is there a good (and afordable) program to edit out faces on video. Have some great footage of wife with a g/f, but she doesnt want her face on internet. her husband doesnt know...

I also have some really hot videos I'd love to share but hiding the face is the problem. I'll take any advice I can get too.

Depends what you mean by "affordable"
