Ubuntu is composed of many software packages, the vast majority of which are distributed under a free software license. The only exceptions are some proprietary hardware drivers.The main license used is the GNU General Public License (GNU GPL) which, along with the GNU Lesser General Public License (GNU LGPL), explicitly declares that users are free to run, copy, distribute, study, change, develop and improve the software. On the other hand, there is also proprietary software available that can run on Ubuntu. Ubuntu focuses on usability, security and stability. The Ubiquity installer allows Ubuntu to be installed to the hard disk from within the Live CD environment, without the need for restarting the computer prior to installation. Ubuntu also emphasizes accessibility and internationalization to reach as many people as possible.

LiVES mixes realtime video performance and non-linear editing in one professional quality application.

Monday, June 7, 2010

LiVES (LiVES is a Video Editing System) is a free software video editing program and VJ tool, released under the GNU General Public License version 3 or later. There are binary versions available for most popular Linux distributions (including Ubuntu, Gentoo, Debian, Fedora Core, Suse, Slackware, Arch Linux and Mandriva). There are also ports for BSD, and it will run under Mac OS X/Darwin, Solaris and IRIX.

The main developer of LiVES is Salsaman (Gabriel Finch), 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 Freshmeat site, LiVES is listed as the most popular non-linear video editing software.

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.

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. dv 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, VCD, SVCD, DVD, ogg/mp4 ogm, Matroska mkv, dv, swf, Ogg Theora, Dirac, MNG, Snow, xvid, and even animated GIF and PDF!)
* Resampling of video (time stretching) to any frame rate (1 to 200 fps - 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 tracks directly off CD to use with your 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.
* 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 effect plugin architecture (via a wrapper) which allows sharing of realtime effects with other applications.
* Multiple real time effects are possible during playback (VJ mode), these can also be rendered to frames.
* Multitrack window with drag and drop
* Intelligent screen organisation - shows you only the information which is relevant, no more and no less
* Support for an almost limitless number of tracks and effects
* Non-destructive editing in the multitrack window, with multiple levels of undo/redo.
* Full automation/interpolation of effect parameters.
* Support for stereo backing audio track + stereo audio track per video track
* Automatic gain control
* Realtime mixing/previewing of audio
* Channel mixer volume control + fine grained, time variable per-channel volume and pan control.
* Auto-transitioning of audio with video.
* Full crash recovery.
* Configurable multi-monitor screen placement.
* Simple and intuitive menu layout.
* Remote monitoring and control (via Open Sound Control) of the application can be enabled
* VJ functions can be controlled via keyboard, joystick or MIDI controller
* I18N text support. Translations into at least French, Czech, German, Japanese, Dutch, Portuguese, Spanish, Italian, Russian, Turkish, Hungarian, Slovak, Simplified Chinese, Finnish, Ukrainian, Arabic, Estonian, Uzbek and Hebrew are included.
* Support for audio output through pulse audio.
* Support for audio output through jack.
* Jack transport support (master or client)
* Full integration with upcoming videojack standard
* RFX builder allows rapid prototyping of new effects, transitions, generators, utilities and tools. Custom RFX scripts can be exported to share with others or downloaded and imported. Test scripts are run in a sandbox to allow safe testing of new plugins.
* MIDI sequence synchronisation (start/stop).
* Shuttle controls for firewire cameras/recorders. Can grab from DV and HDV formats.
