[DCP-o-matic] issue with prores file (.mov) not automatically populating sound channels

by Billy Both

Hello, I love your program and works great with everything I’m doing for the Melbourne Film Festival that I’m presenting all the entries. The issue I’m having is a video that was sent in that is a ProRes/.mov video that is 7.1 sound is not automatically populating the sound channels for DCP-O-Matic. Can you help me with this issue?

Is there a file called "ffprobe.log" in your DCP-o-matic project folder?

Which version of DOM are you using? 16:9 is the same as 1.78. I knew the Content->'Scale to fit menu' would come over us at one time... ;-) These two options 'Scale to fit' are basically shortcuts to fill the screen in an easy way - but they usually cause cropping in an uncontrolled way. They should go under the list of other ScaleTo options, but for some reason at the time, there was no space there for it. It's been a while, but I remember no one was really happy with that solution. Normally, DCP-o-matic detects the aspect ratio of footage automatically, if it is flagged correctly, and if there is no letterboxed content. So, in your case, DOM did probably select 16:9/1.78, and then all you need to do is to confirm the flat container under DCP as far as scaling/aspect ratio goes. Some people say that 150MBit/s is enough. Yes, may be, but, the 'standard' spec goes up to 250MBit/s, and, with 30fps, you could need a bit more. Chances are high your footage doesn't need it, but as 16:9 is 'near' full frame, and at 30fps, just choose 200MBIt/s and then forget about that setting. If you're picky, use 235MBit/s, but don't try 250! Yes, you need to crunch through the full file again if you changed the data rate, as that concerns every single frame from the beginning. DCP-o-matic should start encoding from scratch when you change the datarate, but it also could be a point for a nice little bug (I doubt it). - Carsten

I assume you use 2.10.5? Under 'DCP' choose 'SMPTE' for Standard, container 'Flat' (1998*1080) and for framerate '30fps', 200MBit/s for data rate. Select your content in content list, then in the Content-> Video Tab -> Scale to: choose '1.78'. Reset all cropping values to 0 if there are any from previous experiments. You should see thin black bars left and right. Color conversion should automatically be set to rec709. In Prefs->General, you should have ticked 'Find integrated loudness, true peak and loudness range when analysing audio'. This will give you better numbers to estimate proper audio levels. Do you have a stereo or a surround/center based soundtrack? Peak values will only indicate wether there is clipping or not. As far as clipping goes, -2.6 is okay. However, this doesn't tell you wether your audio loudness is in the right ballpark for a cinema. Usually, this is not so critical for festivals, but, you should still try to be within the range that is common for cinema operations. Choose 'Audio'->Show graph of audio levels Do you have a listing of True Peak, Integrated loudness and loudness range on the bottom of that window? Tell us the value for 'Integrated loudness'. If there is no such value given, you probably performed the audio analysis before you ticked the advanded audio analysis in prefs. In that case, safe your project, exit DOM, got to the project folder, find and delete a folder 'analysis' within in. Restart DOM, reload your project, select 'Audio'->'Show graph of audio levels'. DOM should now take a bit longer to analyse the audio levels, and should show True Peak, Integrated loudness and loudness range. - Carsten

[DCP-o-matic] DCPomatic

by Joshua Achatz

Hi Carl, I am using the DCP-omatic to convert my film for a festival. I'm having a bit of trouble and hope you can help me. It was shot in 30fps, but the programs says that is an unusual frame rate. Should I change it to 24, and if so, do I just change it under the DCP tab? I want to make sure the video quality won't be compromised. But it sounds like it's okay to leave it at 30, from what I've heard. The program is also advising that I create an SMPTE DCP instead of an interop, because of the frame-rate. What is the difference? Should I do that? Also, under the DCP tab, I set the container to 16:9, but the program is saying if possible to put it in scope or flat, but those aren't the right size of my film, and leave those black edges on the sides of the picture. Please help me if you could. I've been working on this for a few days, and have to complete it soon for it to show in the festival. Thank you! Josh

Many thanks. > Audio analysis can take quite long, especially for full length features and on slower machines. If you are absolutely sure about your audio format and levels, you may disable audio analysis in prefs, so you can continue faster in DOM. You can always perform the analysis later when choosing 'Show audio' levels in content or DCP. Audio levels and channel mappings, however, are quite important for DCP playout in cinemas, so you should never give out a DCP without having done an analysis. Unlike most other codec-only formats/containers, a DCP is more complex and more parameters have to be set properly, so a 'one-click-conversion' does not make much sense. - Carsten

[DCP-o-matic] Very slow MacPro encoding

by Manuel AC

About 4 fps in a 12-core MacPro, configured with the default 24 threads. We have seen much better speeds in this same configuration. Tested with MKV and Prores sources, with some image modifications, and no modifications at all. Also tried on a network, with the MacPro as an encoding server and the laptop with the project not doing any JP2K encoding. Slightly lower speed as expected. The server log at the MacPro was giving about 5 seconds per frame, tha seems pretty high to me. I recently installed the latest test version 2.11.16, and trying to troubleshoot I tried with the also installed stable version from late December, with same speed result. Are OSX packages statically compiled? or installing the newer test version may have "damaged" some library shared with the older version? Anyone else have or had a similar problem? Thanks! Manuel AC

