The Editing of both Audio and Moving Images have always been the strong point for Cinelerra.  Keep in mind that Cinelerra operates on a floating point. So, with the right set-up of your system, you can be easily editing very high resolution film images at 2K and 4K in real-time on Free Software. 



CINELERRA, the revolutionary Linux based Open Source HD media editing system, can provide the editing and processing power to perform the most advanced media editing tasks.  CINELERRA is a powerful and highly productive system when configured correctly on the right system


CINELERRA, the first Linux based  real-time editing and special effects system is a revolutionary Open Source HD media editing system. Cinelerra supports real-time 1080p, 1080i, 720p, 480p. and h.264 HD & SD profile editing and effects processing.  The first Non-Linear editing system developed for 64 Bit technology technology, the CINELERRA system is  a powerful and highly productive workstation  for  video and film production studios.

CINELERRA has a number of effects built into the system including numerous telecine effects,  video special effects including composites of multiple layers,  and a complex audio effects system.

Seeing Wavelab producing real time reverb and EQ in 1997 was the inspiration for real time processing in Cinelerra. Today, most every operation can be done in realtime, including processing of the time domain, out of order.

Also, track bouncing, side chaining, and reuse of effects between multiple tracks has always been supported. Media can be played through the timeline, from the capture source.



Cinelerra supports OpenGL on some NVidia graphics cards, which greatly accelerates playback. This depends on the card & driver. The standard for GPU programming has shifted over the years between NC, GLSL, & CUDA. Intel & ATI/AMD had their own standards. Cinelerra was written in GLSL, which only worked in NVidia & now seems to be the minority.



Cinelerra does not support every codec ever invented, but it does support the most common WMV and FLV derivatives well enough to transcode them into a format suitable for editing. Most formats can be edited straight off the DVD, Blu-ray, or original file, without transcoding. The format that all your favorite online video networks import, H.264 video + MPEG4 audio on Quicktime, is the standard export format.



For most operations on a modern computer, you can get comfortable speed without a renderfarm. But just so you know, it's there. Renderfarm is supported for rendering and background rendering, creating a theoretically unlimited maximum speed.

The biggest difference between this renderfarm and normal renderfarms is you don't need to pay for node licenses. You can keep installing nodes without paying for either the operating system or the application.



Store and retrieve images in the best possible fidelity with floating point imaging and file formats. Access OpenEXR, the official file format of Lucasfilm. Access CR2 images from Canon EOS digital cameras in floating point. Adjust color levels without losing information. Never have to guess how far out of range the colors are. Save high dynamic range intermediates for multiple steps without losing data.



Since it's Linux, it's been 64 bit compliant for years. In fact, Cinelerra is only tested in 64 bit mode. The reason is the large amount of virtual memory required for page flipping and floating point images often exceeds the limit of 32 bits.
