Author Topic: "Locking Out" Frame Rates? Jim Cassedy Phenomenal Film Handler Posts: 1661 From: San Francisco, CA Registered: Dec 2006 posted 01-14-2014 11:53 PM                     I have a couple of policy clip DCP's I created some time ago that were encoded at 30fps. (Before I knew better than to do that!) However, over the years, I've been able to play them at more than a dozen theaters in at least 3 different states with no trouble. However, I recently tried to use them at a theater here in San Francisco, and they would not work. A little red 'film frame' icon appears next to the clip name when you try to ingest it into the Dolby DSS 220 server. The projector is a Chritie CP2210. I can't recall if the IMB is a Christie or Dolby. Today I tried generating two short clips that were identcial except for that one was at 24fps and one at 30fps. The 24fps worked OK, and the 30fps didn't, at this one location. And yet at another theater with IDENTICAL equipment, BOTH frame rates play OK. So my question is: Is there some configuration setting in the projector, server or IMB that would "lock out" anything but a 24fps DCP? This is the only theater I've encountered that seems to have this quirk. I'm perplexed.  |  IP: Logged Justin Hamaker Film God Posts: 2253 From: Lakeport, CA USA Registered: Jan 2004 posted 01-15-2014 02:29 AM                        About a year ago we had to update our GDC servers to version 8.01 for DCI compliance. I haven't tried to play anything that is 30fps, but I wonder if it might be related to a similar update.  |  IP: Logged Antti Nayha Master Film Handler Posts: 268 From: Helsinki, Finland Registered: Oct 2008 posted 01-15-2014 02:47 AM                     Oddly enough, Dolby Cat 745 still doesn't officially support 30fps or 50fps even though Cat 862 does. I've heard conflicting reports about this in practice, though. Which Dolby System version are you running? Here are the current capabilities as listed in the release notes for 4.7.0.42: DSS200 or DSS220 with CAT745 IMB: JPEG 2000 4K 2D: 24, 25 JPEG 2000 2K 2D: 24, 25, 48, 60 JPEG 2000 2K 3D: 24, 25, 48, 60 MPEG2: 24, 25, 48, 60 DSS200 with CAT862 IMB: JPEG 2000 2K 2D: 24, 25, 30, 48, 50, 60 JPEG 2000 2K 3D: 24, 25, 30 MPEG2: 23.98, 24, 25, 29.97, 30 DSS100 with DSP100 IMB: JPEG 2000 2D: 24, 48 JPEG 2000 3D: 24 MPEG2: 23.98, 24, 29.97, 30  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

As of Dolby System 4.7.0...the CAT745 now supports 30fps. In fact, the current list for 4.7.0.42 is: System Frame Rates for DCP Playback DSS200 or DSS220 with CAT745 IMB JPEG 2000 4K 2D: 24, 25 JPEG 2000 2K 2D: 24, 25, 30, 48, 50, 60, 96, 100, 120 JPEG 2000 2K 3D: 24, 25, 30, 48, 50, 60 MPEG2: 23.98, 24, 25, 29.97, 30 DSS200 with CAT862 MB JPEG 2000 2K 2D: 24, 25, 30, 48, 50, 60 JPEG 2000 2K 3D: 24, 25, 30 MPEG2: 23.98, 24, 25, 29.97, 30, 47.95, 48, 50, 59.94, 60 DSS100 with DSP100 MB JPEG 2000 2D: 24, 48 JPEG 2000 3D: 24 MPEG2: 23.98, 24, 25, 29.97, 30, 47.95, 50, 60 If you download the current release notes from the DolbyCustomer portal (must have access rights), you'll get the current release notes. Dolby Secure is to be shut down and may no longer contain the most recent information anymore. Prior to 4.7, the CAT745 would not support 30fps. I have tested the CAT745 with 30fps on 4.7.0.42 and can confirm that it does work.  |  IP: Logged Antti Nayha Master Film Handler Posts: 268 From: Helsinki, Finland Registered: Oct 2008 posted 01-15-2014 07:42 AM                     Thanks Steve - that's great news! It's nice to have 30fps DCP support across the board, particularly for festivals that are creating some of their DCP's themselves from a vast variety of source material.  |  IP: Logged Jim Cassedy Phenomenal Film Handler Posts: 1661 From: San Francisco, CA Registered: Dec 2006 posted 01-15-2014 09:41 AM                     Thanks Antti & Steve! quote: Antti Nayha Which Dolby System version are you running? I'm working at another location across town for a couple of days, so I won't be back at that particular theater until this weekend. I'll take a look at the software versions, but I feel that the answer to my question is most likely in the table of info you posted. I was just curious since, as I said in my original post, so far I've only encountered this issue at only one theater, out of the dozens I've used this same 30fps DCP file at. I assume the "problem" is only limited to playing back DCP files, since DVD's, & blu-ray disks, as well as a satellite receiver, which I assume are outputting at 30fps work fine through the DVI-D inputs.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 01-15-2014 10:08 AM                     Jim, Yes, the CAT745, on initial release was rather limited in its frame rate capabilities. It looks like it now has the full compliment and had HDMI inputs active now too (2D only and at select resolutions). So any non-CAT745 theatres would not have had the issue. Any CAT745 theatres that are running on software below 4.7 would not handle 30fps. It was not a projector capability issue. You can check the individual projector manuals to see what their DVI capabilities are.  |  IP: Logged Jim Cassedy Phenomenal Film Handler Posts: 1661 From: San Francisco, CA Registered: Dec 2006 posted 01-20-2014 10:04 AM                     FOLLOW-UP: quote: Steve Guttag Prior to 4.7, the CAT745 would not support 30fps. I was at the location in question again on Saturday and took a print out of the charts you sent and you've nailed the problem. Their system is indeed running on older software. Vers 4.6.1 and Show Manager 4.6.3 on a DSS 220 & Cat 745. So that answers my question as to why 30fps DCP's wouldn't work a that location. Their system isn't that old- - it was installed last summer, but I beleive they got the equipment "second-hand", so it may have come loaded with the old software. Thanks again Steve & Antti!  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

It is a free upgrade to 4.7.0 for the DSS220/CAT745. I'd do it for numerous reasons.  |  IP: Logged
