A motion picture's released using modern tech (15)

I believe the answer is:

computerisation

'using modern tech' is the definition.
(use of computers)

'a motion picture's released' is the wordplay.
'released' is an anagram indicator (letters released from their original order).
'a'+'motion'+'pictures'='amotionpictures'
'amotionpictures' is an anagram of 'COMPUTERISATION'.

I've seen this clue in The Times.
