French artist composed a video feature (5)
I believe the answer is:
david
'french artist' is the definition.
(I know that David is a painter)
'composed a video feature' is the wordplay.
'feature' says the answer is hidden in the clue (I've seen 'featuring' mean this).
'DAVID' can be found hidden inside 'composed a video'.
(Other definitions for david that I've seen before include "Welsh saint - French painter" , "Michelangelo statue" , "Goliath's slayer" , "singer/harpist?" , "Hebrew king" .)
