Carl, have you thought about how multi-version capability could be implemented into DCP-o-matic? I understand that currently for most people it only makes sense for timed-text which is only in 2.x, but I guess one could still think about ways how to implement it? - Carsten

[DCP-o-matic] Mac OS X legacy support

by Carsten Kurz

I remember a thread in the forum where one guy was running dcp-o-matic on a G5 PowerMac. I was surprised it actually seemed to run on a PPC. Does anyone know exactly which OSs are still supported? A friend just wanted to test-drive it on his video-editing G5 running Tiger/10.4, but it didn't start. Same result on an Intel iMac running 10.5.8. The lowest OS X version I do usually test is 10.6.8. I think the guy on the support forum mentions 10.7 on a G5. I always thought 10.5.8 was the latest OS X version supporting PPC? - Carsten

[DCP-o-matic] DCP playback

by Andrew Levine

Hi there, I am new to DCP's and this list,–very likely like many others before–having been thrust into this world by the need to deliver a film to a movie theater in their preferred format. Above all my monster is a little over two hours long, with a 5.1 soundtrack ;-) Being a Mac person (up to this point…) I got a trial version of a commercial player to test DCP playback. Waiting for my refurbished renering machine that can run Windows I also signed up for digitAll dcpPlayerFree, but what I realised is that I would not need so much functionality for peace of mind. Would it be possible to create a free DCP-player that read a buffer of like say 5-10 sec worth of images and sound, generated a temporary movie file for playback using a local architecture, like QuickTime on the Mac, and then played the segment? The user would use the slider to determine where to start. The great advantage would be that one could check the file from within DCP-o-matic, including encrypted media, which is a function reserved for the pricy commercial players. Cheers, Andrew

[DCP-o-matic] Render-times

by Andrew Levine

Hi there, I got a Dell Precision T5500 (with 24 GB of memory; it seems I really need about 8) yesterday, and after organising a Displayport-cable today was able to run a first test, writing to an external USB-2 disk: 10.002 frames iMac (I7-4771 3,5 GHz - Passmark 9940) Tue Feb 24 17:15:44 2015: Job: Encoding image data … Tue Feb 24 17:59:50 2015: Mopping up 0 44:06 (2646 sec) 3,8 fps Tue Feb 24 18:03:36 2015: Transcode job completed successfully 04:46 Dell (2 x X5650 2.7 GHz - Passmark 7584, Dual 11695) [Windows 7] Wed Feb 25 15:00:12 2015: Job: Encoding image data … Wed Feb 25 15:27:07 2015: Mopping up 0 26:55 (1615 sec) 6,2 fps Wed Feb 25 15:30:15 2015: Transcode job completed successfully 03:08 Dell + imac as background render node Wed Feb 25 16:00:23 2015: Job: Encoding image data … Wed Feb 25 16:18:12 2015: Mopping up 0 17:49 (1069 sec) 9,3 fps Wed Feb 25 16:20:35 2015: Transcode job completed successfully 02:23 Would it be better to run a Linux on it? Will using the eSata connection for the external HD make much of a difference? Regards, Andrew

Hi all, There have been some problems lately with this mailing list bouncing when sending email to @yahoo addresses. I've just installed a Mailman update which will hopefully fix it. If someone with an @yahoo.com address reads this, perhaps they could post a short reply to test it out. Thanks & sorry for the noise. Best regards, Carl

The original reasoning was to spot if the end of a previous encode had been corrupted by a crash / power-cut or whatever. On reflection it seems more sensible perhaps to work back from the end of the existing data and find the first frame that has the correct checksum, then continue the encode from there.

Re: [DCP-o-matic] Sound Sync

by Kevin Orman

Hi Carl, Re: Sound Sync. I'm using 1.76 which I've just realised is not the latest.. in the timing tab I changed frame rate from 25 to 24 and I believe DCP-o-Matic used to say, audio re-sampled to xxx, but it does not now so I must be changing the wrong value. Any ideas? Thanks, Kevin.

[DCP-o-matic] Sound Sync

by Kevin Orman

I'm having an issue with sound sync. Input file is an AVI at 25fps and I set DCP-o-Matic to output 24fps (our projector can handle 25fps ok but there is a visual glitch when the frame-rate changes). The problem is that although the image does run at 24fps the audio continues at 25fps which obviously causes it to be wildly out of sync. Am I doing something wrong? Kevin Orman

