I'm working on a title sequence, basically there's a background still, and a bitmap logo which I want the camera to reverse through, you know, very much done before camera looking 'backwards' flies through text in space.
So I've created the logo with a green surround, keyed it, stuck motion controls on it (a pain that zoom can only go to 600%, need more, but can sort that), it's working just as I want, except when the edge of the logo image comes into frame it can be seen, a pixel wide flashing as it zooms out. I've checked the image, fine.
I can remove it using 'edge thin', but that trashes the image itself, I've tried various combinations of the settings but whatever I do the image is compromised.
Is this simply a question of using a huge background so that the edge doesn't come into the frame before it's faded out?
Or, is it wise to choose a background colour that is as far away from the logo as possible? I asked because the logo is yellow, and I went for a green screen key, right next to each other. Would, say, a purple be better so that I can adjust the tolerance more to remove these edges?
I'm answering my own question aren't I
