The OKD does require modifiable form, and I could definitely see
spelling out what that means for film.

What do you mean by FCW being too demanding on the "free" part?  It
makes the same demands as the OKD.

You're right.

The distinction exists but is a lot fuzzier and degraded forms remain
useful for modification, just somewhat less useful, unlike software
where object code is tremendously less useful than source.

I often put a few slides on this in presentations eg
http://www.slideshare.net/mlinksva/how-far-behind-free-software-is-free-culture-presentation
but need to (am) write it up more thoroughly.

On that note, here's a fun one that I just heard about

You couldn't call it a CC license and doing so would be pretty dumb as
your modified scheme would be incompatible.

Or as Rob Myers just said, it would be a logistically difficult
requirement to introduce.  It wouldn't be impossible with cooperation
of  the license creator, perhaps analogous to the AGPL in terms of
creating new requirements while maintaining some compatibility with
the existing mass of copylefted stuff in the domain.

However, copyright enforcement (ie licenses) isn't the only thing in
life.  If "open source movie" can be made to mean something (certainly
uphill), or for that matter FCW/OKD gaining a strong brand that
reusers avoid the lack of, that's a vector. Probably even more
important are creation and publishing tools that make is easy to share
source (another analogy with software services ecology).

archive.org doesn't require any license at all, they just recommend
choosing one, and don't recommend one over another.
http://www.archive.org/about/faqs.php#223  I'll recommend to someone
there that they recommend choosing a FCW/OKD compliant license.
