Smoke Cleaning mask feature request (Magic Box)

[chadi]

I have used this feature in other softwares.

You have a clean mask/key of a figure shot with in front of a chroma wall with trackers, you place your null/object/box inside the clean white mask, and it will remove all disconnected objects/spots/masks outside this mask.

May be it exists, may be not

Thanks Smokers

What software have you used it in?

[chadi]

I know you will not accept this as an answer, but I tried it in a in-house compositing software at BUF a VFX company in Paris.

They are supposed to release their softwares for the masses but it didn't happen yet.

But I am quite sure I used this function in another soft, but I am not sure may be (Nuke-Shake-AE...etc.)

Thanks

Is this what you're trying to do? See pic.

Add another mask inside of your Gmask.

Hi Sonstegard
I am not sure this is it, if I can read it well you try to make a custom mask to manually eliminate any other white areas outside.
The function I am searching is a null that you place inside a white spot that will automatically detect its boundary and ignore anything outside this boundary.
In photoshop imagine this as a magic wand that can detect only where you click.
Does it make sense?
Best regards

Yes, that makes sense.

But, I don't know of anyway of doing that in Smoke other than creating a mask and tracking it inside or outside of the key.

Sorry.
