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.
