Advertising film or video (5)

I believe the answer is:

promo

I believe this is a double definition.

'advertising film' is the first definition.
(I've seen this in another clue)

'video' is the second definition.
(I've seen this before)

(Other definitions for promo that I've seen before include "advertisement" , "Ad" , "Advertising film/video" , "21 [TRAILER]" , "Advertising film or video" .)

I've seen this clue in The Times.
