Author Topic: CDS-Equipped Theatres Tim Reed Better Projection Pays Posts: 5246 From: Northampton, PA Registered: Sep 1999 posted 08-04-2003 05:19 PM                       Metropolis was the first soundtrack recorded digitally. Release prints were optical. What happened with CDS was that ORC touched it.  |  IP: Logged Stephen Furley Film God Posts: 3059 From: Coulsdon, Croydon, England Registered: May 2002 posted 08-04-2003 05:20 PM                     I regret never having heard CDS, I've managed to experience most of the others, Fantasound being the other major one I've not heard. I doubt that I'll ever get to hear either of them now. Anyone have a complete Fantasound setup, and print tucked away at home somewhere? There are some photos in the Widescreen Museum, and it's amasing, something like nine full-height racks, plus the spekers, and the two 'film phonographs', a strange term for them. Peter, I've mastered that ***** acop! In the past I've killed it by taking the relay out of the control box, it's marked 'this one', so it looks like smeone else has done the same in the past. On Friday, I arrived just over half an hour before the show, so I laced up the trailers reel, and gave it a go. Three times I failed to start the machine without the thing tripping, but the fourth time I managed it. With polyester, most films will fit on two spools, so there are only three starts per show, trailers, first half of feature, and changeover. Having it trip on either of the first two wouldn't matter too much, the audience would only notice a few seconds delay, but for it to trip on the changeover, would be a disaster. Both the trailer and feature starts were ok, so I decided to leave the acop active. I was feelng very nervous, coming up to the changeover, but it went through fine, and now I've done it a few times seems quite simple to get right. It's still a horribly designed system though, and if it were my cinema, it would be changed. It's just far too easy to trip the thing when starting. I've seen plenty of films there, without problems, so the normal projectionists have obviously mastered it long ago!  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 08-04-2003 05:23 PM                     Here are a couple of quick shots of the track on 70mm...  |  IP: Logged Bobby Henderson "Ask me about Trajan." Posts: 10973 From: Lawton, OK, USA Registered: Apr 2001 posted 08-04-2003 06:41 PM                     According to the print inventory list on the "T2: Ultimate Edition" DVD, only six 70mm CDS prints were made of "T2". Perhaps that's just the North American total. I'd like to what the actual data compression ratio comes out to for the CDS delta modulation process. I can't remember where I read it having a 4:1 ratio (I think that came from an article in "The Perfect Vision"). But that just seems all wrong. With close to 6 million bits of data running per second, that's really more than one would need for a fully uncompressed LPCM 6.0 track. You could probably even do 8.0 LPCM at that rate. It would seem like a lot of the data in that stream was there for error correction, which would have big a big deal considering the state of technology back then. I've seen only four movies in CDS, but never heard it drop out to silence.  |  IP: Logged Tim Reed Better Projection Pays Posts: 5246 From: Northampton, PA Registered: Sep 1999 posted 08-05-2003 10:47 AM                       CORRECTION: I have it on good authority that the 1982 release of Fantasia was the first soundtrack recorded digitally. Metropolis was 1984, and had some digital sound screenings using an interlocked playback unit.  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 08-05-2003 11:02 AM                        The digital sound version of Metropolis (Glen Glenn sound, Giorgio Moroder) premiered on December 6, 1984, using the sound system at the Century Plaza Theatre in Los Angeles.

Besides Brad's answer, they also had THX Broadway in 70MM with a CDS track. They also stuck trailers with the CDS soundtrack on it. I have a 70MM CDS Broadway and a 35mm trailer for "Sleeping with the Enemy". Just like the regular THX logos at the end it has a CDS logo in the corner of the frame. I also have afew sound loops for to.  |  IP: Logged Carl Martin Phenomenal Film Handler Posts: 1424 From: Oakland, CA, USA Registered: Feb 2002 posted 08-05-2003 01:40 PM                        did the cds track have an offset, and if so how many frames? carl  |  IP: Logged Tim Reed Better Projection Pays Posts: 5246 From: Northampton, PA Registered: Sep 1999 posted 08-05-2003 02:36 PM                       quote: Fantasia opened at the Century Plaza with double-system digital sound on February 8, 1985, and played in Washington D.C. in May 1985: The 1982 release of Fantasia was the first soundtrack recorded digitally.

I distinctly remember the LA Times doing an article about it. I have it stuck in my head that they were using a VCR synchronized to the film playback, something along the lines of the old Corvus Mirror, which could store digital data on a standard VCR. Anyone know for sure, or am I hallucinating all this? As far as early digital recordings of film soundtracks, Star Trek The Motion Picture had a digitally-mastered soundtrack. It came out in 1979 of course. I don't know if that's the earliest digitally-recorded movie soundtrack, but it's gotta be *one of* the earliest.  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 08-05-2003 03:23 PM                        Yes. The system used to present "Fantasia" at the Century City Theatre was discussed in an interview published in Widescreen Review, Volume 2, Number 8. The 1982 performance conducted by Irwin Kostal was recorded digitally, and mixed by Shawn Murphy. The projector was interlocked with the two track digital master using proprietary syncronizers developed by Disney engineers (led by Nelson Meacham) for EPCOT Center. The "Fantasia" digital sound presentation opened February 8, 1985, and generated considerable interest and business.  |  IP: Logged Joe Redifer You need a beating today Posts: 12859 From: Denver, Colorado Registered: May 99 posted 08-05-2003 03:25 PM                        Wasn't Fantasia recorded in 1754 or whenever the movie was made? All I know is that it is horribly old. How did they record digitally back then? Or did they just rescore everything in 1982? No matter how great the sound is, I still hate that movie with a passion.  |  IP: Logged Stephen Furley Film God Posts: 3059 From: Coulsdon, Croydon, England Registered: May 2002 posted 08-05-2003 03:38 PM                     Joe, this was a totally new recording of the score. It wasn't very popular, and for the 50th anniversary release the original recordings were restored as best they could be from the best surviving elements. The original 'Fantasound' recordings no longer existed at that time.  |  IP: Logged David Stambaugh Film God Posts: 4021 From: Eugene, Oregon Registered: Jan 2002 posted 08-05-2003 03:39 PM                        I'm afraid I've never "gotten" Fantasia either. I want to appreciate the pretty images and nice music, but then I fall asleep.  |  IP: Logged Michael Coate Phenomenal Film Handler Posts: 1904 From: Los Angeles, California Registered: Feb 2001 posted 08-05-2003 04:35 PM                     quote: That 1982 release of Fantasia may have had the first digital audio playback in a theatrical venue. Yes, but who heard it digital at that time? For clarification... the '82 re-release used the new digital re-recording of the music, but the theatrical soundtrack presentations were in Dolby Stereo (some mag, most optical -- many theatres likely still ran mono). It was in '85, as mentioned by several in this thread, that an audience could actually hear the film played back digitally. quote: As far as early digital recordings of film soundtracks, Star Trek The Motion Picture had a digitally-mastered soundtrack. Again to clarify...I believe you're referring to the soundtrack album (i.e. the recording of the music score was digital), not the film's sound mix.  |  IP: Logged
