Mask Effect to make person disappear
Hi,
I am trying to make a person disappear from a shot as if they have turned into pixels and then exploded and faded away.
The shot is a crane shot, so there is some motion, and the person that I want to disappear is also moving.I have not used Apple Motion before, only Final Cut Pro, so I am completely new to using a third party effects app along side FCP, therefore I know little to nothing about how to use the software.
There is another shot I want to do something similar in, however in this shot, the person is supposed to appear and piece together pixel by pixel, as if the pixels from the first shot have dispersed, and then recollected in another location to reform the same person.
The complication in this shot is that there are people in the forground and backgroud, some of them are in front of the person I want to make appear.If you have any tips on how I can achieve these effects, I would be very grateful. Keep in mind I am new to Motion.
Thank you. -

Let’s see the shots- otherwise it’s hard to recommend a solution.

Check out some of Andrew Kramer’s tutorials on VideoCopilot.net. Though his tutorials are for After Effects, the concepts will still apply.
From your description, it sounds like you’re dealing with the absolute worst-case scenario: a moving subject, a moving camera and moving background objects. You’ll most likely have to rotoscope your subject by hand, a task that will be VERY daunting due to interframe motion blur. And even if you can cut a clean mask, you’ll have to figure out what you’ll put in the “hole” he leaves when you mask him out.
Just so you know (in case you’re asked to do this again in the future), this scene should have been shot in two different takes. The first would have been a shot of everything BUT your disappearing man.
The second shot would have been of ONLY your disappearing man, shot against green-screen, with the camera moves matched exactly to the previous shot.

I’m assuming that you shot this with motion control, and there’s a 2nd take with a clean plate.
In which case, you’d rotoscope the person out of the background, apply the pixel explosion and lay it over the clean plate.

Oh riiiight- I’m sure that’s what he’s got. 🙂

Thanks for your help everyone.
I do not have any of that. I have not shot anything twice, there is no blue screen. All thats there are the two shots of the person I want to make disappear in one shot, and then reappear in the other.
While the tutorials you directed me to were very interesting, they had all those elements that I am missing.
How can I send you the clips so that you can take a look?
I realize that what I’m trying to do is near impossible and very time consuming as I have not gone about this in the correct way, however anything you can suggest that would make this look half decent would be greatly appreciated.
Thanks for all your help.

But make it into a very small H.264 at quarter res first- otherwise it will take forever.

Well, that’s a problem. You have to have something to replace the person with. You might be able to clone background in from other shots, but it’s a lot of work and may not be all that clean.

Way to swing for the fences on your first Motion project… 🙂
I just hope you don’t get frustrated with Motion trying to pull of this incredibly difficult FX shot (difficult because there was apparently no pre-production thought put into it).
My advice is to temper your expectations. With what you describe, even an experienced Motion or AE user might not be able to pull it off convincingly.
If I was given this shot, I would probably want shake or combustion or nuke to pull this off, not Motion.

Thanks for all your help and suggestions everyone. I realized that what I was attempting to do is far too difficult for someone with my level of competence with 3rd party effects editing apps to accomplish, so I have given up on those ambitions, and kept things simple.
Thank you once again for all your help.
