Negate b/w 1.3.0

Negate b/w is an iMovie plug-in that converts a plug into bw and in the same pass lets you invert it (make a negative film).
You can choose the ’invertness’ of the clip, thus Negate b/w has actually two plugs in one: the good old ‘black & white plug (although this time around you can - as with all our plugs - specify the area that should be converted), and the invert plug (except that you can set how much inversion you want).
Use it whenever you need to only convert parts of your clip into b/w, and whenever you need a b&w negative part of your clip (we know that - unless you are into signal processing - the latter doesn’t happen that often. it’s a cool plug nonetheless...)
Main features:
area of effect :
- define the area of the clip you want to be affected by the plug-in. all other parts of the clip remain untouched.
negate:
- use this slider to select inversion. left means no inversion, right means full inversion. a 50% inversion will (of course) always set all pixels in this clip to a value of 50% (the midpoint of an image is always a 50% gray).
