Shotcut
# Shotcut

Shotcut is a free and open-source, cross-platform video, audio, and image editing program for FreeBSD, Linux, macOS and Windows. Started in 2011 by Dan Dennedy, Shotcut is developed on the MLT Multimedia Framework, in development since 2004 by the same author.

## Features

Shotcut supports video, audio, and image formats via FFmpeg. It uses a timeline for non-linear video editing of multiple tracks that may be composed of various file formats. Scrubbing and transport control are assisted by OpenGL GPU-based processing and a number of video and audio filters are available. The output options for the 2017 version included Apple ProRes, HDV, DVD, Flash, H.264, GIF animation, Ogg-Vorbis, WebM, and WMV.

## History

Shotcut was originally conceived in November 2004 by Charlie Yates, an MLT co-founder and the original lead developer. The current version of Shotcut is a complete rewrite by Dan Dennedy, another MLT co-founder and its current lead. Dennedy wanted to create a new editor based on MLT and chose to reuse the Shotcut name, since he liked it so much. He wanted to make something to exercise the new cross-platform capabilities of MLT, especially in conjunction with the WebVfx and Movit plugins.
