The cinema DTS track for Titanic is also the same set of discs used in 70mm presentation.

It is absolutely reference. It has so much dynamic range and can play so loud without hurting. It's one of the best mixes in cinema history. The home ones are all fine to my ears but there is something a little extra magical about the CDTS.

I heard it did also had a "DTS Special Venue" 8-track mix with the 70mm showings (not sure if it was the same as the SDDS 8-channel mix, though).
But, compared to the Atmos track, or even the DTS-ES 6.1 Discrete mix on the old 3-disc Special Collector's Edition (which, at the time, was immersive enough with the addition of the back Center channel ONLY for wind, ambience, and music cues) the Cinema DTS sound way more "in-your-face" and less compressed than any home video releases.

Also everyone should keep in mind that if you extract and create the LFE manually yourself rather than let the plugin for Foobar do it for you, which is something that is probably best, to do it yourself[...]

Something which - apparently - doesn't seem to work reliably anyway, depending on the version of the plugin. 🙄

[...]you do NOT ad +6dB to the LFE. You actually do a -3dB for pre-1999 discs and just leave as is for 1999+ discs. Surrounds do get -3dB.

Or, to be more precise, under the premise that the LFE level shall remain unchanged, you mean for pre-1999 discs:

L,R,C (-3dB)
LFE (0dB)
SL,SR (-6dB)


and for 1999 and later discs:

L,R,C (-6dB)
LFE (0dB)
SL,SR (-9dB)

In order to prevent any (additional) clipping whatsoever, correct? Or, if the remaining headroom allows for it, raising the LFE to (almost) 0dBFS and attenuate the rest less accordingly.

It is absolutely reference. It has so much dynamic range and can play so loud without hurting. It's one of the best mixes in cinema history. 

Just in case you don't have it yet - there's also a 5.1 version of the soundtrack/score as a DTS-CD which I can recommend.

Movie: The Fast and the Furious (2001)
Source: Cinema DTS
Input: 24 FPS AUD
Output: 23.976 FPS FLAC
Synced To: UHD

Thanks to @david49120 for sending me the raw files to sync.

IMDB lists a couple soundtrack changes between the original theatrical version and the DVD, but I checked the listed scenes and the soundtrack is the same between this and the R1 DVD.

Movie: The World is Not Enough (1999)
Source: Cinema DTS
Input: 24 FPS AUD
Output: 23.976 FPS 6.1 DTS-HD MA
Synced To: 4k web-dl (deflate) / xebec with -459ms delay

Special thanks to @david49120 for sending me the raw files.

This is synced to Deflate, would you know how much delay to apply to the more recent Xebec version?

Didn't realize there was a more recent web-dl. Is it the same master? Is it a significant upgrade?

[Stamper]

Yeah it’s more detailed. I will calculate the delay for anyone interested. Hopefully it syncs all the way through!

Addition: so I did have problems with the deflate as it's a 16/9 captured file and it as some weird coding that prevent it from importing in fcpx. The Deflate is 11 frames ahead of the Xebec, so you need to apply a delay of -459ms. I'm not sure if we need to add the old -21ms delay or not (about custom DTS-HD files)?

The -21ms delay is already baked in to the mka, so you don't have to worry about that.

[Stamper]

OK hopefully I'm right with the calculation, 1000ms/23,976fps=41,71ms -> 41,71ms x 11frames = 458,81ms -> -459ms delay.

Edit, so it works if I add +459ms to your file. I'm confused LOL
