WebVfx is a video effects framework that allows video effects (filters, transitions etc.) to be authored using web technologies (HTML, CSS, JavaScript, WebGL etc.) or with Qt Quick QML (a declarative CSS and JavaScript like language). See Effects Authoring for documentation and samples.

WebVfx includes plugins for the MLT open source multimedia framework. See MLT Plugins for information on how to use WebVfx with MLT.

Sample effects included with the distribution, and videos rendered using them with MLT can be viewed here:

WebVfx is hosted at github, see the README there for build instructions.
