Trying to finger out how to best emulate an effect I saw on "The Vampire Diaries." It's a static frame with one character zipping across a room with lightning speed. Just a blur, really. (Cut to: Usually to pin some other character against a wall and say something menacing.)
Thought about shooting a static second or two then, without moving the camera shoot the character running across the room and ramping up in motion and pulling a mask in AE. But that's a serious ramp, and there's a blur and trails involved. I don't know. Just started thinking about it. Anyone know the effect I mean, and have any ideas?
Shoot the room (non moving camera.) Let everyone react, etc. Clear the actors off screen.
Have your actor walk through the screen with two people holding a greenscreen behind your actor. You'll get perfect perspective and lighting (well, decent lighting - it'll make the key hard), but now you have them moving perfect through the space.
Then all you have to do is use a keyer and garbage matte out everything else.
