[Retired] The Dark Knight (Regrade and Imax Restoration)

Out of curiosity, may I ask what "Cinema DTS" means precisely?

Its a rip of the original DTS discs that we're sent out to cinemas during the theatrical run of the film.

They can be different mixes at times from the Home Video versions.
In the case of The Dark Knight there is very little difference.

Interesting. Do you know what exact format Cinema DTS is technically? Is it like DTS-HD MA? That is, lossless?

Compared to DTS-HD Master it's definitely lossy, but that doesn't mean it's bad either.

Cinema DTS is 4:1 compressed APT-X100:

Im unsure of the exact bitrate but it's around the 750 kbit/s mark. Im sure somebody else here can give us an exact answer.

I do know its way below what the Home Video version of the codec was able to be encoded at.

Another thing to note is im pretty sure the LFE channel is contained in the surround channels. It's extracted via a frequency crossover method in realtime and sent to the subwoofer.

Hmm, that's pretty unimpressive. Somehow I can't imagine cinemas use such a low quality codec when they can afford digital 2K projectors. Is it a kind of "fallback" solution or is that really the creme-de-la-creme?

P.S. Thanks for the infos.

Since the advent of Digital projection an uncompressed Audio track is included in the DCP.

The DTS cinema disc's we are talking about are old technology from the 35mm film print era and I believe started with Jurassic Park in 92. Im unsure of the last release to have this option.
35mm release contained a 2 channel analogue track and a Multichannel Digital Track (both using Dolby Technology's.) on the actual physical print. The DTS option was on a separate disc that would be synced to the print during play out.
The Dolby Digital option on the print had a lower bitrate than the DTS discs, and the DTS mix were often alot more dynamic making the DTS a better option.

I'm no expert and there are others here who know a hell of alot more than me. There are plenty of threads on this site that cover this so it's just a case of having a hunt around.

The compression is really a bit of a non issue. These discs can pack alot of punch.
if you get a chance to listen to the Jurassic park DTS cinema mix I highly recommend it

It's all in the mix. Which is why I'm having an absolute blast listening to laserdiscs again!

I love these thread derailments. Filmtech forum is a great source of information about the cinema formats, with posts from seasoned professionals. Anyone interested in this stuff should check it out.

Regarding the comment about 2k digital projectors, the big rollout came about when the studios/distributors got together and basically supplied the theatre chains with digital projectors. It was all about the encryption and doing away with physical prints.
