Film dive-bombing duck (5)
I believe the answer is:
video
'film' is the definition.
(I've seen this before)
'dive-bombing duck' is the wordplay.
'bombing' indicates an anagram.
'duck' becomes 'o' (resembles zero - 'duck' in cricket).
'dive' with letters rearranged gives 'vide'.
'vide'+'o'='VIDEO'
(Other definitions for video that I've seen before include "TV/film cassette" , "Transmitter of televised image" , "Relating to televised images" , "(Tape for) recorder of film etc" , "Visual element of television" .)
