[edit] Description

Ghostbuster is an AviSynth filter for removing "ghosts" from a clip. A ghost in this context is a faint copy of the picture offset horizontally. It works by either subtracting or adding the image from itself at the specified offset. With some tweaking the result, while not perfect, can be very pleasing. (That is to say, Ghostbuster is basically a YUY2 AviSynth implementation of the Exorcist VirtualDub filter by Chris Wojdon. It should be parameter-compatible. See his site.)

[edit] Syntax and Parameters

Ghostbuster (clip, int "offset", int strength")

clip   =
Input clip.

int  offset = 3
A positive offset indicates the ghost copy is that many pixels to the right; negative, that many pixels to the left. A zero offset is invalid.

int  strength = 10
The strength (-100 to 100, but not zero) indicates the intensity of the ghost copy. Whether the strength is positive or negative determines whether the image will be added or subtracted, respectively, from itself. This is somewhat hard to explain, but the effect is easy to see. Experiment!

[edit] Examples

Ghostbuster with default settings:

Ghostbuster (offset=3, strength=10)
