Masking in deep can be a whole other can of worms, yes.
Basically every time you are dealing with transparency of some sort
things get a little more complicated as you need to be able to define
how each sample that contributes to the transparent pixel has to be
treated to deliver predictable results.
I haven't worked with deep for a while, so I might be talking crap, but
I'm sure other people like Colin can explain better.

Yes, it makes sense now that you point that out. Thanks for the
suggestion Frank, static cameras should work to solve this problem.
Is there a similar reason explaining why the DeepColorCorrect does not
have a mask input?

From what I remember, DeepTransform does not filter like you would
expect from a 2D tranform, as that would be a potentially crazy
amount of calculations (every single sample would have to be
filtered and there could be lots).
Hence this node should be used with care for things like
reformatting overscan renders or static repos.
Why don't you render all CG with the same (static) camera as the
deep, wih a bit of overscan, and match move the lot at the end?

Hello!
I am running into some issues with the DeepTransform node and was
wondering if anyone has experienced similar behavior.
Basically the situation is that we have some shots that are very
nearly lockoff shots, just with some subtle nodal camera
movement. In order to save on disk space we are attempting to
render a single frame of deep data and matchmove this to the
plate's movement before doing the deep holdout on our deep fx
elements.
To do this we are trying to use a DeepTransform, but we are
running into an issue where it looks like the holdout is jumping.
I believe this is being caused by the transform x and y values of
the DeepTransform rounding to the nearest pixel values.
Does the DeepTransform node support sub-pixel transform values?
Is this not possible? Forgive me if this is a dumb question, I
understand Deep conceptually, but I'm sure there are subtleties
that I am not aware of.
