Effect: Flicker

Description
Simulates the flickering due a bad projector lamp, or due to a bad camera's uneven speed.

Controls

Frequency:		The speed at which the flicker changes between frames.
Intensity:		The variation in the flicker intensity. A high value will cause some frames to appear very dark.
Brightness:		Sets the overall brightness of the clip. This is used to compensate for frames appearing dark due to the flickering.
Effect In/Out:		Animates the Intensity.

Notes
There are two ways of using this effect. If you want to simulate a bad projector, then you should apply this effect after all other scratch and dirt effects. If you want to simulate a problem at the camera, you should apply it before the other effects.

A subtle use of this effect, along with {Dark Corners}, combined with diffusion on a high contrast black and white clip, gives the impression of old Charlie Chaplin style film.
