Cinelerra

From Academic Kids

Template:Infobox Software Cinelerra is a free non-linear video editing system for the GNU/Linux operating system. It is produced by Heroine Virtual, and is distributed under the GNU General Public License. Cinelerra also includes a video compositing engine, allowing the user to perform common compositing operations such as keying and mattes.

Cinelerra was first released August 1, 2002, and was based in part on an earlier product known as Broadcast 2000. Broadcast 2000 was withdrawn by Heroine Virtual in September 2001; Heroine Virtual cited legal liability concerns in the wake of litigation from the RIAA and MPAA and the costs involved in high-end video production.

Notable features

Cinelerra includes support for very high-fidelity audio and video: it processes audio using 64 bits of precision, and can work in both RGBA and YUVA color spaces, using floating-point and 16-bit integer representations, respectively. (The "A" in both color space notations stands for alpha channel.) It is resolution and frame rate-independent, meaning that it can support video of any speed and size.

Other features may be found on its features list (http://www.heroinewarrior.com/cinelerra.php3).

Cinelerra interface

Cinelerra's interface is similar to that of other nonlinear video-editing systems, such as Adobe Premiere Pro; however, because it includes a compositing engine, it may be also be likened to compositing software such as Adobe After Effects or Shake. The user is presented with four screens:

  1. The timeline, which gives the user a time-based view of all video and audio tracks in the project, as well as keyframe data for e.g. camera movement, effects, or opacity;
  2. the viewer, which gives the user a method of scrubbing through footage;
  3. the resource window, which presents the user with a view of all audio and video resources in the project, as well as available audio and video effects and transitions; and
  4. the compositor, which presents the user with a view of the final project as it would look when rendered. The compositor is interactive in that it allows the user to adjust the positions of video objects; it also updates in response to user input.

Cinelerra usage and awards

Cinelerra has gained ground among some GNU/Linux enthusiasts looking for a native GNU/Linux video editing system. Professional use is mostly promoted by Linux Media Arts (http://www.lmahd.com), whom sells Cinelerra as part of an integrated hardware and software package for video production.

At the National Association of Broadcasters' 2004 Electronic Media Show, Cinelerra was awarded Bob Turner's "MAKING THE CUT" award (http://enews.primediabusiness.com/enews/videosystems/v/138#cinelerra). The award is given to "the best and most exciting postproduction products seen at the convention" [1] (http://enews.primediabusiness.com/enews/videosystems/v/138#making_cut_awards).
