Author Topic: LED readers Frank Angel Film God Posts: 5305 From: Brooklyn NY USA Registered: Dec 1999 posted 05-09-2003 09:15 AM                        > I reciently talked with an editor for columbia motion pictures who was surprised that anyone still had a change over booth. < Check out the thread "Last night of the Change-over" on this forum. Just goes to show you that just because some hotshot works for Columbia Pictures or is a film editor doesn't mean he/she knows ship from shinola about the nitty-gritty out in the trenches. If you read the thread, it is obvious that there are a lot more change-over booths than he had a clue about -- many of them right in the big studio screening rooms. He doesn't even have to go to the trenches.....does he think the studio projectionist at the Columbia/TriStar screening room mounts a print on a platter for a one time, in-house screening for a few company execs?

That statement could have been in reference to "commercial theaters", not screening rooms and special venue applications. (Let's fact it, without Guttag's installations, 99% of all normal commercial theaters would be platters or extended reels of some sort.) I have a feeling that statement from the editor was taken out of context. As for the cyan prints, I've given up on it, as I'm tired of hearing about the threat that at this point I don't think will happen. When the first batch of prints start showing up, then I'll worry about it. A properly calibrated digital system doesn't drop out anyway, so that gives plenty of buffer to play catch-up if the cyan thing ever really happens.  |  IP: Logged Phil Hill I love my cootie bug Posts: 7595 From: Hollywood, CA USA Registered: Mar 2000 posted 05-09-2003 08:03 PM                  Brad, you forgot my installations...it could ALSO mean special venue film loop cabinets and auto rewind systems thru the projector. That would make it about 92%. >>> Phil  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 05-09-2003 08:15 PM                     Brad, I think you'll find more C/O systems that you might expect out there. There are still quite a few in SLC. Most run off platters normally but the secons machine is available if c/o operation is needed. Mark  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

But such promotion is deceptive if it infers that these benefits stem from conversion to red light when in fact it's because of the reverse scan technique and that the absolute best analog playback comes from a modern reverse scan reader equipped with an IR LED playing a traditional (not high magenta) applicated track. Surely the entire truth should be told and let the chips fall where they may.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 05-10-2003 08:10 AM                     No I think the pull up on steves changeover browser was wrong and the missing ID frames caused it to repeat twice  |  IP: Logged Ray Derrick Master Film Handler Posts: 310 From: Sydney, Australia Registered: Sep 2001 posted 05-11-2003 06:20 AM                     I sat in on the ShoWest cyan dyetracks committee meeting also and was somewhat bemused by Ioan Allen's comment (and I hope I am quoting him accurately) "maybe we need to force them (the remaining theatres) to convert" (by releasing cyan prints now and causing havoc, particularly in those markets that are given rejuvinated prints). If Ioan was speaking on behalf of Dolby you can draw your own conclusions about that company's attitude to cinema exhibition in poorer countries. Sorry Ioan, but you said it. Also with all due respect to John P, who reported that distributors "expressed concern" regarding the distribution of cyan rejuvinated prints, my reading of what was said is more along the lines that several distributors predicted dire consequences for those markets using rejuvinated prints. I guess the interpretation of what was said is somewhat coloured by one's own views on the subject, true John? Personally I am in full agreement with Steve on this issue, despite the fact that my own company makes some good money out of Red LED readers. Plastic bags cause infinitely more damage to the environment than the comparatively tiny amount of chemicals used in redeveloping soundtracks, but do I hear the cyan proponents screaming from the rooftops about phasing out plastic bags? The whole thing is about a select few companies making some big bucks at the expense of good quality analog cinema sound and anyone who says otherwise is either fooling themselves or is in the queue for some of the big bucks.  |  IP: Logged Ken Layton Phenomenal Film Handler Posts: 1452 From: Olympia, Wash.

You're spot on.  |  IP: Logged Frank Angel Film God Posts: 5305 From: Brooklyn NY USA Registered: Dec 1999 posted 05-11-2003 11:14 AM                        Now if only someone would make a reader that you could easily switch from red LEDs to IR LEDs for the venues that program both retrospective and current titles. Will the solar cell in the red readers work with IR exciters or are they not sensitive to in the infrared range? My concern is for all the rep houses out there like ours that mix retrospective with current titles, and want to keep the reverse reader with white or infrared exciters for conventional prints, but are then in a pickle when the cyan tracks come along. Kelmar still stocks infrared exciters. I was toying with the idea of purchasing a pair and using them with the red readers. In other words, could I switch just the exciter when I need to play a cyan track but use the IR exciter for conventional prints? I imagine this would require an entire A chain alignment, right? An exciter array that contains both red and IR and is switchable would eliminate alignment and it would be a great boon for the alternative venues.

Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 05-11-2003 11:44 AM                     Frank, I don't think you have read my previous rants.... All of the solar cells used for optical sound reproduction, be they forward scan or reverse...ARE IR SENSITIVE...infact, the "red readers" are using an IR sensitive cell and hence one of the many reasons red readers are inferior. No matter how many times the cyan-morons dance around it, they canna break da laws o physics captn. As long as they use the cells they are using, Infrared IS THE light source, period...all others bring with them problems...the exciter lamp (tungsten bulb) works because of its IR engergy, not the other colors. The Component engineering LEDs are socketed but I wouldn't call them user changeable. The BACP LEDs are easily changed on their head mount...the head is socketed so rewiring is eliminated presuming the head can be wired for the different polarity...yes, I've found that IR leds are opposite to RED. Some of our rep houses are now IR LEDs and some more are switching (but keeping the visible RED LEDs at the ready if the ugly cyan crap does happen. Here is another IR benefit...those LEDS last MUCH longer than the visible LEDs and they are MUCH more stable...come back years later...Dolby Tone still on the money.

Play all features in Bypass You will see that all customers will notify the bad sound to the management.... You don't need to be Jackass' addicted on MTV to make that, but OMHO Is better to try to speak with the manager to explain how munch it's important to convert a theater for the cyan soundtrack  |  IP: Logged
