A professional quality Non-linear video editing suite for Linux (KDE) - Kdenlive

Kdenlive is a non linear video editor for the KDE desktop environment. The software provides project management and editing tools while relying on a separate rendering program to perform the editing operations.

It is based on the MLT video framework which relies on the FFmpeg project.

Kdenlive Support is planned for transitions, effects, multiple file formats, and full project and asset management support. The current beta release is capable of editing raw DV or AVI DV files, with tools such as move, razor, and resize, selecting parts of clips using in/outpoints, and exporting the result to another raw DV file.

Kdenlive supports all of the formats supported by FFmpeg (such as MOV, AVI, WMV, MPEG, XviD, and FLV), and also supports 4:3 and 16:9 aspect ratios for both PAL, NTSC and various HD standards, including HDV.

Video can also be exported to DV devices, or written to a DVD with chapters and a simple menu.

  * Multi track editing
  * Video Preview
  * Accepts many audio / video / image formats: mpeg, avi, dv, vob, wav, ogg, mp3, gif (non animated), jpg, png, svg, ...