[DCP-o-matic] Rec709 vs BT1886 for DCP

by Todd Gilpin

Hi Carl, I have color graded a project in Resolve 12.5, color management is set to Rec.709 gamma 2.4, monitored the same on a Flanders. Taking it in to DCP-O-matic and I see the Rec.709 preset is locked at 2.2. If I change the gamma it changes the preset to BT1886. Is it safe to say this would be correct? I have seen debate as to whether BT1886 is the same as Rec709, but with a 2.4 gamma spec. I'm not an expert on this. Thanks in advance and thank you for the work you do on this software. Thanks Todd Gilpin Sent from my iPhone

However if I set it at 24 it plays on the projector fine – so problem solved! J It’s a bit unusual that this happens with a single file. Normally, even when doing 24->25 or 25->24 fps, DCP-o-matic should adjust both video and audio accordingly to match from beginning to end. If this happens again to you, it would be interesting to hear more details - file type, DOM version, maybe a copy of your metadata file. - Carsten

[DCP-o-matic] lol - Raspberry PI on new GDC IMB SR-1000

by Carsten Kurz

There had been some discussion on this list about using Raspberry PIs for DCP making and checking. Now, I just found a PI 3B sitting piggyback on the new GDC SR-1000 IMB: Raspberry PI 3B: https://cdn-reichelt.de/bilder/web/xxl_ws/A300/RASP_03_01.png <https://cdn-reichelt.de/bilder/web/xxl_ws/A300/RASP_03_01.png> GDC new SR-1000 IMB (IMS): http://www.gdc-tech.com/ndownload/product/SR1000/SR1000_front.jpg <http://www.gdc-tech.com/ndownload/product/SR1000/SR1000_front.jpg> They just removed the USB sockets. But it sure is a Raspberry PI 3B. It is probably the PI that earns this MB the 'standalone‘. No, the PI will not do the heavy (J2K) lifting et al., the MediaBlock itself is below the huge heat sink on the right side of the IMB. The PI will probably just do communications, webinterface/GUI. - Carsten

Re: [DCP-o-matic] DCP issue

by Carsten Kurz

Hi John, approx one minute in 30min sounds like a 24/25fps issue. That IS usually no issue, you are free to generate a DCP with either 24 or 25 fps in both SMPTE or INTEROP format - except if you operate a Dolby DSS100/DSP100, which is not able to play 25fps. There are still quite a few DSS100/DSP100 around, so if there is a chance your DCP might end up on one of those, you should also create a 24fps version. This should not occur with a single (interleaved video/audio) file of content, so I assume you use more than one content file? - Carsten > Am 31.07.2017 um 08:00 schrieb John Martin <John(a)trinitytheatre.net>: > > Hi Carsten, > > Thank you for coming back so quickly – the answer appears to be framerate – the software was prompting me to change it – but if I ignore that it remains the same length. > > I will test it when I am in the theatre today. > > Thanks again. > > Best regards > > John Martin > Artistic Director > > Phone: 07762 587768 > Website: www.trinitytheatre.net <http://www.trinitytheatre.net/> > Get more info at: <image001.png> <http://www.facebook.com/trinitytheatre/TRINITY-SRV01/Users/darren.smallman/…> <image002.png> <http://www.linkedin.com/company/trinity-theatre> <image003.png> <http://twitter.com/trinitytheatre> > > From: Carsten Kurz [mailto:audiovisual@t-online.de <mailto:audiovisual@t-online.de>] > Sent: 30 July 2017 14:19 > To: John Martin; dcpomatic(a)carlh.net <mailto:dcpomatic@carlh.net> > Subject: Re: [DCP-o-matic] DCP issue > > Open timeline view and check wether there is an overlapping/longer audio track, or subtitles.

[DCP-o-matic] Little help need → dvd to dcp

by Gérald Maruccia

Hi… …not the first time I do that but today I fail… DCP-O-Matic 2.10.5 git 61b5d4ad8 on Ubuntu 14.04. I have a dvd to convert to dcp. First thing I did was concatenate the 4 vob into one file : cat VTS_01_1.VOB VTS_01_2.VOB VTS_01_3.VOB VTS_01_4.VOB | ffmpeg -i - brialy.mp4 Then I use some personal script to get some kind of 5.1 sound → file becomes brialy_51.mov Now in DCP-o-Matic conversion always stops @ same number of images ( about 4500 ). There's some warning in log @ line 2407 FFmpeg: Warning: data is not aligned! This can lead to a speedloss Files attached are log, ffprobe.log andmy script for 5.1 upmix. I suspect more has to be done regarding « concatenate » the vob into one single. Any hints / help welcome. Best regards, Gerald

[DCP-o-matic] Dolby TruHD audio analyze

by Jonathan K. F. Jensen

Hi all. Every now I get a BD that needs to be converted to DCP, usually because the content isn't out on DCP or it's a pre-release for a special screening of some sorts. This time the BD content actually has a Dolby TrueHD 7.1 track, which is the obvious choice, as the screening is in a 7.1 room. As I usually do, I create a mkv file with subtitles and the desired track by using MakeMKV. DOM sees both the subtitle track and the 7.1 audio track which I can then map accordingly when I set ''12 - 7.1/HI/VI However, when clicking the 'analyze audio' button, everything comes to a halt. After churning for 3 hours, the ETA was 273 hours! :D That is somewhat excessive and I am thinking there might be a bug somewhere, as I can see Carsten and others have mentioned in the forums (DOM and Film-Tech) that they successfully have used Dolby TrueHD tracks in their DCPs. I'd rather not waste the time encoding the DCP if the levels are too high, so maybe someone can comment on this behavior? DOM v2.10.5 Win10 Pro Best regards, Jonathan
