Author Topic: Video Projector recommendations Ron Curran Jedi Master Film Handler Posts: 504 From: Springwood NSW Australia Registered: Feb 2006 posted 07-27-2010 07:08 PM                        I agree with the posters who advise against spending more than $20K on a projector that won't allow you to show D-cinema files. One other annoyance is that all (?) of these machines expect you to change settings using an on-screen display instead of a monitor with the operator. Apart from the fact that you don't want an audience to see your fiddling, the displays are difficult to read from 20 metres away.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

Sufficient control systems should be in place to avoid that. We use things as simple as the "Buttonmate XL" from Mediatech all of the way up to Crestron or AMX though most seem to be Extron MLC series controllers like the MLC 226 IP Expand it with some button panels like the CM9BLB and you can control most Alternative Content stuff, including the projector. Heck you can have it email you when the lamp needs to be changed or the filters need cleaning...etc.  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA. USA (1774.21 miles northeast of Dallas) Registered: Jun 99 posted 07-27-2010 10:50 PM                        The Panasonics have a network card (usually an option, but standard on some models) and a web interface. The interface itself is a bit awkward, but it does allow all settings to be manipulated without showing any sort of display on the screen. They also have mechanical dousers to make possible an easy "changeover" from film to video or vice-versa. (I have never seen a video projector douser wired into the film c/o and/or automation system, but it is possible to do so.) Sometimes I think that the industrial designers who are responsible for the exteriors of these things have gone off the deep end, though. The Epson that was mentioned earlier looks like a child's sled. The Sony VPLFW300L looks like a footstool. And the Sony VPL-FX52 looks like a flying saucer.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

Note, some Sanyo models, like the PLV-WF20 have mechanical dousers now too.

At the stsrt of the 35mm presentation, the shutter closes. Works perfectly with no light on screen while the lamp cools down. I understald there are the next generation available with little to no cool down. 8 meter screen with a 10 meter throw.  |  IP: Logged Chris Slycord Film God Posts: 2986 From: 청주시, 경북도, South Korea Registered: Mar 2007 posted 07-28-2010 08:10 AM                     Maybe it's just me, but why would you need a mechanical dowser? Couldn't you just trigger the vid proj to shut off for a changeover or have it switch to a pattern of black while it cooled off in case immediate shut-down wasn't possible?  |  IP: Logged Paul Gordon Jedi Master Film Handler Posts: 580 From: Ottawa, Ontario, Canada Registered: Aug 2005 posted 07-28-2010 08:47 AM                        black is never black  |  IP: Logged Martin McCaffery Film God Posts: 2481 From: Montgomery, AL Registered: Jun 99 posted 07-28-2010 09:16 AM                        To expand on Paul's reply to Chris: the video would be projecting "black" onto the screen, which means it would be projecting light. You end up with a projected square of light in the middle of your screen while the film is projecting. You have to be able to block or cut off the light source. If you are doing frequent changes from video o film, you don't want to turn off the video lamps and have to rewarm them every time you switch, so a douser of some sort is the best option.  |  IP: Logged Kirk Futrell Film Handler Posts: 95 From: Nashville, TN / U.S.A. Registered: Nov 2008 posted 07-28-2010 10:36 AM                        We have a mechanical dowser on our video projectors. It won't work for everyone, though. Its my arm connected to a large piece of cardboard... When folks look back at the booth they are dazzled by the ingenuity and professionalism.  |  IP: Logged Martin McCaffery Film God Posts: 2481 From: Montgomery, AL Registered: Jun 99 posted 07-28-2010 10:41 AM                        We have the same douser!  |  IP: Logged Chris Slycord Film God Posts: 2986 From: 청주시, 경북도, South Korea Registered: Mar 2007 posted 07-28-2010 11:37 AM                     Fair enough, though I was thinking that in most situations you could just as easily trigger the thing to shut the lamp off.  |  IP: Logged Kirk Futrell Film Handler Posts: 95 From: Nashville, TN / U.S.A. Registered: Nov 2008 posted 07-29-2010 09:40 AM                        Which technology do you prefer for life-cycle costs. I have heard of and experienced problems with LCDs. I have an 11 year old Proxima from 2000 that developed spots on the image, that weren't on the lens. A Sanyo that has developed what looks like 2 or 3 "bubbles" on the image. An 8 year Eiki 4000 lumen, that has had the blue LCD replaced to the tune of about 1500 bucks and a couple weeks out of town at the shop, as well as its most recent development of a blue cloud that takes up about 10% of the image near the top center (delamination?), which looks awful when you are trying to show black and white trailers. What are the things that need maintenance or replacement in DLP's? What problems are associated with them as far as image degradation or service life goes?  |  IP: Logged Victor Liorentas Jedi Master Film Handler Posts: 800 From: london ontario canada Registered: May 2009 posted 07-29-2010 12:41 PM                     I also have this futuristic dowser! I dislike the LCD machines for the reasons stated above plus i always notice a yellow tint over time even with a new bulb. One of my theaters uses a 720p 3 chip DLP Infocus 777 and a new bulb restores the like new brightness! After 3 years i see 0 degradation of the picture! Cost new was just under 10 grand.  |  IP: Logged Martin McCaffery Film God Posts: 2481 From: Montgomery, AL Registered: Jun 99 posted 07-29-2010 01:32 PM                        Kirk's problems with the Sanyo sound like the same problem I had, which was the result of one of the lamps (ours has 4) developing a bubble. Take the lamps out and take a look at them to make sure they haven't developed any deformities.  |  IP: Logged
