Hello everyone.
I’m currently working on a sci-fi pilot and I’m having trouble with this shot. It requires a sky replacement and the addition of some alien fighter jets flying overhead.
The director and I are happy with the sky replacement, but I’m having trouble with the fighters. They look OK when viewed as a still frame but, when they are in motion, they look wrong, but I don’t know why. Here are some before and after frames:
And here is the video:
I would be extremely grateful for any help you can give me to make the fighters look better.
Many thanks.
