[MacDV] To Demux or Not To Demux That Is The Question

[Mark M. Florida]

I would guess the reason "demuxing" was not covered in these books, is that
generally it is not relevant in the realm of capturing and editing video
with iMovie, QuickTime, Premiere, FCP, etc.  It only becomes relevant when
you need to re-edit footage that has already been compressed into the final
delivery format of MPEG (which was never meant to be an editing format).

In the past few years MPEG technology has picked up a lot of momentum, and
maybe demuxing MPEG files for re-editing is more relevant now than possibly
when the books were written.

Just a few thoughts.

BTW, you know the people on this list are *always* here to help out when it
really matters.
