Author Topic: DTS Stereo Steve Kraus Film God Posts: 4094 From: Chicago, IL, USA Registered: May 2000 posted 02-12-2002 09:10 PM                    (I refer to the SVA analog track not the discontinued 2:4 matrixed digital system.) In absence of other information do we presume SR or A? I run a tremendous variety of films and in my experience A is pretty rare; if it's stereo it's almost always SR. I encounter mono more than I do A. Can one make a presumption of SR about a print credited to DTS as well?  |  IP: Logged Richard Fowler Film God Posts: 2392 From: Ft. Lauderdale, FL, USA Registered: Jun 2001 posted 02-12-2002 10:56 PM                     DTS analog stereo track was a type A, but may have changed....Karen should know.

As Richard says DTS Stereo has always been A-type. I was told some time back by a DTS insider that this was because DTS didn't want to get involved with any legal shootout down at the Double-D corral (you know, patents an' all). However it IS very confusing because traditionally, if a film has both Dolby Digital AND DTS then the analog track will always be SR. But if it has only DTS then it should (in theory) always be A-type. The big question is - has this changed in recent times, particularly since DTS developed their SR emulation scheme for the DTS-6AD? As far as I know it has not, but if it has changed, then surely the logo should be also changed to "DTS Stereo SR"? How about it young Karen? ------------------ Ray Derrick President/Chief Engineer Panalogic Corporation Sydney, Australia Phone: 61 (0)2 9894 6655 Fax: 61 (0)2 9894 6935  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 02-13-2002 03:57 AM                     I'm a bit curious as to what the last dts only movie was. I have a feeling it's been at least a few years since an A track was produced, but a very interesting question nonetheless.

No SRD. I was assuming the analog tracks on these would be DTS Stereo. (and thus A type)  |  IP: Logged Jon Bartow Master Film Handler Posts: 287 From: Massachusetts Registered: Nov 1999 posted 02-13-2002 07:07 AM                     "Original Sin" was in DTS only without SRD. I don't remember a SDDS track but then again none of my theaters use the SDDS system so I don't usually look for it. As I remember when it was playing in a house without a DTS player it was in SR, and supposedly it sounded fine.  |  IP: Logged Jeffry L. Johnson Jedi Master Film Handler Posts: 809 From: Cleveland, Ohio, USA Registered: Apr 2000 posted 02-13-2002 12:04 PM                        In 1997 January I posted to rec.arts.movies.tech that, in response to my email query, Karen Hultgren said that DTS has used SR noise reduction for three years. "Universal almost always releases their movie's stereo optical tracks in SR." -- Patrick T.

Posts: 10973 From: Lawton, OK, USA Registered: Apr 2001 posted 02-13-2002 06:55 PM                     Actually, all Universal Studios movies still have their analog SVA tracks branded as "DTS Stereo", even though the DTS Stereo logo is rarely featured on their film credits anymore. The NY and LA area stack ads still use the icon. As to the A or SR thing, I guess it could go either way. I have some old THX TAP sheets where films like "Casper" were listed as having "DTS Stereo SR" type tracks and to play back those tracks using Dolby SR or SR compatible modes.  |  IP: Logged Bobby Henderson "Ask me about Trajan." Posts: 10973 From: Lawton, OK, USA Registered: Apr 2001 posted 02-13-2002 07:03 PM                     Oh, and on occaision some MGM movies will actually appear with only DTS Digital and DTS Stereo audio.  |  IP: Logged Karen Hultgren Master Film Handler Posts: 492 From: Agoura Hills, CA, USA Registered: Mar 2000 posted 02-13-2002 08:06 PM                        Hi Steve, Yes, here at DTS, we can do optical tracks in either A-Type of SR-Type. Both are compatible with Dolby A-Type and SR playback systems. Karen at DTS  |  IP: Logged Karen Hultgren Master Film Handler Posts: 492 From: Agoura Hills, CA, USA Registered: Mar 2000 posted 02-13-2002 08:09 PM                        Just a quick note, most optical tracks these days are done in SR. Very few release in A-Type. Whatever the studio wants, we do. And, DTS STEREO can be either A-Type or SR-Type. We can do both. Karen at DTS  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 02-13-2002 09:23 PM                     Is it not more of a question of what is on the mag printmaster you recieve to make the optical neg from rather than an encoder question to determin the final release?  |  IP: Logged Ray Derrick Master Film Handler Posts: 310 From: Sydney, Australia Registered: Sep 2001 posted 02-14-2002 05:55 AM                     So obviously the answer to Steve's question, at least with recent films, is "assume SR". But is there a definitive way to tell, other than a listening test? In other words, is "SR" always marked on the leader with a DTS-only SR print, Karen? ------------------ Ray Derrick President/Chief Engineer Panalogic Corporation Sydney, Australia Phone: 61 (0)2 9894 6655 Fax: 61 (0)2 9894 6935  |  IP: Logged