[DCP-o-matic] Process Details

by Carsten Kurz

I mentioned before that I like the way DCP-o-matic shows the essential processing options below the content tab, so that there is a quick overview about what happens during the conversion with regard to scaling, aspect ratio, audio, etc. Wondering wether we could add a full set of these details below the DCP tab - as there is more than enough space there, and some of the DCP tab options are relevant to these. Also, the DCP tab should normally be the final stage before one hits 'Jobs -> Create DCP', so I think it would be good to have an overview over all essential processing there before one finally hits 'Make DCP. One could even an another 'Make DCP' button there. In a later release, I also think it would be more useful to include the 'tips' or hints there, possibly behind the specific parameter causing the warning/hint. I think 'Tips' will be easily missed as it has to be called manually. e.g. something like: Content frame rate is 25 fps -> Warning Icon, Click and 'Your DCP frame rate 25fps may cause problems...' appears. Same for audio issues, DCP bandwith, etc. This would add to my idea from above for a full overview of most essential aspects of the DCP creation. And: I brought this up earlier, but Carl has a different opinion on this: I still think the scaling method should go under the content tab and has to be settable content-specific. I don't think it makes sense to have a choice of different scaling methods, but only 'global'. The only reason to choose different scaling methods should be content-related. Another reason: Scaling method is not a DCI/DCP specific parameter, unlike all other parameters under the DCP tab. - Carsten

Re: [DCP-o-matic] HFR 50fps

'Classic' server-side media blocks with HD-SDI connections towards the projector use a different transmission colorspace for 3D (because Dual-Link HD-SDI can not do 48fps in full 12Bit xyz/4:4:4). Thus for 3D, these systems use 10Bit YCbCr over HD-SDI between Server and projector, so the projector needs a special input format for 3D. But HFR in the strict sense of HFR-3D does not work on these systems anyway, HFR-3D (96/120Hz playout frame rate) does not work over HD-SDI at all. Only IMB/IMS Systems support HFR-3D, and the IMB systems does not suffer the bandwith limitation as HD-SDI, so, 3D on IMB systems use xyz/4:4:4 as well as 2D/24fps. But for all those formats and signals, the storage/DCP format is always yxz. And that is what DCP-o-matic does. You may in fact be after playing 48fps 2D, so to say, 2D-HFR. And you may have found an 48fps YCbCr format on the projector. But that is meant to be used with 'classic' 3D on HD-SDI systems. Technweise, the DCP storage format is always xyz, not matter what frame rate or 2D/3D. The transmission format between server and mediablock/projector can ALWAYS be different, but that is nothing DCP-o-matic has to deal with. You configure suitable output/input formats on server and projector to deal with that. - Carsten

[DCP-o-matic] Strange localization issue

by Carsten Kurz

A dcp-o-matic user sent me a screenshot to get some advice on proper scaling options for his project. I noticed that the german localization on his machine is screwed - his screenshot shows english and german mixed wildly. Any idea what could cause this? He is using Mavericks (OS X 10.10.1). Occurs with both 1.76 and 1.76.42. Second screenshot is 10.6.8 - everything okay. Did anyone else have similiar issues with other localizations in OS X versions? Carl - I noticed dramatically different file sizes in the various versions of DCP-o-matic for Mac - e.g. sometimes 25Mbytes, sometimes 120MBytes. The current breed is rather small. What's the reason for that? - Carsten

[DCP-o-matic] DCP-o-matic 1.77.0 released

by Carl Hetherington

Hi all, DCP-o-matic 1.77.0 is now available from: http://dcpomatic.com/download This version includes: A full 36-bit (12 bit-per-channel) colour path through DCP-o-matic when high depth sources are used. Updated fr_FR translation from Thierry Journet and Lilian Lefranc. Updated de_DE translation from Carsten Kurz. Fix for slipping audio sync on DTS-encoded audio tracks in some cases (#352). Fix for incorrect read of some video files from iTunes (where they come up as being at 90,000 fps). Fix for parts of content at presentation times less than zero being played in certain circumstances (#418). Fix incorrect behaviour of "Down" button (to move content later in the list). Fix snap on the timeline to work properly when butting bits of content up to each other. Fix for long hangs at 99% complete when encoding files with large trims. Fix for a crash when dragging things in the timeline (and possibly at other times). Fix for incorrect subtitle timing when sources are trimmed. Fix for crash at 99% encoded in some cases. Fix for over-sensitive error checking in some cases. Fix problems with downloading projector certificates on Windows (#442). Make a considerable number of crashes give more useful error messages. Display sample aspect ratio for video content that declares it. Stop Cancel in the Add Cinema dialogue creating a new (empty-named) cinema (#449). Add ‘Copy as name’ button to copy the ISDCF name to the editable field in the DCP tab rather than the hack which copied it when ‘Use ISDCF name’ was un-ticked. Remove default scale configuration option and instead guess the initial scale from the content's size and pixel aspect ratio. Allow bypass of digest calculation for image sequence content. Allow bypass of colourspace conversion (#266) Rename “Add folder” button to “Add image sequence” Move “Keep video in sequence” button into the timeline window. Add Pause button for all jobs (part of #344) Remove code to load old DVD-o-matic configurations, as it's not well tested. Speculative fix for hangs at the end of encodes when using 3D content. Increase maximum allowed JPEG2000 bandwidth. Thanks to Mike Blakesley, Carsten Kurz, David Nedrow, Thierry Journet, Mark Rolfe, Lilian Lefranc, Manuel AC and Elad Saad.

