Pay for mature clip from film (7)
I believe the answer is:
footage
'film' is the definition.
(I know that footage is a type of film)
'pay for mature clip from' is the wordplay.
'pay for' becomes 'foot' (as in to foot the bill).
'mature' becomes 'age' (synonyms).
'clip' means to remove the last letter (I've seen 'clipped' mean this (the word is shortened or clipped)).
'from' becomes 'e' (I've seen this in other clues).
'age' with its final letter taken away is 'ag'.
'foot'+'ag'+'e'='FOOTAGE'
(Other definitions for footage that I've seen before include "Length of film" , "Quantity of film (of event)" , "quantity shot" , "Piece of filmed material" , "Part of film" .)
