Cinelerra is a video editing and compositing software package. It is designed for the Linux operating system. It is produced by Heroine Virtual, and is free software distributed under the GNU General Public License. Cinelerra also includes a video compositing engine, allowing the user to perform advanced compositing operations such as keying and mattes.

Cinelerra was first released August 1, 2002, and was based in part on Broadcast 2000, which was withdrawn by Heroine Virtual in September 2001. Cinelerra became the first 64-Bit media production application when it was re-written to conform to the AMD Opteron in June 2003 and was presented at SIGGRAPH 2004 in San Diego. This version was subsequently released by Adam Williams of Heroine Warrior, the principal developer of Cinelerra.

Cinelerra has a wide range of features including support for 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. It is resolution and frame rate-independent, meaning that it can support video of any speed and size.

Cinelerra's interface is similar to that of other Non-linear editing systems, such as Adobe Premiere Pro, Final Cut Pro, and Avid Media Composer. However, because it includes a compositing engine, it may also be likened to compositing software such as Adobe After Effects, Smoke on Linux or Shake. The user is presented with four screens:
