PiTiVi offers a wide variety of video and audio effects to spice up your movies. Effects are non destructive: they are only applied to the resulting rendered movie and do not affect your source files.
Available effects depend on the software installed on your computer. If you don't see anything (or only a handful of effects) in PiTiVi's effect library, make sure that the following are installed on your system:
To add an effect:
Select an existing clip on the timeline
Choose an effect in the effect library
Drag the chosen effect into the Clip configuration pane's Effects section
To remove an effect on a selected clip, select it in the clip's effect list and click the Remove button.
If you want to temporarily disable an effect (to compare with and without the effect, or for performance reasons), click the corresponding checkbox in the effect properties pane.
