Hi,

I was wondering if anyone had done a bit-perfect rip of the isolated music and effects track from the 1989 MGM/UA LaserDisc of The Wizard of Oz. I would like the track to be a PCM WAV file so I can mux it to a rip of the 1999 DVD (which I own), and I would like the track to be sync-able to the rip. I don't have the 4K Blu-ray release, since I don't have anything UHD-related yet.

Thanks!

I want to find out if the japanese movie (not the remake) "Dark Water" (the Arrow release) has the original mix. I suspect it's a remix.

DTS Stereo is 5.1? I don't think so, and I think must be LPCM 2.0 stereo. Am I right?

I thought share my little personal project (and first ever) here.

As there are only rumors that a UHD version of this wonderful movie (in my opinion) should be released in the nearer future, i decided to make the wait bearable and take the bluray and an Open Matte Version of "Drive" - who doesn´t love more picture - and create a hybrid version (wih the tremendous help of spoRv), because not all have access to the famous meican OM bluray release.

Audio:

• DTS XLL 5.1 as flac (audacity couldn´t export it in .wav due to the 4Gb limit - the hell i know why would the dts track from the bluray become bigger afterwards)
  
• AC3 5.1 640 kb/s
  

I've lately been interested in how 5.1 home video audio mixes across various formats compare to their theatrical counterparts. So I've taken the cinema DTS tracks that I've been able to find or that others have kindly shared with me and done some visual waveform comparisons.

All cinema DTS tracks have had their surround channels attenuated to -3Db and LFE channel boosted +3Db for pre-1999 movies and +6Db for post-1999 movies. For more information on why this is necessary see this wonderfully informative thread by pipefan413.

So I'll start with The Matrix.


The Matrix - 1999 Theatrical DTS 6-Track



So here's the cinema DTS. It's a very dynamic mix with LFE and surrounds used fairly sparingly until the final 30 minutes of the movie.


The Matrix - 1999 DVD - AC-3 5.1 448kbps



The DVD release is not as dynamic as the theatrical DTS. Adjusted for volume the centre channel has a slight boost and LFE + surrounds have been toned down. It looks fairly close to the theatrical mix though.


The Matrix - 2008 Blu-ray - TrueHD 5.1 1646kbps



Once adjusted for volume this is essentially just a less dynamic rendering of the theatrical mix with LFE toned down a little. It's very close indeed. It could even be that these are near-field adjustments intended to recreate the sound of the theatrical DTS in a smaller space - I don't know enough about this to be able to say.


The Matrix - 2008 Blu-ray - AC-3 5.1 640kbps



I'm not even sure why this track is on the BD. The TrueHD has an AC-3 Core track for compatibility so this seems utterly redundant. This one is an even more neutered version of the DVD 5.1. The centre channel dynamics have been squashed even further and the LFE in the finale has been toned down yet again. Worse still, this is the default audio track on the disc so the vastly superior TrueHD track has to be manually selected.


The Matrix - 2018 Ultra HD Blu-ray - TrueHD 7.1 4868kbps



Unsurprisingly the Atmos track on the UHD is a total remix with lots of additional LFE and boosted surround effects. From an authenticity standpoint, it has no value whatsoever.


The Matrix - 2018 Ultra HD Blu-ray - AC-3 5.1 640kbps



Anyone hoping that the 5.1 track on the UHD was the original mix is going to be disappointed. It's just a 5.1 channel folddown of the Atmos remix with a boosted centre channel.


Missing Mixes
Not included in this comparison is the LaserDisc AC-3 simply because I don’t have it though I've heard it's the same as the DVD 5.1. If anybody has it and would care to share then I’ll gladly add it here.


Conclusion (TL;DR)
The BD TrueHD 5.1 looks to be a very respectful attempt to create a slightly more polite rendering of the theatrical audio track. Anyone who maligns the BD 5.1 for being nothing like what they heard in the cinema in 1999 either has very keen ears or went to the wrong cinema.

Would anyone happen to have the mono audio of Nightmare on Elm Street (1984) [I-5036], for a possible future project? Thanks so much!

Is it to compensate for the fact that the front 3 speakers are behind the screen? And if so, is the intention that the audience perceives the levels as the same?

If this is true then the accepted wisdom that cinema DTS rips need to have their surround channels attenuated by -3Db for home viewing would be wrong.

It's interesting when looking at home mixes that are close to their theatrical counterparts as some apply the attenuation and some don't.
