Flowblade Movie Editor is a multitrack non-linear video editor for
Linux released under GPL 3 license.

It is designed to provide a fast, precise and as-simple-as-possible
editing experience.

It employs film style editing paradigm in which clips are usually 
automatically placed tightly after the previous clip - or between two 
existing clips - when they are inserted on the timeline. Edits are fine 
tuned by trimming in and out points of clips, or by cutting and 
deleting parts of clips. Film style editing is faster for creating 
programs with mostly straight cuts and audio splits, but may be slower 
when programs contain complex composites unless correct work flow is 
followed.

Optional recommended dependencies are swh-plugins, calf (and any other
JACK-compatible plugins), jack-audio-connection-kit.
