vcs for hefty video and graphics files

I hope not to appear to be sneaking in a war of systems, and may rate a bit a high in windbag factor since I've asked a very similar question here but quite a while ago

I'd like to briefly describe my projected usage of a versioning system and see what people here think in terms what system best suits to that usage.

I'm a light weight semi-professional videographer but I have enough going on to feel a need to keep track of and be able to rollback versions of a project as it is being worked on

It would involve on any one projects something like 15 to 60 GB of stuff to keep up with. Large numbers of images and a dozen or 2 dozen video files. All in some stake of compression depending on the codex.

I'd like to keep a few version of say an Adobe Premier project with all the attendant files that play a role in it.

Ditto for sets of Adobe After effects and attendant files. And many many images and compilation in various states of cutting or whatever editing.

And then the whole project including the various Premier and After effects sets and piles of captured video tape. All in DV-avi format.

So versions inside versions and then repeated for different projects.

Each of which may have more than 1 version.

But cutting to the chase... assorted video and graphics files amounting to between 15 - 60 GB in any one project

Each project would only run a month or 2 months at the most and then all but the final delivered version would be deleted. That version might be keep for a yr or so.

I have some experience with cvs over quite a few yrs but still only a homeboy user and not very skilled or knowledgeable about cvs and even less with mercurial or git, where I do have some tiny bit of experience too.

Which of the main contenders: cvs subversion mercurial git bizarre Maybe a few more I don't know about, would be the best candidate for the usage and user described