[DCP-o-matic] Trimming/Audio

by Carsten Kurz

Someone told me about his problem with trimming off the end of files. He usually does that based on the visuals (as in 'in fabulous 3D'). However, he can't hear the audio in DCP-o-matic, and his trims very often cuts of audio. Could there be a way to solve this in DCP-o-matic? Is it very difficult to add audio monitoring to the preview function? Or splitting audio/video that has been imported interleaved? - Carsten

[DCP-o-matic] testing a TKR server

by Manuel AC

I started making a very basic TKR server, but I'm not used to work with KDMs and all that signature thingy madness. Can someone create a small test DCP? I was tempted to modify the dcpomatic code myself, but compiling it in my own! has been too long without doing that stuff :) Should try, indeed. I know it can be done manually adding the TKR line to the CPL, correcting the hashes and then signing with cinemaslides. I can do a test in a few days in a few servers with internet access (Doremi 253522, 253523, 253524) At my usual theater I'm still trying to figure out how to give the servers connection properly, I don't control all the network.

[DCP-o-matic] anamorphic video

by Carsten Kurz

Hi Carl, I have received a video in AVI container, DV codec, so, pretty standard. However, it is anamorphic, so no square pixels. Various media players on my machine detect it properly as 16:9, but DCP-o-matic 1.76.7 detects it as 720x576 (1.25:1) and squeezes it when choosing 'no scale'. No big deal to correct this manually in the scaling options, but maybe you can fix that. Since the media players display it correctly, there must be a flag the DCP-o-matic currently ignores when analyzing it. The same happens when importing 16:9 VOBs from e.g. DVDs. Hmm, I understand that there is some interpretation necessary. DCP-o-matic first follows Default Scale To in prefs. While that is correct, and some options chosen have to result in wrong aspect ratio scaling, I think that at least the 'no scale/no stretch' options should follow the original content AR, if it is clearly indicated in the file metadata. At least the content description should indicate that the files is flagged 16:9/anamorphic. Aside from what the fact that in this case I can create a proper upscaled video - there is no way I could create an unscaled version of this file with the correct aspect ratio. When I choose 16:9, it get's uprezz'd, when I choose unscaled, I get a square 720/576 in a flat frame, when I choose NoStretch, I get a square 1350x1080. There is no way I can assign a 16:9 reference to this file. I think the proper way to handle this is to find a 16:9/non-square pixel flag in the file and act accordingly, that is, display it stretched and with a 16:9/anamorphic indication. I think that fight for all necessary yet straightfordward arranging of scaling options will never end... - Carsten

[DCP-o-matic] audio subsampling when adjusting frame rate

by Carsten Kurz

I just did a test with separate video/audio clips. Imported them, video source is 24fps. DCP-o-matic reports source and DCP will have same frame rate. No mention of audio. I then adjust the DCP frame rate to 25 fps. DCP-o-matic tells me that the frame rate will be adjusted to 25 fps. However, there is no indication what it will now do anything with the audio? I think we discussed this before shortly, but didn't come to a proper conclusion. With separate audio files, will DCP-o-matic simply assume that the separate audio has to be in sync to the chosen DCP frame rate? Because with a different frame rate for video, it could just as well resample the audio to 25 fps as well - but it needs to be instructed to do so - which includes that there is a frame rate/sampling rate relation established before and a change being notified. The question is - with separate audio, how/where do you establish it's frame rate reference at first so that DCP-o-matic knows to what framerate the audio is referenced? With interleaved audio, this is clear, upon loading it, the audio/video timing reference is established, but with separate video and audio files? Did I make my issue clear? - Carsten

[DCP-o-matic] Strange colour conversion problem

Hi all, I have a user who is reporting that he has a content file graded to Rec. 709, which he is converting to DCP using DCP-o-matic's Rec. 709 preset. He reports that on a projector he sees pinker skin tones, and the entire image seems a little desaturated. He also tests on Easy DCP player and gets the following results with its various colour conversions: XYZ to RGB (P3): exactly as seen in the cinema (pinker skin tones, desaturated) XYZ to RGB (Rec 709): looks as it should I'm a bit confused... does anyone have any idea what might be going on?

