KDE's Kdenlive makes use of MLT, Frei0r effects, SoX and LADSPA libraries. Kdenlive supports all of the formats supported by FFmpeg or libav (such as QuickTime, AVI, WMV, MPEG, and Flash Video, among others), and also supports 4:3 and 16:9 aspect ratios for both PAL, NTSC and various HD standards, including HDV and AVCHD. Video can also be exported to DV devices, or written to a DVD with chapters and a simple menu.[6][7]
Kdenlive has multitrack editing with a timeline and unlimited number of video and audio tracks.
Tools to create, move, crop and delete video clips, audio clips, text clips and image clips. Configurable keyboard shortcuts and interface layouts.
A wide range of effects and transitions. Audio effects include normalization, phase and pitch shifting, limiting, volume adjustment, reverb and equalization filters amongst others. Video effects include options for masking, blue-screen, distortions, rotations, colour tools, blurring, obscuring and others.
Ability to add custom effects and transitions.
Rendering is done using separate process so it can be stopped, paused and restarted and is non-blocking.
Kdenlive also provides a script called the Kdenlive Builder Wizard (KBW) that compiles the latest developer version of the software and its main dependencies from source, to allow users to try to test new features and report problems on the bug tracker.[8]
The project was initially started by Jason Wood in 2002. The development of Kdenlive moved on from the K Desktop Environment 3 version (which wasn't originally made for MLT) to KDE Platform 4, with an almost complete rewrite. This was completed with Kdenlive 0.7, released on November 12, 2008. [9] As of March 1, 2015, Kdenlive is undergoing a port to KDE Frameworks 5. [10]
