You assume correctly.

:With reference to the comment about "licensed product", in the interview
:with the president of Nuoptix Inc., he explained that their company
:also developed a new "film-to-tape process" by which they can get
: 60+ frames per second rather than the standard 24 fps. This explains

:3-D effect because the eye receives more (faster rate) information, more
:like real-life. This is *probably* what they license(?).

Video is 30 frames per second, and 60 fields per second.  A complete frame
is composed of two fields, each of which has alternate scan lines.  So it's
like you see the odd lines, then the even lines, each frame.  Sound film
is 24 frames per second.  Film-to-tape transfers do what is called a
"3:2 pulldown" to correct for the difference in frame rates.  There is
nothing special about this, either.  The reason the commercial looked
so "crisp" was that it was shot and produced on video -- and very good
video at that.  That means that there were no motion artifacts from a
film-to-tape transfer to worry about.  Anyway, other than just staying
pure video there's nothing they can do to get information to you at a
faster rate.  (On the other hand, ShowScan, a film process, *can* do that.
And it's a lot better than 3-D.)
