The short clip shows Danny John-Jules (Cat) and Robert Llewellyn (Kryten) having a make-up test, including Llewellyn in his Kryten mask. It was released on TV channel Dave's official website.
A message on the site read: "It's really happening people. Red Dwarf X is in production for 2012 on Dave and to prove it here's an exclusive video of a couple of the boys in make-up."
Red Dwarf is currently shooting its latest series at Shepperton Studios in front of a live audience, with an airdate expected to be late 2012 on Dave.
Craig Charles, Chris Barrie, John-Jules and Llewellyn will return for the cult sci-fi's first full series since 1999.
