How to superimpose an image over a video?

[powerbuddy]

I have FCE 4.0 and both iMovie. I have seen many of these youtube videos where they superimpose an image of a face, over the original face in a video. Does anybody have an idea how to do this?

In FCE, place the background video on track V1 then place the image to be overlayed on track V2. You'll have to keyframe the positioning (center) of the image to match the movement of the subject in the background video.

If the image is too large, you'll need to adjust it's scale also.

I get all that..but how do i keyframe the motion of the center? Is there any tutorial on that?

There are commercial plugins that wil scan your clip and attempt to track
an object given you you outline what you want to track at the start and end.

(example: http://www.chv-plugins.com/motion.html )

You can just do it manually of course: Set your start and end key frames on V2, play the clip to see how bad it is off. Set you next keyframe in the *middle* of the start and end, and correct where the object "should" be... play it through... go to the middle of *that* and set another keyframe. Rinse, repeat.

You'll want to read this website as well:

( particularly the section on motion )

Good luck!

I would do this in AE but it can be done in motion pretty easily.

Sorry didn't see that you had FC4. I've got to learn to read the entire post.

hunters fix is a great one.
