Pictures in video
Hello! This is my first post
I'm sorry if this has been answered but I don't really know how to ask the question. I'm trying to make a video in which I take some pictures of heads of some people and place them over the heads of the people in the movie. Sort of like a parody video. My issue is, and I'm very new at this, that I don't know how to make the picture that I place in the video to disappear when I need it to or change its size.
For example, the video I'm using is a clip of the Emperor's death in Star Wars and I have the face over the Emperor in the first frame, but then the camera changes to look at Luke in the next frame and the face is just hanging there in the air. Then it goes back to the Emperor and its a close up shot of him and its too small.
I hope that was a good enough explanation, I'm sorry if this is beginner level but this is my first time using this software. Just trying to make some funny videos and such. Thanks for your help!
