Compensate for not filming (6)

I believe the answer is:

offset

I'm a little stuck... Click here to teach me more about this clue!

'compensate for' is the definition.
(I've seen this in another clue)

I cannot understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for offset that I've seen before include "Counteract to compensate" , "Compensation; printing technique" , "Counterbalance or compensate for" , "Something that compensates" , "Distance out of line" .)

I've seen this clue in The Guardian.
