Cinelerra for Linux does primarily three things, which is capturing, composting, and editing audio and video with sample level accuracy. It is a movie studio in a box. Cinelerra supports OpenGL shaders on NVidia graphics cards. The video crunching power that was once exclusively the domain of SGI minicomputers is now yours. 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.
