Interop was never a real standard, it was a really smart move from DCI
to get all the pieces of the chain interopeable while SMPTE finished
writing the actual standard. That's my vision on the formal side of
it.
Interop works for what majors call a movie, that's Flat or Scope, 24
fps, 5.1, multireel, no subtitles. Anything else you are gambling in
how the projection system will deal with it.
I won't even start with the little Interop monsters like 25fps or
SMPTE-XML subtitles.
SMPTE DCPs are all over the place on commercial cinemas: HFR releases,
some 3D notably from Disney, and hundreds of smaller advertisement and
whatelse.
Wide releases from majors in the thousands of copies still try to
avoid the odd and the known problems some really outdated theaters may
have. This kind of release have already hundreds of problems to deal
with that are not related to the chosen standard.
When majors will move to SMPTE I'm looking for theaters to go and get
some automation improvements. Personally, I'm waiting for projection
format chosen based on CPL metadata, and TKR.
Software server updates with SMPTE support have been available for
years. I don't feel sorry anymore for a theater that doesn't maintain
their equipement, and software updates are a really cheap part of
keeping your machines working and ready.
I have never released an Interop DCP
I have never had a problem with any DoM created SMPTE DCP (but I don't
do that many wide distributed DCPs to be honest)
I have yet to know a theater that can only play Interop
I hope the default standard can be predefined in the preferences, that
will save many people the extra click. I hope this change doesn't mean
SMPTE features will be forgotten in the future of DoM.
We do festivals and subtitles and slideshows and many other things
that are not a movie for a major. I firmly believe that SMPTE gives
DoM more and better options to make its magic happen.

OK, interesting! I'm about to embark on
making all the DCPs for 3 UK festivals. Have always used SMPTE in the past and found it
rock solid, so nervous about switching, but it sounds like Interop is a better choice.
Can anyone vouch for DCP-o-matic's stability and correctness when creating Interop
DCPs on OS X (Yosemite)?
I haven't seen real issues for INTEROP vs. SMPTE, so, if you have a proven workflow,
I don't really see a reason to switch. It's not that SMPTE is broken. It's
more of a formal issue. After all, the cinema industry is struggling for years to move to
SMPTE, so, I am not surprised we see some issues in the DOM community as well.
It's just that I wouldn't follow the recommendation to always create SMPTE
because 'it's the new format and INTEROP is outdated'.
Maybe also some misunderstanding came up because of the former 'MPEG2-Interop'
DCPs. Some people somehow seem to have shortened this to 'INTEROP'. However,
MPEG2-Interop REALLY is deprecated. But NOT J2K-Interop.
Give 2.9 a try. It has lot's of interesting features, I haven't experienced the
Mac versions to be exceptionally unstable. There may always be a glitch or so with a new
test version, but in general, these are only up for a few days before Carl fixes them.
