That is totally wrong. Being in Professional cinema business
for more than 16 years I can tell you that that statement
is so not correct. Getting down to basics.

35mm film negative has a far superior resolution than
any 2k or 4K production. 2K production is what Blue Ray
DVD is now offering. Standard DVD was offering a resolution
which was about an 8th or even a tenths of what the original
film negative was being produced. Blue Ray titles, take
the original film negative and downcovert it to 2K resolution
which is what Blue Ray offers and what actually todays'
D-Cinema is offering. The statement that original DVD
titles are upconverted to Blue Ray is totally wrong. The
standard DVD resolution can not have the definition seen
in the Blue Ray titles. Tell you what. Take a composite
signal and upconvert it to Component. What would be the
difference? Nothing. So taking a standard DVD and convert
it to Blue Ray there will be no difference so what is
the point of actually making this new High-Def format
anyway.

Films today are either being filmed on 35mm and usually
using 2K Digital technology to incorporate CGI effects
e.t.c. All Digital Animation is 2K resolution. 4K is in
the making steps for it to appear in professional cinema
but I doubt we will seen it anytime soon in Home Theater
applications. In any case, most producers who shoot Digitaly
their films are filming in 2K resolution so either watching
them in Digital Cinemas or standard theaters with 35mm
projectors will not see a difference.
