hello, im looking to make a video for my brother, but what i would like to do, is using a picture of his face, to cut out the mouth, and then put my mouth in its place, to make it look as though he's speaking?! if that makes sense. if anybody has seen soccer am in the uk, or similar tv programmes, they do it on there!

what id like to know is, whats the best program to do something like this, and how would i go about doing it!

any help is muchly appreciated.

thank you
