Hello. I would like to make a video, where an actor would have a sign on his back saying for example looser. Camera would focus just on the sign, nothing else would be able to be seen. Then I would like to change the text on the sign to something else. I was thinking about stop motion animation and draw everything, but I bet that there´ll be an easier way to do this . Thank you in advance.
