Author Topic: Muting eye/lens on Sony SRX-R320 3D Lens Matt Skilton Film Handler Posts: 43 From: Bromley, Kent, UK Registered: May 2009 posted 08-30-2011 04:58 PM                        I've got a special event next week and it will involve using our Sony SRX-R320 projector to display third-party content via the DVI input. However, the lens on the projector is the 3D lens and I've been informed that this may reduce the quality of the presentation. I've heard about being able to mute one of the eyes/lens' which will help. Does anyone have any experience doing this (i.e how to actually do it) and any tips to get it looking as good as possible with the 3D lens?? Thanks for any help.  |  IP: Logged Chris Slycord Film God Posts: 2986 From: 퍼항시, 경상푹도, South Korea Registered: Mar 2007 posted 08-30-2011 05:15 PM                     Your options are (AFAIK): 1) Change out the 3D lens for the 2D lens 2) Make the bulb run hotter/brighter to cover for the fact that the 3D lens will lead to light-loss.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 08-30-2011 05:49 PM                     Not even .. leave the lens setup alone. If you wanna play safe, put a new bulb in. "Yellow Journalism" really gets spread around by the media and hurting the cinema business with what they think they know. If you're doing VGA or other output, you need a scaler to convert that source to a DVI out. Sound just patches in on the Non/Sync of the processor.  |  IP: Logged Ken Lackner Phenomenal Film Handler Posts: 1907 From: Atlanta, GA, USA Registered: Sep 2001 posted 08-30-2011 06:55 PM                     Pretty much what Monte said. If the lens was installed properly and the convergence is nice and tight, all formats will look great. If not, all formats -- cinema and non cinema -- will suffer. All that needs to be done is to set up a projector Function that uses Input A, which is DVI. If you are not familiar with SRX controller and/or authorized to make configuration changes to the projector, you should leave this to a technician.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 08-31-2011 04:22 AM                     Get a notebook or Desktop computer in the booth with DVI Out for a quick test before. If you feel good about playing 2D content through the 3D lens - why should you bother? If you're concerned about DVI image quality through the 3D lens - you should be concerned about leaving the 3D lens on the unit for 2D cinema content just as well. - Carsten  |  IP: Logged Edward Havens Jedi Master Film Handler Posts: 614 From: Los Angeles, CA Registered: Mar 2008 posted 08-31-2011 11:56 AM                     If it's truly a special event, a showing that someone is paying your cinema a fair amount of money to hold, it is your cinema's responsibility to give those people the very best presentation possible. And if that means swapping out the 3D lens for the 2D lens, even if it means having to spend some time recalibrating the 3D again when you swap the lens back in after the event, so be it. And frankly, I am honestly shocked anyone active in this forum, people who are supposed to be for giving customers the best presentation possible, every single show, no matter the format or equipment used, is brazenly suggesting it's okay to just leave a lens on that is proven and acknowledged to degrade light output. It doesn't matter if it's 80% or 20%, someone who is paying you to show their movie deserves nothing but THE ABSOLUTE BEST presentation possible. I mean, we should be doing that regardless the circumstances, but it shouldn't even be a question if your theatre is being hired for an event. The mere suggestion of willingly giving a less than best presentation makes me  |  IP: Logged Chase Pickett Expert Film Handler Posts: 142 From: Irving, Texas, USA Registered: Nov 2010 posted 08-31-2011 12:06 PM                     I'm with Edward on this. Swap out the lens. Putting in a fresh bulb and leaving the real D lens installed still won't give you near the light as swapping in the 2D lens. Also, muting an eye does not have a profound effect on light output. In fact I've only seen a very slight change in light output with an eye muted. Swapping out the lens will take you 20 minutes without you doing it before. Just make sure you have either your tech there to do it or the proper password to be able to get it calibrated properly.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 08-31-2011 02:21 PM                     quote: Chase Pickett Also, muting an eye does not have a profound effect on light "BZZT! Wrong answer, Hahns!" Since the unit only has the one chip and both images are being used from that one chip, you mute out one eye, your light output drops in half. Ever cover up one eye when you're shooting a 2d image on a screen and see how the pict suddenly drops in light quality? Also, who has the tonnage of fundage to purchase a single lens setup from Sony? Hope the pockets are lined with green to do so. You'll be fine with a twin lens setup for your event... -Monte  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

Playing a movie and putting up static images are two different animals...the static image is harder as the eye is more apt to pick off the problems. Put up a 1-pixel wide cross hatch pattern and go down to the screen and see just how well those two lenses are converged over the ENTIRE picture. Depending on the type of images being put up the problem of imprecise convergence of the two images will either be a big deal or not-visible (if you have a power point with big blocky letters...anything will do). Next comes the resolution...what is the source resolution? A Sony with the 3D lens in place is only an 858 pixel tall projector...sufficient for XGA (1024x768) but insufficient for 1400x1050, 1920 x 1080 and a host of Mac formats. With a 2D lens, you should be able to output pixel for pixel most any format the computer walks in with since you have 4096 x 2160 pixels available. Ever used the digital keystone corrector when displaying from a computer source on a data projector? You move that one tick and the picture immediately smears. On a movie, you are not going to notice it nearly as much as if someone has some picture or drawing up on that screen. So...when a Sony gets a signal on the DVI connector...does it scale it to fill the imager or does it just put up a pixel-for-pixel version (or do you get a choice)? -Steve  |  IP: Logged Chase Pickett Expert Film Handler Posts: 142 From: Irving, Texas, USA Registered: Nov 2010 posted 08-31-2011 04:39 PM                     quote: "BZZT! Wrong answer, Hahns!" I was speaking in the adverse. As in it does not increase light and I was being a bit facetious.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 08-31-2011 05:32 PM                     An external scaler box, connected inbetween the source output and DVI out to the projector when programmed, scales up the image to fill the portion of the chip for twin lens usage. One of these devices is what you need. Course, this device is for VGA computer output and not for composite.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 08-31-2011 06:59 PM                     How about you rent a DLP and do the job right instead of just getting by???