[DCP-o-matic] How many encoding servers?

by Jim Dummett

Hello all. I'm doing tech on the London Short Film Festival which is January. We are delivering all the films to cinemas on DCP this year (all 350 of them) and will be using DCP-o-matic to use them. We're holding a workshop tomorrow and Sunday where we're going to train 100 film-makers on DCP-o-matic, and then guide them through the process so that by the end of the weekend, they will hopefully all have DCPs of their films. I have a couple of last-minute questions that I would very much appreciate it if anyone would be able to help with. _1. Encoding servers_ We have a network of 30 iMacs, all networked together with Gigabit ethernet. We intend to run dcpomatic_server_cli on all of those, with DCP-o-matic itself running on the laptops of the film-makers and using the encoding servers to do the heavy lifting. a. Will it work with 30 encoding servers? b. What happens if two instances of DCP-o-matic try to send jobs to the encoding servers simultaneously? Is it first-come-first-served and whoever submits their job first gets control of all the encoding servers until their job is complete? Or do the encoding servers get shared out between different jobs so multiple jobs can run concurrently? Or, terror-of-terrors, will the whole thing crash? _2. Best version to use_ How stable is v1.76.13 likely to be? Or should we use v1.76.0? I've been told that some issues with colour space conversion are being resolved in recent test releases. Is v1.76.13 going to give a better result in terms of colour than the 1.76stable? Sorry for the barrage of last-minute queries. I hope someone may have some pointers? Many thanks, Jim

The film is currently a DPX sequence in Resolve that was rendered in P3 colour space already.

If I export TIFFs from Resolve with an XYZ LUT applied, the DCP program will end up doing it again - so that’s XYZ conversion done TWICE, which I want to avoid.

[DCP-o-matic] 'Show DCP' menu entry

by Carsten Kurz

I guess the intention of the 'Show DCP' menu entry under 'Jobs' ist to show the path/directory of the currently generated DCP? I think this never worked in the Mac version, or did it? Currently, it does nothing. A lot of unexperienced users ask which of the various files and directories DCP-o-matic creates should be copied to the transfer drive. While this is essentially a training/knowledge problem, I think choosing 'Show DCP' should result in the display of the parent folder of the DCP directory, with the DCP folder selected/highlighted so it can be easily identified. It nearly works in the windows version ;-) - Carsten

[DCP-o-matic] DCP without sound

by Carsten Kurz

Today I had to create a DCP without sound, that is, the minimum requirement would be 2ch, padded with silence. I think DCP-o-matic has no formal way to do this - I can set channel count to 0 in DCP properties, but then I get a warning that my DCP contains no sound, that I guess means that no audio.mxf will be generated at all. Same happens when I deselect the existing two audio channels in content audio tab. I think DCP-o.matic should be stricter, that is, if channel count is set to 0, it should create a 2-channel file padded with silence. Same if I deselect existing channels in an interleaved video/audio file. And it should force channel count to an even number of channels any time. Maybe for now, the easiest way is to limit the channel choices in the DCP tab to 2,4,6,8..., and if there is no audio, or it is deselected in the audio matrix, it should padd the channels chosen in DCP tab with silence. Of couse, I could just use a very high negative gain, or map the existing audio to channels typically not used. But I think there should be a straighter way. - Carsten

[DCP-o-matic] single image slide/sequence

by Carsten Kurz

Hi Carl, I recently received a few questions from users which wanted to import image sequences for video. I had to pinpoint them towards the fact that you can select multiple images with 'Add file' as well as with 'Add directory'. They didn't understand that by using 'Add file', the images would be interpreted as single objects, creating a sequence of slides, and by using 'add directory', they would be interpreted as an image sequence for moving image. I would like to make this more clear in the naming/translation of the 'add directory' - however - which consequence will it have when using 'add directory' with other media types, can you tell us which interpretation is behind that option in contrast to add file with a multi-file selection? Because if it only works with image sequences for video, we could just as well name it that way. - Carsten

[DCP-o-matic] Oddity with iTunes files

by David Nedrow

Someone I know had a problem when trying to convert an iTunes music video file using DCP-o-matic. When adding the file, the summary shows a content frame rate of 90000.0000, that every other frame will be used, and the DCP will run at 0.133333% of the content speed. The timing tab shows a play length of over 38 hours (this is a 3 minute music video) and a video frame rate of 90000.0000. I was able to duplicate this in 1.76 and 1.76.2 with an iTunes music video I have. These files are not DRMd. Any suggestions as to what may be the problem? -David

[DCP-o-matic] P3 to XYZ conversion matrix

by Carl Hetherington

Here's a question for the list! :) Any suggestions, anyone? ---------- Forwarded message ---------- Date: Tue, 14 Oct 2014 16:16:10 +0100 From: Anand Madabushi <armadabushi(a)gmail.com> To: carl(a)dcpomatic.com Subject: P3 to XYZ conversion matrix Hi Carl, I've got a feature film that's currently sitting in DCI-P3 colour space. I'd like to use a custom matrix to convert this space to XYZ using your awesome software. You currently have 3 presets, but not a P3 one. I've scoured the web trying to find a 3x3 matrix to do this conversion and even tried to calculate one mathematically - with no success. I would assume others have tried to do something similar. Any idea where I can find a conversion matrix for P3 to XYZ? Many thanks, Anand Madabushi Outsight Films, London

