try after effects (don't know how to use boris)
are the globe and the starfield already mxed together into one movie when
you put it into after effects? or can you bring them in separately as
separate layers and do the luma key in after effects? the second makes it
easier, but if they are together then you'll need to make a mask that moves
exactly over your globe. i'll assume that's what you're going to do.
now put motion onto one of your images so that it comes out of the globe and
floats around how you want it too. don't worry about the fact that it comes
out from on top of the globe. once you've got the motion right, select the
image layer, put the time marker in the composition window over a frame
which is after the image comes out from behind the globe, but before it goes
back over it. now choose "split clip" from (i think) the layer menu or the
edit menu. the layer will divide into two layers, the first of which you
should move so that it is behind your globe (or mask) and the second of
which goes over it.
hope that makes sense, if it doesn't i'll give it another go, but don't
worry, it's definitely possible to do it.
