Mac Forums

i shoot super 8 movie film, and i just shot some vision 2 negative film. Previously i was using my web cam and imovie with my colour positive film, but now that i used negative film i dont know how to alter the colours to positive. I can send it out and get someone to do it for me, but it adds up to quite a bit, so i was wondering if anyone knew a program that could change the colours around, weather for PC, or mac, i have both.
now it has to be for motion picture, it cant just be for still pictures, i have a program for still pictures.
