Carsten, does that comment imply that to use the Barco laser kit that the Alchemy IMS whatever-they-want-to-call-it must be used?  |  IP: Logged Marcel Birgelen Film God Posts: 3357 From: Maastricht, Limburg, Netherlands Registered: Feb 2012 posted 05-09-2015 01:14 PM                     As far as I understood it, yes, you must use their Alchemy IMS bundled with their Alchemy IMB solution for now, because no other IMB is compatible with this machine. Maybe other IMB suppliers will come up with compatible devices in the future, but since the IMB is part of the bundle, I guess not much suppliers really feel the need to build an IMB for those projectors. Also, the SDI inputs currently do not work either and will probably never be capable of doing DCI sanctioned crypto either.  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 05-09-2015 01:58 PM                     Wow. They just shot themselves in the foot.  |  IP: Logged Lonny Jennings Film Handler Posts: 10 From: Boston, MA USA Registered: Feb 2000 posted 05-09-2015 03:42 PM                     My first choice would be common height with side masking and an anamorphic. Second choice would be a 1.89 screen with side and top and/or bottom masking. With this setup there is no light change between formats; in fact, there is no change in the lens at all! Same zoom, focus, shift for all formats. For the larger Christie projectors you can leave off all of the adjustment pieces on the lens. On the Solaria you don't have to do anything; set it up and it's good forever. For the Barco and NEC you don't ever have to worry about the lens settings drifting over time.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 05-09-2015 04:14 PM                     I guess that the Alchemy needs to go into all current Barco 6P LIPs. Probably also because they need that specific functionality for the spectral separation 3D, and 4k/60fps. I don't know, but doubt that this is also a prerequisite for their retrofit laser light source once that becomes available. That would make the economics of the laser retrofit quite problematic right from the start. - Carsten  |  IP: Logged Marcel Birgelen Film God Posts: 3357 From: Maastricht, Limburg, Netherlands Registered: Feb 2012 posted 05-09-2015 05:57 PM                     The Cinemechanica laser retrofit claims to work with "any" DLP projector and should work with any common server. I guess their "laser box" does have either an Ethernet or serial interface you can communicate with, using some simple macros. It's indeed the non-standard DCI stuff that requires the Alchemy IMB, like the 3D 4K HFR thing but also the "HDR"/wide gamut support and probably the interfacing with the LIPs too. I'm also not all that pleased with projector manufacturers starting to push their own IMSes. In my opinion a projector should do exactly what it's supposed to do: project images. Playing the actual content should, preferably, be done on a seperate player device using a generic interface... Then again, Barco is surely moving into the direction of building "one stop shop" solutions, where they supply projector, "server" and the sound system. That's probably also why Dolby joined with Christie and created this "Dolby Cinema" concept.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

But you have to start somewhere, particularly for an esoteric piece that costs as much as it does. Note, they are strange bedfellows since Christie has gone into the sound market as well as server market...both existing Dolby markets. Though Dolby is not known beyond the processing stage (they own SLS speakers now). They are one of earliest server companies and just bought Doremi, the biggest installed base of servers with OEM deals for both Barco and NEC and even LieMAX (not Christie). Since the Barco Alchemy fits in the standard slots used by the ICP and the HDSDI/IMB slot. Also remember, post still uses quad link a lot...hence Barco (And the others) make a quad link input board...for that to be usable, one would need to have the projector work with the standard ICP and an HDSDI module. However, Christie threw down the gauntlet with the Solaria 1/1+ that HAD to use the IMB S2. There was no reason for this...there is no way there was a "cost savings" by excluding others. What Barco has done with the Alchemy was to not be constrained by the bandwidth limitations of the ICP. The question still remains if they are a good server company...I generally don't like to fool with things where a company is "dabbling" in an industry that they have no credibility in.  |  IP: Logged
