How big would a 4 minute file be
 

I am writing a feature for a photographic magazine, can anyone tell me the file size of a 4 minute file captured on a 5D MkII ?

Thanks in anticipation

Roughly 1.2 GB.

Without looking, the 5D2 stops recording at the 4 gig mark, which typically happens around the 12-13 minute mark, so there you go...

(Ha! John and I simul-posted, lol.)

Thank you Jon and Bill, I appreciate you taking the time to reply.
