Author Topic: Cyan Dye Track Experiences with "Anything Else" Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 09-21-2003 07:42 PM                     quote: Wow! The world has not ended, and the sky has not fallen. Let's toast with a glass of pure, clean water. No the world has not ended...just downgraded and once again people are made to settle for a little less (on this film). You and the rest of the reckless dye-track people have yet to provide any long-term knowledge of the cyan dye-track's performance. I was merely reported the facts as I saw them...the purpose of this thread. Keep your enviro-wacko opinions to the other thread.

Is the error rate OK? OR -- should you really have a CAT-701 or 702?  |  IP: Logged Darryl Spicer Film God Posts: 3250 From: Lexington, KY, USA Registered: Dec 2000 posted 09-21-2003 11:41 PM                    Ran our print using the JAX light system. No apparent noise noticed and the levels matched the levels of the DTS soundtrack. DTS timecode ran without any problems.  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 09-22-2003 05:48 AM                        quote: Has anyone tried the cyan track with the CAT-700 white light readers?

AFAIK, the Dolby Digital (SRD) color balance is still being optimized for both tungsten and red Dolby Digital readers. As previously discussed, the color balance of the Dolby Digital track is a separate issue from cyan dye analog tracks. The Dolby SRD track NEVER required silver redevelopment.  |  IP: Logged Jason Black Phenomenal Film Handler Posts: 1723 From: Myrtle Beach, SC, USA Registered: Nov 2000 posted 09-22-2003 08:40 AM                        I have this print as well. We've run it in DTS thusfar, but today I plan to let it run with the infrared and have a listen. The film, after all, isn't one that is garnering much attention (in my area) which is probably the reason behind making it the first all cyan dye track print... ??? Will report back later on what I find..  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 09-22-2003 10:21 AM                        Jason Black wrote: quote: ...but today I plan to let it run with the infrared and have a listen. Did you mean red LED? Or are you using an infrared source (e.g., infrared LEDs)? A cyan dye track requires a RED reader, or else it will have low level and be quite noisy.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 09-22-2003 11:28 AM                     "You and the rest of the reckless dye-track people have yet to provide any long-term knowledge of the cyan dye-track's performance." ______________________________________________ I got a good laugh out of this one! I guess Steve, thats what they are now in the process of......developing that long term knowledge base on Cyan Tracks. Its about impossible to develope any long term meaningful knowledge on them without putting the thing in a general wide release so everyone gets setup for exposing any booby-traps. In fact, the tighter processing control which Cyan Tracks require JUST MIGHT RESULT in nicer looking images on release prints in the long run. Since most sites that have any box office income meaning are playing back in digital the nicer images would be a big bonus. So far cyan has been zero trouble in this area except for a few locations needing to be converted at the last min. Of course I sometimes reflect back on all the re-developed tracks I have heard over the years that were the culprit of bad bearings on the re-development rollers....that grind-grind noise you got from them........ Steve, Every process has its faults...nothng is perfect....

It has played in DTS, so we haven't noticed any problems. I don't recall what house it was screened in but my operator didn't report any unusual problems relating to sound level(s) on screening. Will test it today to see what sound 'nuances' the infrared LED yields.  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 09-22-2003 12:10 PM                        Jason: If you play the cyan dye analog track with an INFRARED LED reader, you should get about the same results that Michael Schaffer did --- a low signal level (~11dB) that requires you to increase the gain, and significantly more noise (more than just a "nuance"). Fortunately, you evidently have rare default to analog with your DTS system, which already uses a red LED to read the DTS timecode.  |  IP: Logged Steve Kraus Film God Posts: 4094 From: Chicago, IL, USA Registered: May 2000 posted 09-22-2003 03:03 PM                    John reminded us: The Dolby SRD track NEVER required silver redevelopment. Maybe it should have, John! Maybe a silver applicated SR•D track and a white light reader would give everyone error rates of 0 and 1!  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 09-22-2003 04:24 PM                        Applying a viscous bead of caustic developer over the perforations in a precise manner on film traveling through a processing machine at hundreds of meters per minute? Messy. Can you say "splash"? I see images with silver polka dots. Dolby did the right thing using sensors sensitive to mostly visible light, and then red LEDs.  |  IP: Logged Joe Redifer You need a beating today Posts: 12859 From: Denver, Colorado Registered: May 99 posted 09-22-2003 04:47 PM                        Bah! All this talk of silver sickens me. Everyone knows that the entire print should be made out of pure asbestos.  |  IP: Logged Steve Kraus Film God Posts: 4094 From: Chicago, IL, USA Registered: May 2000 posted 09-22-2003 06:24 PM                    I think Joe is a vampire, afraid of silver. But anyway, they should go back to printing SR•D with white light. If it aint broke don't fix it and to the extent that there is any difference that is what everyone has adjusted for.  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 09-22-2003 09:13 PM                        As I said, Dolby is working with the labs to verify the best color balance for the Dolby Digital SRD track for both tungsten and red LED readers.  |  IP: Logged
