Drive off, cutting short filming (4)
I believe the answer is:
shoo
'drive off' is the definition.
(shooing is a kind of driving off)
'cutting short filming' is the wordplay.
'cutting short' means to remove the last letter.
'filming' becomes 'shoot' (as in a film shoot).
'shoot' with its final letter taken off is 'SHOO'.
(Other definitions for shoo that I've seen before include "Push off" , "Exclamation used to chase away animals" , "Go away quickly!" , "Drive away" , "Expression to chase away an animal" .)
