Introduction to effects
Pitivi offers a wide variety of video and audio effects to spice up your movies. Available effects depend on the software installed on your computer. If you don't see anything (or only a handful of effects) in the effect library, make sure that the gnome-video-effects package is installed on your system. Alternatively, you can look for packages containing GStreamer or frei0r effect plugins that are available in the repositories of your distribution.
Effects are non-destructive: they are only applied to the resulting rendered movie and do not affect your source files.
