LiVES (LiVES Editing System) is a free video editing software and VJ tool, released under the GNU General Public License version 3 or later.[1] There are binary versions available for most popular GNU/Linux distributions (including Debian, Ubuntu, Fedora, Suse, Gentoo, Slackware, Arch Linux and Mandriva). There are also ports for BSD, and it will run under Solaris and IRIX. It has been compiled under OS X Leopard, but not thoroughly tested on that platform[2]

Development

The main developer of LiVES is Gabriel Finch (a.k.a. Salsaman), who is also a video artist and international VJ.

The project began in late 2002, and the 1.0.0 version was released in July 2009.

On the Freecode site, LiVES is listed as the most popular non-linear video editing software.[3]

LiVES was nominated for the category of Best Project for Multimedia in the Sourceforge Community Choice Awards 2009.

The LiVES application allows the user to manipulate video in realtime and in non-realtime. The application also has features which go beyond traditional video editing applications - for example, it can be controlled and monitored remotely over a network, and it has facilities for streaming to and from another copy of LiVES. It is resolution and frame rate independent.

LiVES uses a system of plugins for effects, decoders, encoders and video playback. The APIs for these are now well defined, and the application can be easily extended.

Interface

LiVES has two main interfaces: the clip editor, which serves as a repository of video and audio material, and the multitrack window, where multiple clips can be positioned on the timeline.

The clip editor allows free playback at variable play rates, applying of multiple realtime effects and mixing of clips. This mode is mainly used by VJs. Video editors can also use this interface to prepare the clips before entering into multitrack mode.

In multitrack mode, the individual clips can be arranged in layers on the timeline. Further effects and transitions can be applied here, and the audio can be mixed down. The entire timeline can then be rendered, creating a new clip.

Rendering previews are shown in real time.

Features

The LiVES Multitrack Window

LiVES' features include:

  • Loading and editing of almost any video format (via mplayer decoder).
  • Some formats can be opened instantly using decoder plugins (e.g. flv, asf, dv, webm and ogg/theora).
  • Smooth playback at variable frame rates, forward and in reverse. Display framerate can be controlled independently of playback framerate.
  • Frame accurate cutting and pasting within and between clips.
  • Saving/re-encoding of clips, selections, and individual frames.
  • Lossless backup/restore.
  • Streaming input and output.
  • Real time blending of clips (various chroma and luma blends).
  • Can handle in/out streams in LiVES to LiVES or yuv4mpeg format. Streams can be piped from stdout into other applications.
  • Support for live firewire and TV card inputs.
  • Internal support for RGB24, RGBA32, YUVA, YUV, YUV422, YUV420 (jpeg and mpeg), YUYV, YUV411, and UYVY palettes; one step conversion with chroma super and subsampling is implemented.
  • Ability to edit many filetypes and sources including remotely located files (with mplayer/ffmpeg libraries), and directories of images (rotoscoping).
  • Real time capture/recording of interactive (via mouseclicks) external windows.
  • Encode to any of the 50+ output formats which are now supported (e.g. mjpeg, mpeg4, mpeg1/2, h264, webm, VCD, SVCD, DVD, x264/blu-ray, ogg/mp4 ogm, Matroska mkv, dv, swf, Ogg Theora, Dirac, MNG, Snow, xvid, Flash and even animated GIF and PDF)
  • Resampling of video (time stretching) to any frame rate (1 to 200 frame/s - accurate to 8 decimal places); option to auto-resample or speed up/slow down between clips.
  • Rotation, resizing and trimming of video clips.
  • Deinterlacing, subtitle removal. Auto deinterlacing for dv can be enabled.
  • Can load mp3, vorbis, mod, it, xm and wav audio files.
  • LiVES can also load audio tracks directly off CD to use with video.
  • Sample accurate cutting and pasting of audio within and between clips.
  • Resampling of audio (rate, channels, sample size, signedness and endianness); audio is auto-resampled between clips.
  • Able to record from any external audio source.
  • Fade in/fade out feature for clips.
  • Audio speed and direction can be smoothly adjusted; both in real time and when rendering.
  • Hundreds of effects, including random/targeted zooming, panning of video, colour cycling and colorisation/colour filtering and colour correction.
  • LADSPA support for audio effects.
  • Merging/compositing of frames is possible: e.g. frame-in-frame, fade in/out and transparency.
  • Real time previews as the effect is processing.
  • Support for the Frei0r 1.1 and 1.2 effect plugin architectures, libvisual plugins, and projectM plugins.
  • Multiple real time effects are possible during playback (VJ mode), these can also be rendered to frames.
  • Multitrack window with drag and drop
