Author Topic: Lost a show / Learned a lesson Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 02-16-2012 06:05 AM                     I believe Mike said that the normal "quick verify" didn't show any problems but using the more thorough verify DID show problems with the main OV file. Oh and Manny...I've never had a verify take as long as the load on a DSS200 (or 100)...in fact, they are normally not even close in length. The 1-hour also seems long, unless you are running a movie at the the time. It will load faster via CRU than USB though...USB will indeed take upwards of an hour or more, depending on the size of the movie.  |  IP: Logged Manny Knowles "What are these things and WHY are they BLUE???"

I've never ingested while also running a DCP. There just hasn't been a need to (yet). Perhaps the verify takes less time. I have yet to time that stage. I guesstimated based on how slow the progress bar was moving. It seemed to match the rate of ingestion.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

Right, that's what happened. About the verify time --- the quick verify on our server takes just a couple of seconds. The full verify, probably about 20 to 30 minutes for a typical movie.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 02-16-2012 08:06 PM                     Dolby does the full verify on each movie...since only the truly board will stare at the verify bar-graph as it crawls...it would seem to me that doing a full verify would go a long way to not having this sort of problem. That is, identifying the problem before the show so one might have a chance at replacing the content before it is needed. -Steve  |  IP: Logged Andrew Maddison Film Handler Posts: 13 From: Coventry, West Midlands, UK Registered: Sep 2007 posted 02-17-2012 04:17 AM                     quote: Geoff Newitt I'm also told they have a limit to the number of 'clips' they can keep track of - 1024 is the number that comes to mind; sounds like a lot, but in the UK we have extensive Ad reels, with each advert an individual CPL... One of our cinemas managed to have 1035 CPLs on one server through poor management of their content, and this definitely caused problems. Unless I've got the wrong end of the stick, would this only affect the people with Digital Cinema Media adverts rather than those from Pearl & Dean as P&D send out theirs as one large package and then a KDM which chooses the specific ads that are relevant to the screen?  |  IP: Logged Manny Knowles "What are these things and WHY are they BLUE???" Posts: 4247 From: Bloomington, IN, USA Registered: Feb 2002 posted 02-17-2012 07:12 AM                     Preliminary/intermediate experiment, since I don't have a feature to copy right now... I copied a 14GB short from the RAID to the backup drive (CRU). It took just under 5min. Would a 140GB feature take 10x as long as 14GB short? 30min? It seemed to take longer but maybe it's just that old adage at work: "a watched pot never boils." Would it take the same amount of going from the (CRU) backup drive to the RAID? Or is that a different process? (Repeating for convenience - I'm working with a Dolby DSS200) I'll be able to experiment more next week, or whenever I get another feature.  |  IP: Logged John Thomas Film Handler Posts: 75 From: Boston, MA Registered: Sep 2011 posted 02-17-2012 02:23 PM                     It's a bit faster going from the CRU drive back to the RAID. The bottleneck becomes the read speed of the single drive, which is faster than its write speed. If you were using USB for the same experiment it would be slower and the same speed both ways as the bottleneck would be USB's sad 480mbps transfer rate.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 02-23-2012 12:24 PM                     Brad, The files are copied to the RAID and THEN verified. The HASH key is then compared with the one listed in the packing list on the drive. Again, not familiar with GDC, but this is what Dolby/Doremi/XDC do. If the file is unreadable after is has ingested, it can only be a server failure - unlikely, since it's a RAID, I know. Andrew, The AdPacks you receive contain all the adverts individually - they are just not visible on the server (Sony actually show the individual CPLs). The file you receive is not a KDM, it's another CPL that defines the playlist for your theatre. To answer your question I'd say yes. But you just need to remove the older AdPacks and you should be on the safe side.  |  IP: Logged
