Author Topic: CYAN DYE tracks FACTS OR FICTION Frank Jerkic Film Handler Posts: 77 From: Ayr Queensland Australia Registered: May 2004 posted 05-24-2004 09:50 PM                        Hey There Everybody, Well today 20/5/04 I recieved a letter from Buena Vista advising all us cinema owners that they are making the switch to cyan dye tracks. The first movie will be Mr. 3000 released on September 24 and you MUST have a projector equipped with a visable red light analog reader or you will have NO SOUND This has caused a great deal of panic with some exhibitors rushing out spending $1,000 per reader per projector Is this no sound true or is it just a con? I have 1 Kaylee (for Drive in) and 2 Century projectors (Cinema)to convert, any ideas on what's the cheapest way of doing this as I hear of easy do it yourself laser ideas but........... We were told that this new sound would be in place by 2000 but nothing happened,Australian Film distribitors know nothing about it, now Disney is the first to change will others follow. Thanks for any help Frank Nth Qld Australia  |  IP: Logged Mike Blakesley Film God Posts: 12767 From: Forsyth, Montana Registered: Jun 99 posted 05-24-2004 09:57 PM                        It's not that you'll have NO sound. You'll probably have very POOR sound. For more information see this thread: http://www.film-tech.com/ubb/f1/t005104.html  |  IP: Logged Randy Stankey Film God Posts: 6539 From: Erie, Pennsylvania Registered: Jun 99 posted 05-24-2004 10:05 PM                     It is true. Not only BV but MGM will be going to 100% dye tracks. It is NOT true that you will get *NO* sound. Yes, you will get SOME sound but it will be crappy. It will have low level and poor quality. This only applies to analog sound. Digital sound systems will be unaffected. Thus, if you play 100% of your shows in digital formats you will be able to play normally UNLESS your sound system falls back to analog. However, if/when you do fall back to analog your sound will go to shit. I don't know about the $1,000.00 price tag. Maybe. I just don't know for sure because I haven't priced that stuff in a long time. It depends on what kind of deal you can make with your equipment distributor. I'm sure others will be along shortly to fill in the gaps.

Donno about your currency and such down there. DOesn't Panastereo make a nice reader?

More trouble than they are worth. Get the real conversion. Once you do, you won't have to worry anymore. Furthermore, with a good reverse scan conversion package to red LED, A-Chains will be a breeze! (Once properly installed.)  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 05-24-2004 11:17 PM                        The published paper by Paul Goldberg says the signal level of a cyan dye track on a tungsten reader will be about -11dB in level: http://www.dyetracks.org/ci.os.0012.reddye.html quote: As you can see, the tungsten reader reproduces a cyan dye track print with a loss of ~11 dB, whereas the red LED reader reproduces cyan track and silver track prints with almost equal amplitude. In other words, on a tungsten reader, a cyan dye track will require increasing the gain considerably, with a resultant increase in noise. This is because the cyan dye is essentially transparent to infrared energy, and cannot modulate it efficiently.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

So, our friends down under have a 42% price hike on anything coming out of the states just to get it to their country. Then add on any tarriffs, freight...etc...lastly the dealer mark up and before too long...you are at a high price compared to what you may be used to in the States.

Have you considered laser cyan conversion kits ? No preamp, last forever... TO be fair, we sell a laser kit but there is one other on the market too which I believe is OK. Pricing £GBP360 for one of ours, which I believe fits straight into a Kalee lens holder (do you know the diameter ?). Does the Kalee have a photo cell or a valve pickup ? God knows how a tube would react to white thru cyan light.. But hey, a drive in with a Kalee 1 - no offense but I guess mono sound from a pre Dolby system - if it has plenty of gain up it's sleeve it might be worth taking to BVI and getting a sample to run. But it is a bit naughty of them to tell you that you will have no sound.. Re Jaxlites, I can't really comment but I know a few of our clients have taken them out and installed lasers.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 05-25-2004 11:36 AM                     What model soundhead is the Kalee 1 mounted on CE makes a reverse scan basement reader for the Gaumont Kalee soundheads that were used on the 19-21 projectors  |  IP: Logged Steve Kraus Film God Posts: 4094 From: Chicago, IL, USA Registered: May 2000 posted 05-25-2004 11:49 AM                    I'd still like to know...just for curiousity...what level can be attained by cranking the heck out of an incandescent bulb (considering normally they are undercranked) even at the cost of greatly reduced life and increased chance of failure...and upping the preamp gain. I may have to set up one of my incandescent Century soundheads to find out. If only they would make some cyan trailers as has been suggested over and over.  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 05-25-2004 11:54 AM                        Just upping the tungsten light level is not a "fix" for the low level. You need to eliminate the infrared energy to which the cyan dye is transparent. The cyan dye very efficiently modulates the red light, but the infrared energy just goes right through the track.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 05-25-2004 11:58 AM                     At Showest one year Kinoton had a quartz lamp conversion with a presion dichoic filter that they claimed would work  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 05-25-2004 12:02 PM                        I assume this is the Kinoton unit?: http://www.kinoton.com/rotlicht.htm http://www.kinoton.com/tontechnik.htm  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!
