Hi Ivan,
that is interesting with the motionblur.
In my experience sofar, when getting cameras into nuke via exrs it was
always best to use the matrix on the camera instead of converting all
back to euler values in the rotation knobs ?!
It was more accurate and motionblur issues were gone ?
I know that is not exactly what you stated but I would be interested if
you expierenced the same thing with the cam data from exrs?
cheers

Might be splitting hairs, but since this comes up every now and then,
I think it's worth noting that there are some important caveats to
using the local_matrix knob to do that for animated cameras:
- You lose the ability to tweak the animation afterwards.
- Inaccurate motionblur. If you bake animated transform knobs into a
single animated matrix, you're effectively losing the ability to
interpolate "curved" paths correctly. The matrix values will
interpolate between frames, but there's no guarantee that the result
of that interpolation will match the transformation you'd get by
interpolating the original rotation/translation/scale values.
Getting back to the use case of the original post, I would recommend
keeping the two separate transforms when exporting out to Maya.
For one, if you use the "forced local matrix" approach you'll have no
easy way to transfer that to Maya (as in, it won't export correctly
when writing an FBX file, for example).
But also, if you're planning to refine animation later on, it might be
easier to do so on the original transformations.

Stoked, solved it. Very easy thanks to the exposed World and
Local Matrix's.
Attached is a verbose tutorial nuke script; all instructions
included in stickies. Hit me up if it needs more work. thanks!

I just retested my test and it only worked on simple setups.
Probably need expert equations to make it work properly!

I guess now would be a good time to learn expressions.
I'll check that out, thanks!