Re: [DCP-o-matic] Signed or not

by Sumit Guha

I recently had to correct the hash value on one of the reels of an Interop DCP, which was also signed. I changed the hash values of the reel in the cpl and pkl files and also had to change the hash value of the modified cpl asset in the pkl. I was lucky to be able to test this on a few different systems: 1. Christie IMB 2. Dolby IMB 3. Doremi DCP 2K4 4. Doremi IMB All 4 systems ingested the content successfully. Apart from the Christie IMB, the remaining three systems had no issues playing back the modified DCP. The Christie IMB came up with a 'CPL Validation Issue' when I tried to play it.

[DCP-o-matic] Color Space Rec 709 or sRGB

by Andreas Eli

Hello! I think this question has been asked before, but I am still not comfortable with it. I understand the difference between these two color spaces, but how do I know what to choose when working with DCP o Matic? How can I check the color space of a video file? And what do I do if I do not know it? When working with HD Material, is Rec 709 the common color space? When I export from Premiere to Avi uncompressed, TIFF sequence or H264, how do I know what the color space is? Any answer is appreciated! Thanks Andi

[DCP-o-matic] Encoding servers and LAN

by fred.bobigny＠laposte.net

Hi all, I was wondering how encoding servers are detected by main dcp-o-matic instance. I've noticed that all machines should be on the same local network, but does this mean L2 connected or L3 is Ok? I.e: does main instance scan all IPs included in its subnet or detecting MAC adresses thru ARP? Thanks for this precision, Fred http://www.etheractis.fr/

[DCP-o-matic] Network bandwidth needs, and also revisiting a (possibly) pointless discussion

by Leslie Hartmier

Hey everyone! I have a question regarding the conversion farms that people have made, and I would like some insight. We're going to have some fun creating a four octo-core machine farm to make DCPs out of whatever comes our way, and I was wondering if anyone is using 10GbE for their internal network. Clearly, 10,000 Base-T is not really necessary for most things. However, we would like to make sure that the bottleneck is not the network, but I also don't want to have to special order about $3,000 in 10GbE hardware to do this if it is not necessary, so if a 1GbE network is comfortably adequate for the process, I really would look forward to that kind of assurance. It would cut the current tally back about a third on the build. On the other hand, if it would be a major benefit, I don't want to take it off the table either. Now onto the other thing: NOTE: I'm certainly not pushing. I was wondering if DCP-o-matic using GPUs for conversion is closer to the front of the minds of Carl and the others. The reason for this is that I don't intend to buy the video cards for the subordinate servers as, if the software is not going to do this any time soon, using the onboard video will be fine, especially since the machines won't even have monitors, keyboards or mice (we'll use TeamViewer to access the machines if need be). I remember the discussion where optimistic thoughts were bandied about for a golden future where everything was always exactly the way we wanted it, so I just thought I'd ask. I mean, the subs will be using linux, and only the master will run Windows (put simply, there are people who are a bit strident regarding the ease for which they expect to use the system, and hey, a single license of Windows is not the expensive part of the build.) Thanks! Leslie

[DCP-o-matic] Reusing DCPs in DCP-o-matic

by Carsten Kurz

I just did a test loading the video part of a DCP into DCP-o-matic and trying different scaling options. It actually works quite good and it seems that the FFMPEG input also chooses the right colour model (no doubled xyz), so technically, it seems to be no problem to run a DCP through DCP-o-matic for cropping, trimming, dubbing, etc. Just that DCP-o-matic currently will not read an audio MXF as an audio file but fails trying to read it as a video file. Carl, do you think this audio detection issue could be solved somehow? Most people would find it weird running a DCP through the program, but as DCPs currently are not easily editable and good/free converters are not available, it could still be a useful workflow to do simple edits. I know you can always try to feed the audio externally after unwrapping, but it would be far more easy if DCP-o-matic could do it. - Carsten

[DCP-o-matic] DCP-o-matic version 2

by Carl Hetherington

Hi all, I have been working on a new branch of DCP-o-matic, whose version numbers start with 2 (e.g. the current version is 2.0.5). The main new features of this branch are: - import of existing DCPs, allowing re-packing, trimming etc. - import of .SRT format subtitles - creation of DCPs with "proper" (XML) subtitles However there has been a fair bit of rearrangement of the code, so there are almost certainly new bugs with old features (as well as new bugs with new features!) I would not advise anyone to use version 2.0.x for "production". Having said that, if anyone wants to try, it would be great to hear how you get on. You can get the current version from here: http://dcpomatic.com/v2 Version 2.0.x will install alongside your existing DCP-o-matic install, and I'll still be working on the 1.x branch for the forseeable future. If you have any bug reports etc. please feel free to email me or the list, or add them directly to the bug tracker here: http://carlh.net/mantis Best regards Carl

