Wood taking minutes instead of seconds in film studios (3,4)

I believe the answer is:

elm tree

'wood' is the definition.
(type of tree)

I don't understand the remainder of the clue.

(Other definitions for elm tree that I've seen before include "Victim of a "Dutch" disease" , "plant" .)

I've seen this clue in The Guardian.
