Author Topic: CYAN Finally breaking through Jack Ondracek Film God Posts: 2348 From: Port Orchard, WA, USA Registered: Oct 2002 posted 08-13-2005 02:40 PM                        Is there any information out there about when (if) any of the other major studios will be adopting cyan? After all the wailing and knashing over this (and we made sure we were ready well before the first one came out), it sure seems strange that the studios are moving so slowly. Will this be something the exhibs will remember, when the next technological gee-whiz comes along?  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 08-14-2005 07:18 PM                        quote: Jack Ondracek Is there any information out there about when (if) any of the other major studios will be adopting cyan? Ted Costas of Dolby is probably most aware of the studio plans for conversion to cyan dye analog tracks. I see Sony is on board with "Bewitched".  |  IP: Logged Thomas Dieter Expert Film Handler Posts: 234 From: Yakima, WA Registered: Jun 2004 posted 11-18-2005 12:01 PM                     I was wanting to know if anyone has had ever noticed, or had a problem with the Cyan track being larger than your traditional silver dye tracks. It seems to me that all our prints we get end up having a cyan tint on the left hand side of the screen. Not noticable in dark scenes, but it is in lighter scenes.  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 11-18-2005 12:26 PM                        quote: Thomas Dieter I was wanting to know if anyone has had ever noticed, or had a problem with the Cyan track being larger than your traditional silver dye tracks.

Check your projected image area with the SMPTE 35-PA test film (RP 40). The actual printed area for the cyan track is identical to the old dye+silver track -- it's done on the same printers from a sound negative exposed on the same equipment, so the position did not change. But since silver is not being developed in that area, the analog track is cyan rather than dark magenta or blue. So if you are accidently showing the track area, it is more obvious. If anything, the old silver application sometimes intruded into the picture area if the soundtrack developer spread into the wrong area.  |  IP: Logged Demetris Thoupis Phenomenal Film Handler Posts: 1240 From: Aradippou, Larnaca, Cyprus Registered: Apr 2001 posted 11-19-2005 06:58 AM                     I previewed an old Greek Film from the 70's, one of the first coloured greek films in a friends cinema where I converted it to a BACP Reverse scan and it sounded perfect. Crisp and crystal clear with no distortion. I am not really sure why some say that it creates a problem with old/classic films. D  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

It can be so bad that shows are cancelled (though I haven't found it to be that bad I have had some pretty strong complaints...so strong, we have converted the room to IR LEDs to avoid the problem...in fact they universally claim that all films now sound better). If you have an original DTS Buzz and Bill film (ours is from the 1993 era so I don't know if they have updated for high-magenta or cyan) then that film can really show the cross mod distortion...just run it in plain old "A" NR as it was recorded and listen...very harsh....then play it with either white light or IR and give it a listen...very clean.  |  IP: Logged Bill Enos Film God Posts: 2081 From: Richmond, Virginia, USA Registered: Apr 2000 posted 07-25-2006 03:18 PM                     We just played House of Wax 3D. The sound on our red readers was very screechy until we put a blue gel in the light path. Sounded normal with the gel...had to bump the volume from 6 to 8.5 to compensate though.  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 07-25-2006 03:45 PM                        quote: Bill Enos We just played House of Wax 3D.

If you have red LED readers, all that a blue gel will do is attenuate the light level. The red LEDs used in name brand readers have a relatively narrow output spectrum, centered near 660 nm with little light outside the 600-700 nanometer range. So I'm a bit surprised that a blue gel would affect image-spread related distortion. Do you use a name-brand red LED reader, or is it "home brew"?  |  IP: Logged
