Free video conversion software

FFmpeg is a free and open-source software project consisting of a suite of libraries and programs for handling video, audio, and other multimedia files and streams. At its core is the command-line ffmpeg tool itself, designed for processing video and audio files. It is widely used for format transcoding, basic editing (trimming and concatenation), video scaling, video post-production effects, and standards compliance (SMPTE, ITU).

Avidemux is an application for non-linear video editing and transcoding multimedia files. The developers intend it as "a simple tool for simple video processing tasks" and to allow users "to do elementary things in a very straightforward way". It is written in C++ and uses Qt for its graphical user interface (GUI), and FFmpeg for its multimedia functions. Since version 2.4, it has two user interfaces: a GUI and a command-line interface. Since version 2.6, the original GTK port has been unmaintained and is now discontinued. It is free and open-source software released with a GNU General Public

HandBrake is a free and open-source transcoder for digital video files. It was originally developed in 2003 by Eric Petit to make ripping DVDs to a data storage device easier. HandBrake's backend contains comparatively little original code; the program is an integration of many third-party audio and video libraries, both codecs (such as FFmpeg, x264, and x265) and other components such as video deinterlacers (referred to as "filters"). These are collected in such a manner to make their use more effective and accessible (e.g., so that a user does not have to transcode a video's audio and visual
