Yes. Possible.

The ST has one built in, one nobody seems to know about.

You can configure the SHIFTER Chip to take the HSync and VSync lines as
an input rather than output (external syncronisation).
If your VCR provides the synchron signals (possibly with an EURO
AV/SCART connector) just feed them into your ST, switch to external sync
and look at the picture on the monitor: it is a superposition.

I did this (for fun) with the pictures of two STs: resolution of 640*200
by 512*512 colors! Wonderful (almost Amiga)!
