From an audio standpoint, Jurassic Park is my favourite movie. So I went searching for as much information as I could about how this audio mix has been treated over the years. A lot of what I found was conflicting, unsubstantiated, or just plain incorrect. So I got together the audio tracks from every release that was available to me and set about comparing waveforms. This is what I found for the benefit of anyone interested.


Jurassic Park 1993 35mm 1080p Cinema DTS v2.0 - DTS-HD MA 5.1



Let's start with the original Cinema DTS track from the 35mm v2.0 release. You would think, having been sourced from the original DTS CD-ROMs, that this would be the final word in theatrical accuracy. But you’d be wrong.

First of all the surround channels are too loud. Due to the way cinema sound systems are calibrated compared to home systems, any theatrical DTS track intended to be played at home theatre levels needs to have its surround channels lowered by -3dB. It should be noted that the standalone DTSHD release of the Cinema DTS track already has the surrounds attenuated but (the one on MySpleen at least) has a completely empty LFE channel.

The second problem is that the LFE channel is not loud enough. According to schorman who compared the output of various DTS decoder plugins with actual DTS hardware, movies pre-1999 need the surround channels upped by +3dB.

So by applying these two changes we should get a Cinema DTS track that we can assume is accurate to theatrical levels. I'll call this Theatrical DTS (Corrected) and this will be the mix that all others are compared to.


Theatrical DTS (Corrected)



There is one possible problem with this mix in that there are more sounds present in the LFE channel than in any of the home video mixes. This could be because the theatrical DTS simply was this way or it could be due to incorrect decoding of the matrixed LFE channel from the surrounds. In his comparison of DTS decoders schorman noted that different software plugins (even different versions of the same plugin) produced different results in separating the surround and LFE channels. So without knowing exactly what software and method was used to decode this track we can't know for sure that the resulting channels contain the correct information. My personal view is that, since DTS themselves handled the decoding for the home video mixes, then those are likely correct and something is slightly amiss with this one.


1997 DTS LaserDisc – DTS 5.1 1411kbps



The LD DTS is the most divisive home video mix. Some rank it amongst the greatest LD mixes ever produced whereas others call it overcooked with unattenuated surrounds and crazy LFE. Compared to Theatrical DTS (Corrected) the surround channels indeed have not had the required -3dB reduction applied. It’s also true that the LFE channel is much louder resulting in an overpowering mix. In all other respects, this track is practically the same as the theatrical DTS.


2000 DTS DVD (1st release) – DTS 5.1 768kbps



The first DTS DVD release is widely considered to be a defective disc with claims that it had a severely neutered LFE channel or no LFE channel at all. But this is untrue. The LFE channel is there and actually has a slight boost compared to Theatrical DTS (Corrected). The surrounds are also correctly attenuated. The big problem is that the centre channel is too loud to the point of clipping. Perhaps this was an attempt at a near-field mix. Overall though I would say this track is far from defective and is actually a lot closer to the theatrical mix than the AC-3 DVD to which it is frequently compared.


2000 DVD – AC-3 5.1 448kbps



This one was a surprise particularly given that, whenever I’ve seen it compared to the first DTS DVD, this is invariably held as the superior track. In fact, this is a total remix bearing very little resemblance to the theatrical mix. Maybe the reason people thought this sounded better is that many of the LFE effects are way too loud. Also, the left and right channels are mixed a lot lower relative to the others. Comparing this to the first DTS DVD is like comparing apples and oranges which makes it surprising that a second DTS disc was ever issued.


2000 DTS DVD (2nd release) – DTS 5.1 768kbps



The second DTS DVD’s mix is essentially the exact same mix as the LaserDisc but with surrounds correctly attenuated this time. I guess the studio figured that since everybody enjoyed the overcooked LFE of the LaserDisc they would just throw that onto the disc, fix the surrounds and call it a day.


Chinese Region 6 DTS DVD – DTS 5.1 768kbps



The Chinese R6 DVD has a unique DTS mix compared to all other home releases and it’s extremely close to Theatrical DTS (Corrected) with all the relative channel levels looking right. The LFE channel has not been boosted and the surrounds are correctly attenuated. In fact I would say that this appears to be a genuine effort to release the original unaltered audio mix.

It doesn’t have the additional LFE information that the Cinema DTS track has but whether that makes it more or less theatrically accurate is a matter for debate.

