It is used by video editors Kdenlive, OpenShot and Shotcut among others.
Technical overview
MLT provides an API with minimal dependencies (POSIX and C99). The design is modular allowing for the addition of new components and making integration simple with other multimedia libraries and applications. Support is available for the authoring and manipulation of time-based media including playlists, multiple tracks, filters, and transitions using DOM.
High-level language bindings exist for C++, Java, Lua, Perl, PHP, Python, Ruby, and Tcl. MLT takes advantage of multi-core processors and GPU processing.
MLT has a modular design that supports multiple libraries like FFmpeg and Jack. Through FFmpeg, MLT is able to support nearly all audio and video formats with optimized operations. Video and audio effects include image scaling, alpha-compositing, deinterlacing, masking, motion-tracking, audio mixing, audio gain, and wipe transitions.
