Author Topic: Create/convert to DCP Kris Verhanneman Expert Film Handler Posts: 182 From: Belgium Registered: Dec 2009 posted 02-22-2013 11:00 AM                     Maybe I didn't express myself correctly... (would not be a first time). I would like to be able to take a non crypted dcp trialer/commercial and convert it back to something that can be read on a standart pc. I don't mind that it takes some time.  |  IP: Logged Aleksandar Obradovic Expert Film Handler Posts: 125 From: Belgrade, Serbia Registered: Oct 2012 posted 02-22-2013 11:36 AM                     There is no need for conversion because VLC can play some of MXF files. Otherwise you should buy some piece of software which can convert it. AFAIK there is no open source converter for such stuff.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 02-22-2013 11:41 AM                     true - 'some MXF files' ... ;-) Kris - you will have to wait some time, imperfect solutions are there, more are coming. Transcoding is possible with open source software, but not strictly GUI based. It takes some time and is not suitable for just checking/viewing content on the fly. If you can spend some money, get dcpPlayer for around 250US$ and run it on a decent machine. It will not just play the MXF Files, but the full composition. - Carsten  |  IP: Logged Aleksandar Obradovic Expert Film Handler Posts: 125 From: Belgrade, Serbia Registered: Oct 2012 posted 02-22-2013 11:53 AM                     @Carsten Mate do you know why i have green overlay when playing some mxf's in VLC? Colorspace problem maybe?  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 02-22-2013 12:05 PM                     They are working on it. Only VLC 2.02 and 2.03 can play J2C, it's broken again in 2.04 and 2.05. But they are working on a much better decoder for the 2.1 release. Issue is XYZ 12Bit colour in J2c codestream. Of course it works with MPEG-2 interop files. - Carsten  |  IP: Logged Kris Verhanneman Expert Film Handler Posts: 182 From: Belgium Registered: Dec 2009 posted 02-22-2013 01:41 PM                     okay it would be nice to be able to edit the trailers on a pc  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 02-22-2013 01:46 PM                     Editing - in how far? After unwrapping, you can load the single image sequence + associated audio into the usual breed of video editors. Edit - but then you have to recode the J2C with the known free tools and compile it into a new DCP. Possible, but not straightforward with current tools. There are some quirks in using the MXFs without the CPL - namely, lead-in/lead-out, beeps, etc, Nothing really complicated, but the MXFs are not a 1:1 representation of the trailer as it is played on the server. - Carsten  |  IP: Logged Wolfgang Woehl Film Handler Posts: 31 From: Munich, Germany Registered: Apr 2012 posted 02-22-2013 04:41 PM                        Carsten, there are a bunch of applications. Be aware that in some (not small) markets distribution DCPs are the master source for localization -- there is no access to an actual master. The proxy tool was initially written for a client who needs to spot and add subtitles for his market. Then there is the issue of censor cuts which they locate via proxy, generate EDLs and apply to compositions. It's not a testing tool, mind you  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 02-23-2013 09:10 AM                     Any non-commercial/-expensive options? Not that I know of. As long as one is working/doing edits on the J2C file level, no re-encoding would be necessary. - Carsten  |  IP: Logged Grant Chambers Film Handler Posts: 29 From: Branson Missouri, USA Registered: Jul 2012 posted 02-23-2013 10:26 PM                     Hmm. Interesting. I've been using Open DCP. The sound issues could be from a wrong bit depth (24bit WAV mono/ channel) Not sure. All I know is with open dcp, I do the following: Convert my media to the right resolution (crop/resize) 2K or 4k depending. Scope or Flat. Create a 16bit per channel tiff sequence in Adobe After Effects. Use open dcp to convert the tiff files to Jpeg2000 sequence. Create MXF from the Jpeg sequence Create MXF from the Audio (24bit WAV per channel. I use Adobe audition to split stereo to 5.1 surround sound and tweek it if needed, then convert channels to mono WAV files. Open DCP also does 3D very well. I've been getting some pretty nice Stereo 3D on my Dolby Server. Still learning though.  |  IP: Logged Carl Hetherington Film Handler Posts: 93 From: York, North Yorkshire, England Registered: Jul 2012 posted 03-05-2013 09:11 AM                        Talking about audio levels when making DCPs... quote: Carl Hetherington You can fix it by going to the Audio tab of DVD-o-matic and changing the value for "audio gain". A negative value will make it quieter. If it is way too loud you might start with -12dB and see how that sounds; you will need to recreate the DCP afterwards but it should be fairly quick as it will re-use the video encoded for the previous run. As for knowing to do that; as others have suggested, you can only really do it by playing back the source file and referencing it to others. There should be a way of getting DVD-o-matic to give some indication of the source audio level, but it might be hard to get a representation that is useful. I have added a primitive plotting feature to DVD-o-matic 0.76 which displays a graph of sound level (peak / RMS) in the source. It might help out with this problem, a bit ... but I suppose it will need to be tried out in real life to see if it is any use.

What cinema are you working for ???  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 04-12-2013 09:55 AM                     The recent versions of DVD-o-matic have some nice improvements. I start to like this piece of software ;-), especially since it omits the enormously storage intensive single-image input/intermediate approach of most other DCP creating software, and, for an all-in-one-converter, all processing options are easy to use, well documented and make sense. It is NOT a competitor to OpenDCP, DCPC, DCPBuilder, etc., but a nice completion of options. It lacks, 3D, 4k, 7.1, but it shines at conversions and ease of use. There also is a manual ;-) Currently, it is available for Windows and Linux. Now, Carl Hetherington has set up an Indiegogo Kickstarter-like project to enable a MacPort. As such he needs the minimum investment into a Mac - a MacMini for porting and testing. Please support his effort!