[DCP-o-matic] Crash when quitting while in preferences

by Carsten Kurz

It happens regularly in the Mac version (also earlier than the current one) - quitting the program (CMD+Q) while being in preferences, will always crash the application. No big deal, but maybe easy to fix. Also, there seems to be a problem with the audio analysis in the mac version, when you reopen a previously save project - the program seems to assume that an audio analysis has been already performed, but is missing the analysis data. Hence, there is no volume graph. Only solution is to discard the content audio and reloading it - then an analysis will be performed and the graph is there. This also happened in most earlier mac versions I tried this. The current windows version does not have that issue. - Carsten

Hi all, I just uploaded DCP-o-matic 1.73.0. This version includes: Fix for unexpectedly lost bits of content (10 minutes from the end of files, for example) Updated de_DE translation from Carsten Kurz. Updated fr_FR translation from Grégoire Ausina. Fix buggy trimming of content when overriding its detected frame rate. Fix various strange behaviours with translation of the KDM email in preferences. Fix missing translations of some UI parts. Fix to fetching of Doremi certificates with imb- filename prefixes. Hopefully fix random crashes (especially during encoding) on certain versions of OS X. The optional <Hash> tags are now written to CPL files to try and make Technicolor happy. A new ‘default scaling’ option in preferences. Allow changing of timing properties for many pieces of content at the same time. Add KDM email BCC option. Special thanks to Carsten Kurz, Grégoire Ausina, Will Meadows and Jamie Rokovetsky. Download it from: http://dcpomatic.com/download Any comments, bug reports etc. are welcome to the mailing list (dcpomatic(a)carlh.net) or me personally (carl(a)dcpomatic.com).

[DCP-o-matic] DCPomatic

by Steffen Hager

Hallo, I've been using for a long time, the program for creating DCPs for a small cinema in Leipzig and am very satisfied. However, recently I noticed with version 1.72 a bug: I want to create two longer DCPs to each 117 and 104 minutes. After the upload of each file (m2ts) and their content check, the software takes only about 117 107 and 104 instead showed only about 93 minutes. In fact, I've noticed in the preview monitor, that in each case the last 10 minutes of the films were missing. I then installed and found that the error occurs from version 1.70 or older. For a short feedback I would be grateful. best regards Steffen Hager --- Diese E-Mail ist frei von Viren und Malware, denn der avast! Antivirus Schutz ist aktiv. http://www.avast.com

[DCP-o-matic] Trimming issues

by Ben Edwards

So I set it up so it would start 5 minutes in and encode 15 minutes. What I got was a DCP the length of the full film, with audio starting at the beginning and ending at the end (i.e no trimming), however the video starts from 5 minutes in and goes for 15 mins (i.e. trimming worked). It has done the trimming as asked for image but not audio. This means the audio is massively out of sync, by 5 minutes. The good new is my audio problem seems to be sorted and it looks great (think the gamma was 2.2).

[DCP-o-matic] Tested first mayor DCP, few issues

by Ben Edwards

So I managed to create a DCP of the first 30 mins of the feature I am DCPing and get it on a ext3 drive. Ingested and plays fine but there are a few problems. Firstly the audio is pooping in some places, We have a Dolby CP750 and setting it between 3.5-4 seems about right for this DCP. This is very low so I guess I have made the DCP to loud but the popping surprises me, is this normal if the DCP is too loud. Looking at the audio graphs in DCPOMatic it looked like it was peeking about -12 db. I guess the best thing is to use the level calculator and make 3.5 come out as 5. The 5.1 is mixed to 0db and I had a -1db audio tweek in DCPOMatic. The other issue is that there seem to be some blown whites. I have been trying to find out what the grading was set up for but used 2.4 as they are being non responsive (I have been told it is Rec.709). What effect is using 2.2 or 2.6 going to have. If I go to 2.6 am I correct in thinking the image will go darker. The thing is there are some very dark scenes. My understanding is that at the ends of brightness (very dark and bright) changes in the gamma curve used have the least effect. i did ask if the whites where ever meant to be blown (its a found footage mockumentery) and the answer was no. Any advice?

[DCP-o-matic] Does triming work

by Ben Edwards

Hi, the fiml is 1:48. I started creating DCP then thought I should try just the first 30 mins. When I restarted (after deleting stuff from the directory and setting triming, and not forgetting to press set.) it still says it will take 16 hours. Framerate has gone from 3.9 to 2.6;(.

