Where can I find information on how much data storage is used to produce a film? For example it took over 1 PB of data to produce Avatar.

I'm looking for a total number of data used after shooting and visual effects. Usually with cuts and edits studios can compress the film down to about 10-30 TB but thats not what I'm looking for. More interested in the amount of data that is produced in total from the making of one film. 

hence that "raw footage" wasn't the best choice of words!

Nikolay, how did you find that trivia fact from Dau? Trying to find other trivia similar to this one. 

Hi Catherine Boland,

I recommend that you check with your instructor to determine the scope of your research and what he or she considers primary sources of information. Many instructors do not consider IMDb a primary source.

Talk with you librarian for ideas on how to research this subject. If you are a college student, your college librarian probably has more resources to help you find this information than a high school librarian.

There are a number of professional trade publications for VFX. Here are a few that may be helpful.

Hi Catherine Boland,
As a follow-up: I'm a long time user of IMDb and have a background in computer science. After you turn in your research paper to your instructor and after he or she grades it, I would appreciate it if you make a copy of your paper available via a blog or other suitable means, and providing a link to your paper.

IMDb depends upon users like you to add information to their database. If you locate information pertinent to IMDb that IMDb doesn't already have, please consider adding that information.

Best of luck on your assignment.
