So I'm trying to make a character fly on key frames with Chroma Key, but i'm running into two problems.
1. Sometimes I can't start the character all the way off screen, and have them end all the way off screen. For some reason it will cut off on certain parts of the frame.
2. Sometimes I'm getting a black line at the top and bottom of the image I'm chroma keying into the video, and if i try to crop these out it limits the area I can have the character fly.
