I rendered a Tiff sequence in Maya using MRay and applied motionblur to the whole sequence.
the problem I had was that in some frames some parts of my rig are moving unexpectedly.
I tried rendering the single frames and something weird was happening
when rendering frame : 162 for example, the time slider moves to 162.2 and some parts of the rig move or rotate.
so I end up with these big pops on my animation.
