Using paint to key?
Hi
I was just wondering if anyone knows if it’s possible to use paint as a keying tool? What i am trying to do is take a section of something, remove it and replace it with a different image. I have tried using animated masks, but i can’t seem to animate the masks too such a convincing degree that it that it cancels out the other image. Because it is moving footage i wondered if anyone knew a way to use paint to as a keying tool?
Cheers
Vincent

Bill O’neil wrote a tutorial on this. Search the archives for “rotoscoping with vector paint” or something like that. Very useful.

If you are talking about the physical substance of paint, such as in a can of paint. I have used it many times. once had a white card at an angle and poured paint onto it above the camera sight and let it run down til the screen was filled. I also used it once to key from the center by taking a half ball, drilling a hole into it using a plastic tube pumped paint out the top and let it run down all sides til it filled the screen. There are many ways to use paint.
Hope this is what yuo were talking about, and it helps. Oh by the way the first time was about 35 years ago. You had to improvise a lot back then for some effects.
