t'ho dico per flasciotto:

considero lolll il tuo movie che vuoi trasformare in bianco e nero...

import flash.filters.BitmapFilter;
import flash.filters.ColorMatrixFilter;

var cambio:Array = new Array();

cambio = cambio.concat([0.212671,0.71516,0.072169,0,0]);
cambio = cambio.concat([0.212671,0.71516,0.072169,0,0]);
cambio = cambio.concat([0.212671,0.71516,0.072169,0,0]);
cambio = cambio.concat([0, 0, 0, 1, 0]);

var filtro:BitmapFilter = new ColorMatrixFilter(cambio);

lolll.filters = new Array(filtro);
