With the appropriate tool, also compiling a multi-reel CPL from existing single-reel CPLs should ne easy. For now, I would unwrap all the content to single images and wav files, concatenate/rename them into a single sequence, then recompile to a new DCP. Possible problem - the raw data of existing trailers from official sources often contains more material than the CPL plays - audio test tones, leftovers, etc, Concatenating the source media will make them visible and audible, if not skipped by the new CPL. The guys working on the open source software packages should be able to compile existing CPLs into a multi-reel CPL without too much effort. Maybe automatically adding a standard clip divider (1s black, no audio) in between. As far as I know, they are all working on multi-reel support anyway. - Carsten  |  IP: Logged Terrence Meiczinger Film Handler Posts: 45 From: Orono, Me, USA Registered: Dec 2008 posted 07-01-2011 08:05 AM                        If you are comfortable with a command line tool, OpenDCP will create multi-reel DCPs. You'd need to look at each individual CPL and get all of the MXF file picture/sound filename pairings. You could then pass each pairing as a separate reel into OpenDCP and it will create one multi-reel DCP. As Carsten points out you may get some ancillary video or audio because there are starting offset and duration values for each media piece.  |  IP: Logged Dominic Espinosa Phenomenal Film Handler Posts: 1172 From: California, U.S.A.

If there are a lot, this is a good time to use PERL and XML::Simple. Then run any of the open-source DCP tools to create a new CPL and PKL files. If this is a one-off kind of thing you could probably get away with copying/pasting the contents of the ReelList from each CPL into one CPL and then create a new PKL. The CPL doesn't have a hash of itself and the hashes of the essence files wont be changing. In this way you surely would preserve the EntryPoint and Duration information which is important. Theoretically it should work...  |  IP: Logged John Gavin Film Handler Posts: 12 From: Machida, Tokyo, Japan Registered: Nov 2010 posted 08-02-2011 01:50 AM                     Basically a new Packing list, Assetmap and CPL would have to be made. Since it is for advertising, non encrypted, you could try download a demo version of CineAsset as I think that can do it. The demo version is limited to 30s content duration, but you could at least see if it has the functionality. CineAsset The way i understand it would work is you import the MXF video and audio into the CineAsset database, then create a new CPL containing all the MXF files in the sequence you want them in. I will try to confirm 100% that CineAsset can do this and post here later.  |  IP: Logged
