable of outperforming VirtualDub in certain respects for several years.

Avidemux primarily uses its GUI to perform tasks. This means that it is capable of doing many things that non-GUI users would otherwise have to do using command line tools such as MEncoder or Transcode.
