Yes. Though I keep advocating the GPL's definition of "source", I
recognise the ambiguity of "preferred" in that definition.

Whatever form is preferred for making modifications to the work.

The closer we get to the original digital information, the less lossy
the representation, so that should be preferentially selected; but for
the reasons you give, I think each of these forms would reasonably
satisfy a need for "preferred form for making modifications".

So long as the software tools to render it are either freely available
elsewhere or included in the source, the work can at least be ported
to build on other hardware if necessary. I think this would be free.

I don't think this would present an issue for "preferred form of the
work for making modifications to it". It would limit the set of people
who *choose* to acquire such a large work.

Again, some people would prefer this, others would not.

I think the issues of different "preferred form" software formats for
a video work is qualitatively similar to the issues of different
languages for a program. The main difference is that some of these
forms are lossy representations of an upstream form, whereas
Turing-complete programming languages could conceivably each be
translated to any other.
