Opacity Question, second layer is transparent?
Hello, I have a guy sleeping on the left side of the frame, then he wakes up and walks to the right side of the frame while his sleeping body is still laying there. Pretty sure most of you out there have done this. The clip on the top is him walking and is set at about 60 percent opacity, and the video underneath shows part of this transparente clip above it making the sleeping guy seem transparent. Is using a matte here the direction I should go with.

As I understand, it’s doing exactly what you want. So why do you want to do something different? You want the guy transparent, right?

Well the guy sleeping is transparent also because the top layer of video is opaque (empty couch over the sleeping guy). If I use a crop the line is noticeably different do to changing light. So what I have done is introduced a third layer of a matted video only the size of the guy sleeping that fades in.
See the sleeping guy becomes opaque then fades back, I just want to maintain the sleeping guy so that he never dissolves. The way I have it now will work, but why would a sleeping guy dissolve if the ghost walker was to rise out of his body…..until then I guess I will have to maintain correct lighting.
If I was only the editor and had to work with this footage only, which i do it seems an editor could work with this scenario. i am still rough to fcp controls so this is coming along slowly.

Actor SLEEPING on V1 = 100% opacity,
never change it.Actor WAKING and WALKING on V2 = find a good “mix” of between 40% to 80% opacity,
only change (ramp) the opacity when you bring the effect IN or take it OUT.That’s all there is to it, no matte needed as the V1 SLEEPING actor will always appear 100%.

It occurs to me that you may not have enough footage of the “sleeping” actor to give enough time for the WALKING away.
If this is the case:
You should create a FREEZE-FRAME of the actor in bed and leave that freeze on V1.
That will allow him to “WAKE UP and WALK away” on V2 (opacity lowered) while the freeze-frame on V1 remains 100%.This whole effect is only possible if the camera shot is LOCKED DOWN for entire duration of the mixed effect.
