Kdenlive: a free and open-source video editor for Linux

Kdenlive is a free open-source video editor for GNU/Linux and FreeBSD, which supports DV, AVCHD and HDV editing. Kdenlive relies on several other open source projects, such as FFmpeg, the MLT video framework and Frei0r effects.

Powerful features

Kdenlive is the most versatile video editor available today:

• Support for a wide range of camcorders and cameras, including:
  1. Low resolution camcorder (Raw and AVI DV editing).
  2. Mpeg2, mpeg4 and h264 AVCHD (small cameras and camcorders).
  3. High resolution camcorder files, including HDV and AVCHD camcorders.
  4. Professional camcorders, including XDCAM-HD™ streams, IMX™ (D10) streams, DVCAM (D10) , DVCAM, DVCPRO™, DVCPRO50™ streams and DNxHD™ streams (decoding only, encoding untested). Please note that Kdenlive does not offer the original codecs, but only that we use FFmpeg free software codecs, which can read original streams and sometimes export as well. When you own a camcorder, there is no reason why you should not be able to read your own films.
