I am thinking of doing a sequence in which the subject appears to walk through a glass door without stopping. In addition, I would want to lower the opacity of the subject's layer to apply a "ghost effect."
For the most part, I've decided on using a static angle, as a moving camera would make the editing much more difficult.
Right now, this is what I've come up with in terms of a shot list:
1) Empty frame, without a subject (door closed)
2) Subject walking through (door open)
I was thinking of masking out the closed door in shot 1 and placing it in the second shot, but I don't think that will accomplish what I want. I'm not sure how to make the transition from one side of the glass door to the other in order to make it look convincing.
Any suggestions on how to achieve this effect would be greatly appreciated.