[DCP-o-matic] Audio Levels

by Ben Edwards

(This is from a previous tangental thread) "When using DCP-o-Matic, I check if center channel "peak" is around -12db. Certainly not scientific enough but most of the time it ends with a normal human bearable audio level. It becomes more difficult to "predict" with 5.1 audio using phase inversion, as you need all the channels to get not only a good balance but something human-understandable…" Gérald Maruccia I have a 5.1 mix peaking at 0db. Any advise on what to do. I dont quite understand the 'I check if center channel "peak" is around -12db', well I understand what it means but dont know to do it in DCPOMatic.

[DCP-o-matic] KDM delivery CC: address

by Carsten Kurz

I know it was my own idea - but maybe it is better to make the CC: address a BCC: ? Because in general the KDM receiver shouldn't see it. No big thing, but... Or may just offer both, I think there is still enough space on that tab. Commercial KDM delivery emails usually have a bunch of recipients for internal and external reference. Sometimes half a dozen people receive an individual KDM Email. - Carsten

[DCP-o-matic] Prores 422 vs 4444

by Ben Edwards

Been doing some digging and it seems 4444 may be overkill. The colourspace and bit depth are higher (bit depth 12) but if this is beyond DCP is seems pointless. Also in the preview (after file imported) when I look at same clip in 422 and 4444 the 4444 one looks pookier with better blacks and the 422 one looks a little flat/washed out. Is this just the preview? Has anyone done any comparisons on high end footage?

[DCP-o-matic] Windows Notebook falling to sleep during Encoding went sent to background

by Carsten Kurz

YES, it IS a boring flic, indeed, but does that justify falling to sleep while rendering a DCP? 1.72.2/64 After starting the DCP job, I just switched to the Desktop to inspect a folder and left it like this. After a while I came back and the notebook is sleeping. After waking it up, it continues rendering without any messages or errors. I'm just wondering wether the encoded images/MXF are correct? Is this normal? I remember reading some issues about fixes against machines falling to sleep in some release notes. - Carsten

[DCP-o-matic] KDM - Playout window local time

by Carsten Kurz

Carl, how is DCP-o-matic dealing with local time/GMT when creating the KDM and during email transmission? Will it automatically convert local machine time to GMT according to machine time settings? Then how is $START_TIME and $END_TIME calculated and displayed? All KDM providers we dealt with so far automatically convert to local time for Email transmission notification text. That is because they have a location and time-zone associated to every cinema in their database. - Carsten

[DCP-o-matic] recursion

by Carsten Kurz

Right now it is not good for much, but still interesting - ffmpeg added J2k MXF support a while ago, and since dcp-o-matic uses ffmpegfor input, it is actually possible to feed a DCP-o-matic generated J2k-MXF (or from any other unencrypted DCP) into DCP-o-matic as source content. Right now, the only option then is to recompress it into another MXF, which is hardly exciting. But - wouldn't this be a starting point for 'unwrapping' and transcoding of existing DCPs to other formats, again by using FFMPEG, this time for ouput? - Carsten

[DCP-o-matic] videos is copied or hardlinked?

by Manuel AC

I remember something about the mxf file being hardlinked and not copied from the "video" directory to the final DCP directory, or moved as the sound mxf. But OSX keeps giving the size of the full project directory as about double the size of the DCP. And had many times the error when trying to make the DCP sirectly in the usb key where I intended to deliver the DCP, so just slightly bigger than the expected size, not double. If the files are actually copied, an option to specify a different location for the result DCP will be great in many many cases. Thanks! Manuel AC

In the case of e.g. Big Buck Bunny the 'Master' would actually be bored when only supplying a bunch of unprocessed 853*480 pix to the remote nodes. As long as we think of a 'classic' DCP-o-matic workflow, that is, conversion of pre-encoded video to J2k-MXFs, I think mass storage performance is not so important - because we come from a low-bandwith compressed video format and go to a medium-bandwith compressed format. Again, in the case of Big Buck Bunny, we have a videostream of 11Mbyte (that fits into the filesystem cache) with around 350KByte/s and end up with two MXFs at something like 25MByte/s - but with the encoding an thus file write performance on said CPUs is taking place at half realtime speed. So, typically we come from something like 1MByte/s and go to 15Mbyte/s. That's well within the limits of common single drive hard discs. This, of course, changes dramatically when working from uncompressed single image sequences (like most other DCP encoding tools do), or very high quality FullHD sources with low compression ratios. - Carsten

Some of those machines I gave Carl benchmark data had SSDs, but it wasn't really visible from the results. But then again, they were all only testing on 'tiny' big buck bunny ;-) When a GPU assisted OpenJPEG will be there, mass storage performance might become more important. Carl - did you ever think about implementing support for e.g. Kakadu? I'm quite okay with the current coding speed and options for network rendering, but I'm not using it for large projects on a daily basis like others might do. - Carsten

