Hey guys, I'm needing a bit of help on the newest version of iMovie (10.0.8), I have a short clip I'm using for work, and I need to pixelate or blur or chuck something on top of the face of the person in the video (young person who doesn't want his face to be shown), I can't figure out any way of doing it, any guides I've read on how to do it using picture in picture etc are for older versions which have different menu's etc, if anyone could help me to do it on the newest version that would be great, thanks!
