<p />
Cinelerra is a sophisticated audio/video Non Linear Editor that runs on Linux. 
<p />
Cinelerra is a complete editing tool, it can play, edit, cut, paste audio and video materials. Cinelerra also has editing features such as transitions and audio effects. Finally Cinellerra has a powerful compositor tool to create complex video effects. 
<p />
<h4><a name="What_is_NLE"> </a><a name="What_is_NLE_"> </a> What is NLE ? </h4>
In contrast to linear editing where film is actually cut and pasted in a "linear" manner to compose a film, a 
non-linear editing system is a video or audio editing system that can read media materials in any order, then allowing for one to create a "editing lists" telling the system wich segments get played independantly of the order of the original material.  An important feature of modern NLE's is that the original material is not modified in any way, that is why it can also be called a Non-Destructive Editing system. 
<p />
<img src="../../../pub/TWiki/TWikiDocGraphics/help.gif" border="0" alt="HELP" width="16" height="16" /> For a more coplete definition of NLE look at <a href="http://en.wikipedia.org/wiki/Film_editing" target="_top">http://en.wikipedia.org/wiki/Film_editing</a> on wikipedia.

Cinelerra is both an editor and a compositor.  It lets you do both cutting
and layering/mixing at the same time.  This means the <a class="twikiLink" href="TimeLine">TimeLine</a> is rather
packed with features.  Some of those features are not visible or obvious,
e.g. the <a class="twikiLink" href="KeyFrame">KeyFrame</a>.  Compositing is more relevant to the professional or
the advanced amateur.

<h3><a name="About_Cinelerra"> </a> About Cinelerra </h3>
<p />
(From the authors manual) 
For years some people have wanted a way to edit their audio and video in one place as fluidly as writing text. <strong>Cinelerra</strong> tries to be a single location for all audio and video editing needs. All the recording, editing, and playback are handled here. It can be used as an audio player. It can be used to record audio or video. It can even be used as a photo retoucher.
<p />
There are two types of moviegoers: producers who create new content, going back over their content at future points for further refinement, and consumers who want to acquire the content and watch it. <strong>Cinelerra</strong> is not intended for consumers. <strong>Cinelerra</strong> has many features for uncompressed content, high resolution processing, and <a class="twikiLink" href="Compositing">compositing</a>, with very few shortcuts. Producers need these features because of the need to retouch many generations of footage with alterations to the format, which makes <strong>Cinelerra</strong> very complex. There are many more standard tools for consumers like <span class="twikiNewLink" style="background : #FFFFCE;"><font color="#0000FF">MainActor</font><a href="http://www.ftconsult.com/twiki/bin/edit/Cinelerra/MainActor?topicparent=Cinelerra.WhatIsCinelerra"><sup>?</sup></a></span>, Kino, or Moxy, which you should consider before using <strong>Cinelerra</strong>.
<p />
In 1996 our first editor came out: Broadcast 1.0. It was just a window with a waveform in it, it could cut and paste stereo audio waveforms on a UNIX box, except unlike other audio editors it could handle files up to 2 gigabytes with only 64 megs of RAM. That was a feature normally only accessible to the highest end professional audio houses.
<p />
In 1997 Broadcast 1.0 was replaced by Broadcast 2.0. This time the window had a menubar, patchbay, console, and transport control. Broadcast 2.0 still only handled audio but this time it handled unlimited tracks, and it could perform effects on audio and save the resulting waveform to disk. More notably a few effects could be performed as the audio was playing back, in realtime. A user could mix unlimited numbers of tracks, adjust fade, pan, and EQ, and hear the result instantly. Amazingly this real time tweeking is still unavailable on most audio programs.
<p />
But Broadcast 2.0 still didn't handle video and it wasn't very graceful at audio either. In 1999 video broke into the story with Broadcast 2000. This iteration of the Broadcast series could do wonders with audio and offered a pretty good video feature set. It could edit video files up to 64 terabytes. It could do everything Broadcast 2.1 did with audio except now all effects for video and audio could be chained and performed on the fly, with instant feedback as a user tweeked parameters during playback. Broadcast 2000 made it very easy to do a lot of processing and editing on video and audio that would otherwise involve many hours setting up command line sequences and writing to disk. For a time it seemed as if the original dream of immersive movie making for everyone regardless of income level had arrived.
<p />
Later on Broadcast 2000 began to come short. Its audio and video was graceful if you knew how to use it efficiently, but quality issues and new user interface techniques were emerging. Broadcast 2000 kept the audio interface from its ancestors, which didn't apply well to video. Users likewise were maturing. No longer would it be sufficient to just edit video on a UNIX box. Most users expected on UNIX the same thing they got in Win or Mac. In mid 2000 designs for a Broadcast 2000 replacement were drafted. The Broadcast name was officially retired from the series and the software would now be called <strong>Cinelerra</strong>. <strong>Cinelerra</strong> would allow users to configure certain effects in much less time than required with Broadcast 2000. It would begin to emulate some of the features found in Win and Mac software while not attempting to become a clone. It's interface would be designed for video from the ground up, while supplementing that with the Broadcast audio interface. As always, quality improvements would happen.