The one and only problem with this mix is that it’s from a PAL release and hence needs correcting to play at the correct speed and pitch. Also it's also wrongly reported on the net as being full bitrate DTS but it’s 768kbps just like the other DVDs.


2011 Blu-ray – DTS-HD 7.1



The 7.1 track on the BD release is another complete remix with some added and altered sound effects to boot. It is certainly not, as is reported elsewhere, the theatrical mix with the surrounds split. I almost wasn’t going to include it in this comparison since if the goal is theatrical accuracy then it’s of no use whatsoever.


2013 3D Blu-ray – DTS-HR 7.1



Finally we have the 7.1 track on the 3D BD release. This based on the BD 7.1 with the same altered effects but is perhaps of some historical interest since it did play in cinemas making it a theatrical mix and it was also overseen by original sound designer Gary Rydstrom. In practice it’s just a slightly more refined version of the previous 7.1 mix.


Missing Mixes
Not included in this comparison are the following tracks simply because I don’t have them:

LD AC-3
R2 Superbit DVD

If anybody has these tracks and would care to share then I’ll gladly add them here.


Conclusion (TL;DR)

There is not yet any release of Jurassic Park that has theatrically accurate audio out-of-the-box. The 35mm v2.0 DTS needs the surround and LFE levels adjusted and the LFE content is arguable. The LD DTS needs surround and LFE reductions. The R6 DVD has all the correct channel levels but must be PAL corrected. Any of these adjusted tracks should get you very close to the original 1993 DTS mix.

Hello all,
Could someone please extract the audio from the Teaser of Mission: Impossible (1996), from either the UHD BD or the 25th Anniversary Edition BD?

I'm working on an audio preservation project of Mission: Impossible music, and would love to include this bit  

Thanks!

Hello.

So I do Anime Series Movie Recuts (among all other my pasttimes), meaning that I take an anime series, I remove everything unacessary and keep anything that is integral to the plot.

I also remove any shot that is just padding (even the sneaky 1-5 seconds shots that just dither time) and make it so that the experience is a s flowing as possible (may vary in relation to the type of anime, animes with stand alone episodes like Samurai Champloo are the most difficult to work on).

This is the list of "Movie Recuts" available.

Just search for "anime movie recut youtube playlist" on google and you will find what you need (a Youtube Playlist)
List is updated regularly each forthnight.

In case you have "Emule", just search for "recut" and you will find my files

Star Trek 2 The Wrath of Khan Theatrical Cut (Sky HDTV 1080p v1.0)

I know the UHD is coming out very, very soon but my favorite rendition of the ST2 has always been the Sky version (also previously on iTunes). I love its warm, saturated look and very film like appearance. And my favorite cut of the movie is the theatrical cut (TC) even though the DC isn't bad (unlike ST6). So I went about cutting the Sky broadcast into the TC and added the 2 or 3 shots missing from one of the BDs. Although I like the HDTV it has a host of problems common to broadcasts. First the black levels are off and second there is a ton of macroblocking, some minor others major. I set the correct levels for the movie and then upscaled the movie to 4K and ran marcoblocking filter to fix 95% of the problems. For the remaining 5% of issues, half I went frame-by-frame painting out the macroblocking. For the parts left that couldn't be fixed with any methods, like so:



I plugged in parts from other TC BDs and color corrected them to match. Shots from the final battle with static on the viewscreen I left alone as the replacement's color didn't work. The end results were downscaled back to a 1080p MKV.

For audio I included the older 1st gen BD's tracks, the wonderful PCM from the laserdisc and finally the tracks from the first gen TC DVD. The DD 2.0 on the DVD sounds surprisingly really good.

Video:
The Sky HDTV broadcast with the correct levels, macroblocking cleaned up and frames replaced if need be, cut down to the TC.

Audio:
1. PCM 2.0 Dolby Surround (from the WS laserdisc)
2. Dolby Digital 2.0 (from the 1st Gen TC DVD)
3. Dolby Digital 5.1 (from the 1st Gen TC DVD)
4. Dolby Digital TrueHD 7.1 (from the 1st Gen TC BD)

Playtime (1967) Studiocanal BD synced to Criterion BD

Best sound!

"The Criterion 3.0 has been hit by some moderate noise reduction (and for no real reason – there was hardly any hiss anyway), while the StudioCanal has more high frequency detail and therefore possesses greater clarity."
