Please have a look at this little vid [~0.5M, not mine].
At around 2 sec there is a transition between shots where someone walks past the camers.
I would like to know how to do this in Premiere or After Effects.
The only way I can think of doing it is keyframing a green screen at the same place as the walker, and super-imposing over the green screen, but there 'must' be an easier way.
Thanks in advance...
