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. KDE's Kdenlive makes use of MLT, Frei0r effects, SoX and LADSPA libraries. By 18 October 2022, the initial goal of €15,000 had been met. On 20 September 2022, KDE began the first fundraising drive for Kdenlive, with the funds to be used to implement major features and bring Kdenlive up to the standards of more professional video editors.

The refactored version of Kdenlive was released on 22 April 2019 in the KDE 19.04 Applications release. Release of the refactoring version was originally planned for August 2018 in the KDE 18.08 Applications release. By December 2017 the refactoring became the main focus of the development team with the release of the first usable preview. In early 2017 the development team started working on a refactoring of the program, and by June 2017 a first preview was available. Port to KDE Frameworks 5 was finished with the release of 2015.04.0 as part of KDE Applications 5. Kdenlive started to plan a move into the KDE Projects and its infrastructure in 2014. Kdenlive 0.9.10 released on 1 October 2014 was the last KDE 4 release. This was completed with Kdenlive 0.7, released on 12 November 2008. The development of Kdenlive moved on from the K Desktop Environment 3 version (which wasn't originally made for MLT) to KDE Platform 4, with an almost complete rewrite.
