“First, the bare-metal description. Kdenlive (Figure 1) is a
non-linear video editor for Linux, FreeBSD, and OSX. It supports
realtime input from camcorders (DV, HDV, professional, etc),
cameras capable of MPEG4 and H264 output, and standard
USB-compliant webcams (some of them, that is). File I/O is
supported for a variety of video and audio codes and formats,
including AVI, MPEG, FLV, raw DV, WAV, and many others. Kdenlive’s
editing features include a track-based A/V mixer, effects and
transitions processing, keyboard accelerators, and non-blocking
rendering. Of course all common editing operations are also
supported, e.g. cut/copy/paste, splicing, track solo/mute, and so
forth.“Kdenlive is software libre licensed under the GPL. It leverages
the power of other free software projects such as Qt4, MLT, and
FFmpeg, and it requires the base libraries for KDE, though you do
not need to run the KDE desktop. Pre-compiled packages are
available for various Linux distributions, and all source code is
freely available.”
