If you do terminate it with a 75 ohm resistor, be sure to put it BEFORE the
DC block capacitor (that is, on the camera side of the cap). The LM1881
performs DC restoration as a part of its processing, and if you try to tie
its input to ground through a low impedance, I don't think it will be able
to restore properly.
