Kdenlive

A free and open-source video editing software built with KDE and Qt. Kdenlive was first created and released back in 2002 by Jason Wood. Since then the software has seen massive traction in the open-source community. Kdenlive allows you to use and arrange several audio and video tracks, each one can be locked or muted to your convenience. Since Kdenlive is based on the powerful FFmpeg libraries the software can handle most audio and video formats needed to convert and re-encode clips. To top it up Kdenlive also provides plenty of effects, ranging from color correction to audio adjustments, as well as all the standard transform options.
