It was the film "Days of Thunder" that had the massive failure at Mann's National Theatre in Westwood. I believe it was a heat issue of the unit in the booth.

Another problem on the West Coast in the Southern California area during "Dick Tracy". Was NFS mixed print reels and sent CDS prints to theatres that were to get mag prints. And mag prints to CDS houses. Sounds like these people now work for TES [Big Grin] .

Thanks for remembering the specifics around this incident of hardware failure (overheating) I referred to in my original posting on this thread. Word of failure in a "high profile" situation like this spreads very quickly. Another $10 muffin fan may have changed the course of digital sound history, maybe for the better. [Wink] But Cinema Digital Sound DID pave the way.

Time and time again, "Dual Inventory" has shown itself to be unmanageable when more than a few prints are involved.

The national film board of canada unveiled a digital system that overlaid the digital track ontop of the analogue track with a reverse scan beamsplitter based reader in the cnetury r3 soundhead
There was a SMPTE article about the system

Now, John... didn't you just suggest in another thread that I maintain dual inventories with the Screen Attractions prints? See, it's more trouble than it's worth, particularly in my case with the red-reader optimized soundtracks, since exciter lamps are on the way out.

Tim:

That's the point. Today we have a MIX of white light and red LED readers. So traditional (cyan+magenta+silver) tracks have different cross-mod optimization points, and ideally require dual inventory, and the problems that entails. Without dual inventory, one or the other reader will have some sibilant distortion. High-Magenta (magenta+silver) are more compatible with both. And with cyan dye only tracks, you can only use a red light reader, so no need for dual inventory.

If NT Audio and the lab optimized your prints for red LED readers, you're all set for the future.

John--can the same optical track negative be used to make silver, high-magenta, and cyan tracks, or are there other differences before the printing stage?

(yes, this should probably go in the dye tracks thread)

without reference to that paper, which i probably wouldn't bother to read anyways, i fail to see how a digital track could be overlaid on a conventional optical track. does it only work on a cyan track, with the digital track printed say, in magenta? if so, that seems like a damn good idea (pending advancements in leds) that would keep the digital soundtrack in a less-abraded area.

FYI - The CDS equipment is still sitting at the UA Bethesda location in Maryland. It's no longer hooked up, but it's still there holding the floor down.

For optimum results, the sound negative exposure (density) is optimized for the type of track. It's likely that old sound negatives originally made for dye+silver tracks would still be used to make dye+silver prints, but with Cross-Mod optimized for red LED readers.

To answer Carl Martin's question, I'm not sure the NFB system was ever used for a feature release.

Final off-topic post by me in this thread... John P. said:

That is only a temporary condition. Don't forget, these prints are designed for long-term usage, and are expected to be on screens for years to come. It is pointless to maintain a stock for a scanning system that has its days numbered. If we were a studio with an entertainment product that is here today, gone tomorrow, I would be inclined to agree with you. But it just doesn't make good economic sense for this application.

Tim:

If you had your silver+dye prints optimized for red LED readers, you made the right decision, since red readers are in the clear majority now. If they are "high magenta", they should be pretty compatible with tungsten too. If they are cyan+magenta+silver, they may have a bit of sibilance on tungsten readers.

BTW, I can't stand the AMC Century City 14. I can't believe that so many people (in hollywood!) would want to wacth a movie in such small thatres with tiny screens, awfull sound, and projectionists who cant seem to focus for ****. AMC should bulldoze that sucker and rebuild a nice theatre in its place.
You want tiny screens? Check out the Cineplex Odeon in The Beverly Centre. Teensie-Weensie theatres....but then you have to remember that the folks in Beverly Hills are used to cozy little screening rooms.

Darryl said: "Fantasound ended in 1941 and would not be heard again until a remastered version in Dolby Stereo was recorded in 1982 with Irwin Kostal conducting the Stokowski arrangements."

Not quite true; FANTASIA was rereleased quite a number of times over the years, one notable release was an anamorphic version that, although the animation was distorted by the bizzare attempt to make them "scope" and morphing everything that was round into obvious ovals, the soundtrack was a 4 track mag record of the original multitrack optical recording. The 1 sheets for this release (circa 1955) claimed "In FantaSound."

This unfortunate release in pseudo-scope was just a bad idea based on worse marketing -- the idea being that wide screen had become a sizzling hot item at the time and here was a way Disney could capitalize on it and add the original stereo (Fantasound) to the print via mag tracks. They claimed this version of FANTASIA was in Superscope.

Now, if it were JUST a straightforward playing of the 1.37 print with an anamorphic lens, the savvy exhibitor could simply play it without the anamorphic attachment and he'd get the original image plus the 4 track mag sound. Good enough. But as it turned out, the studio decided (very wrongly IMHO) that they could get away with stretching out the animated segments, but not the human beings. So they optically compressed all the live action sequences, deleted all the Deams Taylor segments (they needed to get rid of the need to lipsync -- more on that later) that joined the animated works together and then, when the animated sequences began, they did an optical spread out to full frame width, which, of course, would then become "scope" on the screen. Everyone included me saw the insanity of that version, but if you wanted to run FANTASIA in stereo, it was the only print that had the original stereo. So, how to get the stereo sound and not the distorted "scope" image?