[DCP-o-matic] DCP-o-matic 1.70.0 is now available

by Carl Hetherington

Hi all DCP-o-matic 1.70.0 was released. This version includes: Updates to the de_DE translation from Carsten Kurz. A fairly big code rearrangement to improve speed of encoding of DCPs from sets of images. Improvements to the KDM dialog which now takes CPLs rather than DCPs. It also allows you to specify any CPL to generate a KDM for. Improvements to the timeline dialog when dragging content over other content. Various fixes to uses of separate audio files with accompanying non-standard frame rate video; video rates are now derived from simultaneous video sources. New "scale to fit width" and "scale to fit height" options to adjust scaling and cropping of a source to fit the DCP's container. Use the ISCDF DCP naming contention version 9. Some fixes to audio analyses when channel mappings are changed. Fix to linkage of command line tools on OS X. Fix to crash when the timeline window is opened when there is no content. Fixes for crashes when using sources with more than 8 audio channels. Fix for bug where video would not be re-made if subtitles were turned on. Speculative fix for completely broken DCP XML files in some locales. Possible fix for missing bits at the end of FFmpeg content with negative start times. Option to allow any DCP frame rate, not just the ‘approved’ ones. Audio gain can be specified in fractional dBs Work-around out-of-memory crash when using large start trims Fix incorrect labels for some audio channels in some locales. Add slightly better and more configurable logging. Thanks to Sumit Guha, Pradeep, Carsten Kurz, Matthias Damm, Bill Hamell and Daniel Chauvet.

[DCP-o-matic] Benchmarks/network coding

by Carsten Kurz

Attached two pictures with recent benchmarks, using 1.69.xx. One single machine testing, one network. The single machine lists only the peak performance runs, as most machines were tested with different encode thread numbers to find the best setting. It can be seen that 'overthreading' will help a lot on current multicore CPUs. Be aware, though, that this might crash the software if running under WIN32 OS. I can easily be seen that the price/performance sweetspot is with the 6core 3930k/4930k machines. They can even be overclocked to 4.5GHz. This CPU costs only around 500€ or so. This is also reflected in the CPU Passmark list: http://www.cpubenchmark.net/high_end_cpus.html I was always skeptical about network encoding with regard to achieving very high conversion rates, because I thought a typical network (even gigabit) would saturate too quickly, already around 10fps or so. I was wrong. I set up a test at a clients site with a couple of (mostly) older Macs, connected through a simple Gigabit switch. Nothing really fancy. Two iMac-i5 were the most beefy machines. The network still outperforms the fastest (and most expensive) dual Xeon machines. These tests also show that the J2k coding on the Mac is at least as efficient as under Windows. Although I still have to perform the identical test on a Mac with OSX vs Bootcamp one time. The network test was done with all machines running OS X, adding one machine by one and running a BigBuckBunny encoding for each set. And of course this was using Carls standard Bunny benchmark metadata, so 2k - the network load may look VERY different when using 4k... It's interesting to see that the 'Master', an outdated Xeon 3530, is able to supply so many frames to the clients and is still encoding many frames itself. Only with the last iMac-i5 added to the network I could see the occasional drop in CPU load on it, but very short and rare. I guess I could have gotten near 20fps by adding another. The number is missing in the table, but aggregated single CPU fps for all machines used is around 19 - that's just 2fps loss in the network coding performance. Good work, Carl! Also, not a single run exhibited problems. No crashes, no lost frames, etc. I also did a SINTEL run on the same network, giving the same performance (17.3fps) and taking just 20min runtime. Carl - what is now done on the render clients - only J2k, or also colour conversion, scaling, etc.?

[DCP-o-matic] weird colors

by Manuel AC

Maybe someone else had a similar issue. Did a short film, mostly B&W. In a quick projection test I saw some, very few images with posterized green colors, and it's not an effect of the film. Cinemaplayer renders it perfectly from the mxf, and I'm wondering if it's a problem with the cinema (Doremi+Christie), but I don't have easy access to it. It's worth trying another codification? like going the long way with opendcp. Oh yeah, the source is a prores 4:3 interlaced SD with rectangular pixels, funny stuff. The deinterlacing filter made the weirdest flashing colors, so I deinterlaced before, but scaling and stretching is done in dcpomatic. Any ideas? Thanks! Manuel AC

[DCP-o-matic] ISCDF DCP naming contention version 9

by Jonathan K. F. Jensen

Hi Carl. Just a heads up. In the current test version (v1.69.35), the DCP naming convention v9 isn't completely integrated as far I can see. Currently, if I put in this text in the 'Name' box: *ActionNightTF4* I get this as DCP name: *Actionnighttf4* Only the first letter is capitalized, even though the v9 of the naming convention says the following about the Film Title field: "Words should be seperated by initial caps: MovieTitle". Please let me know if I have overlooked something. Thanks for a continuing fantastic effort with DCP-O-Matic (can't be said enough)!! Best regards, Jonathan
