Maximum Quicktime Size?

I'll be using PRO V4.0 and 2 DL1s.

We have someone creating some Quicktime movies for the show.
Max length of any given one will be about 4 minutes.

What are my limitations for the file size of the Movie?

My initial guess would be the drive free space, but I don't want to run into a Catalyst limitation.