Our solution was to use a Superscope variable anamorphic lens (having nothing to do with the Disney claim that the film was in Superscope). For the live segments which the studio optically compressed on the print (projected with a normal anamorphic lens, they appeared on the screen as a normal 1.37 image), the Superscope lens would be set to standard 2x stretch. But when the animation came on and the studio did an optical to gradually returned the image to full frame, I manually decreased the anamorphic stretched to zero, leaving the normal 1.37 image on the screen. After a few shows, I was able to time dialing down the anamorphic stretch to zero or back to full 2x to match the optical stretch or compression on the print; most of the time the audiences noticed no change at all on the screen; with this method, I could play the film in 1.37:1 without any of that anamorphic distortion nonsense but get the 4 channel original Stokowski tracks. What we won't do to get stereo sound!

"Wasn't Fantasia recorded in 1754 or whenever the movie was made? All I know is that it is horribly old."

Ehem....Age isn't necessarily horrible and by the standards of the day (1939), FANTASIA was one of the most daring and inventive cinema works to ever come out of the Disney studios. It INVENTED technology to present stereo sound a decade before its time. And the animation was astonishing, again for its time -- nothing like this had ever been attempted before.

For those born forty years later, it may not have the eye candy that is common-place with today's computer generated images, but it broke all kinds of new ground in its concept and execution in its day. In fact, it wasn't supposed to be a "movie" at all, but a new kind of movie concert.... a Fantasia. The idea was that the Disney studios would continually create new animation and Stokowski would record new symphonic works. The older segments of the film would be pulled and the new ones inserted; people would be able to go to a Fantasia Theatre as they were to be called, and see FANTASIA with new works in it. Because of the staggering economics and sheer size of the system, it was a financial disaster and studio abandoned any further work.

The marriage of music and animation stands alone to this day, regardless of how many "music videos" are churned out like so much manure from the great ass of Hollywood.

It is said that Walt Disney went into a deep depression when his idea of a movie concert and the film itself were so roundly lambasted by the critics. To his death, he claimed that FANTASIA was the work he was most proud of and most dear to his heart.

"No matter how great the sound is, I still hate that movie with a passion."

Interesting; could you tell us why? Perhaps it doesn't rise to the level of Hip Hop videos? A little respect might be in order for the accomplishments of the movie pioneers of the past.

"Yes, they just had an orchestra play the same score "synched" as best they could, because it would be NEW AND IMPROVED!

The original animation was made to bar sheets & the recorded track, & edited after shooting. It was tight, like sound & image are with classic Disney & WB cartoons. The new score was done the other way around, like Fleischer (Popeye) cartoons, trying to stay synched to the picture. Not only was the orchestral performance pretty mediocre, but the sync was mostly off, sometimes way off. It was no longer a cool theatrical experience of musical & visual unity.

I saw it, it stank. Real bad."


Perhaps you saw what was an unfortunate problem that dogged the 80s digital presentation of the Kostal rerecording. At the time the studio recording was digital, but you have to remember that as yet there was no digital on film -- No Dolby D, no DTS, no SDDS and even no CDS. The digital system that played in the major markets was interlock (sort of) with a Sony PCM deck.

The print was run from a platter and projectors were equipped with synchronous motors; the PCM deck just ran on the fly. They were started together, but once they were going, it was pot luck - the projectionist at the Zeigfeld in NYC said they would stay in sync MOST of the time, but he said that when they would drift, it was his job to manually switch back to the analog track if he though they were noticeably off. It was his call, and from my discussion with him, he seemed to be of the mind that you couldn't tell if the music was out of sync with animation. "After all, it doens't have to be lip sync....no one is talking." Hence the reason behind deleting the Deams Taylor sequences -- no lipsync issues on his closeups. And you had to wonder how closely projectionists paid attention to the screen at anyone given moment anyway. Who know how far adrift sound and picture where when you saw it.

And I disagree that the Kostal score was not "tight;" I ran that very 1982 Kostal print last year, playing the analog Dolby A stereo track, and except for the obvious improvement in fidelity and the spatial width of the stereo soundfield, Kostal's conducting was very true to the Stokowski interpretation and it was perfectly synced to the image. In fact, in an interview Kostal gave, he said he knew what he was up against in terms of the negative comments that would come from the purists who would have him drawn and quartered just because his recording was replacing the Stokowski recording. He admitted that it was very clear that his job was not to reinterpret Stokowski's original recording, but to match it and provide sonic clarity that was missing because of the technical limitation of the 1939 optical recording technology. And that he did, I would say, note for note, musical phrase for musical phrase.

To see the spectacular animation (hand painted, I might add with nary a single CGI frame in the whole film) married to an open, airy, full orchestral track was a rich experience. I have 3000 patrons who saw it in our open air theatre who seemed to feel the same. I also have the CD of the Kostal soundtrack and I certainly wouldn't characterize it as mediocre. It is perhaps not the best reditions of the works, but given the restraints under which the conductor was saddled, his version is as much a pleasure to hear as many other recordings of the same works that I have collected over the years.

Interestingly, almost every time I have booked that masterpiece (at least 7 or 8 times since about 1975), I would find patrons in their 20s and 30s who had never seen FANTASIA, asking "when did it come out...a few years ago?" I'd tell them, no, 1939; they invariably would register surprise that a film THAT OLD could look so fresh.

As far as I know, the first documented experiments with stereophinoc recording techniques took place in the early 1930s. RCA experimented with the 3-channel recording of a concert in Philadelphia and transmitting it to New York.
During the war, the Reichsrundfunk in Berlin also made test stereo recordings which I heard and which sound astonishingly good for their age.
Still, Fantasia was the first ever movie to be presented in stereophonic sound and the technical achievement is quite impressive.
