I work for a Science research laboratory and we have to make an educational film blending animation and live video so here is the task:

Start off with a shot of a member of the audience-> then zoom into their arm-> then fade into an animation of inside their body.

The question is what camera to get that provides a decent zoom + high resolution (HD if poss) and still be able to stream it to a PC to be output on a projector. Any ideas?

(I have looked at the HDR-HC7E and HDR-UX7E).
