Hi all, I'm trying to pixellate an image of a face on a video using
Premier.I load the original video on the Vid.1 track & copy the same on
Vid.2 track. I then use the effects filter "pixellate" and drag it to the
Vid.2 track and choose the degree of pixellation.so far so good. all of
the video on track 2 is pixellated. now I choose "crop" in the Transform
folder and grag it onto the Vid.2 track.But when I try to minimize the
pixellate effext to cover only the face the program can not do it.what it
does is it just streches the video image horizontal and vertically,
instead of zooming to a specofic area.I wish u guys would help.I've done
just about everything except seeking help from you guys and gals.Thanks so
much.Karla
