Is there a method to "unpack" a dcinema file to play on a computer. This is an ad to play before the main feature.

---

There is player software like EasyDCP or the digitall player for unencrypted DCPs.

You can also unwrap or play the individual MXF files in the DCP, e.g. with stereoscopic player or VLC. Again only if they are unencrypted.

How to encode jpeg2000 the fastest?

I'm using OpenDCP and the converter uses CPU power, allows multi-threading, but don't know if it would use up all cores / threads in letssay i7 6-core. Anyone have any info, how it handles that, and how fast it goes? I'm currently getting roughly 1-1.5 frames per second from my dualcore, which is not bad.

I have been looking at the jpeg2000 plugin for Adobe Premiere, but cannot find if the encoding to jpeg would use up the nVidia CUDA cores, as that would probably speed up things alot. I know Premiere uses CUDA for regular encoding, but no info if it works and how it works on jpeg2000.

Any other programs that do jpeg2000 and utilize GPU power?

I really would like to make things a bit faster and am thinking of upgrading my older computer, but don't want to waste 600$ on an i7 and motherboard if i can get the same encoding speed boost from i.e. a gtx560 with 400 CUDA cores for 200$.

Any info appreciated.

I seem to remember that the Windows version of OpenDCP won't utilize more than a single core. The Mac version will.

Commercial software such as easyDCP are significantly faster than OpenDCP, which uses the OpenJPEG library for encoding j2k files. OpenJPEG is open source but less optimized performance-wise compared to the commercial stuff.

See the Making your own DCP's thread for some discussion on hardware.

To summarize: your system has to find the right balance between different components or you are going to be limited by the weakest link in your setup. The fastest processor in the world is not going to help you any if your discs can't keep up the required data rate.

My current 3 GHz Intel Core i7 950 based PC can achieve 0.4x encode speed (i.e. encoding takes 2.5 times the playback time) with Fraunhofer EasyDCP and is CPU bound (i.e. the CPU is the limiting factor). Now, if I were to upgrade the CPU, the disc I/O would become the limiting factor (i.e. the system would be I/O bound).

using an older intel core2duo, in task manager it says it utilises both cores to near 95%. windows vista 64bit.

some people on the openDcp forum mentioned running 4 cores at roughly 50%, but the posts are somewhat old.

@jussi:
yes, that i am aware of, but at the moment, with 1.5 frames per second max, i am not touching the threshold of the discs in an way. I am looking to improve from 1:20 ratio to something like 1:5 (would be really really great), that is cca 5 frames per second. That would be 25Mbit/s and would still be well below what average disc read/write operations are.

/edit. ah yes, the tiff/bmp files are larger, so esentially the read would have to be at cca 250-300Mbit for 1:5... ok, back to the drawing board

If you are hitting disc IO limits with your encodes with OpenDCP then DVD-o-matic might help a bit, as it goes directly from the source video to JPEG2000 without needing a disc write/read to/from TIFF.

There has been some open-source work on J2K encoding using CUDA, which I keep meaning to look into when I get time.

As regards a Mac OS X version of DVD-o-matic, there isn't one at the moment, but I'm happy to take donations to buy a Mac Mini to do a port on

I'm still happy to hear about any problems anyone is having; either to the mailing list dvdomatic@carlh.net or my email cth@carlh.net.

A quick demonstration of the principle of having a balanced system I mentioned earlier:



- Discs don't need to be any faster, because the CPU is fully loaded
- CPU couldn't be any faster without the discs becoming a bottleneck

Recent versions of OpenDCP should use all cores on Windows. Early versions didn't because the application would exceed the 2GB per process memory limit on 32-bit Windows and crash.

There are other processing limits, such as I/O, so more threads doesn't always mean better performance. You may need to adjust the number for your system. For example, on my 8-core Mac Pro, 6 threads is usually optimal when using OpenJPEG. When using the Kakadu encoder, just 1 thread is needed because the encoder is highly optimized and simultaneous encodes starve each other.

GPU encoding for JPEG2000 isn't going to be all that beneficial over well written CPU code. The costs of GPU setup and memory transfers will outweigh the computational gains. GPUs are great for certain tasks, but it's not simple as just throwing GPUs at everything. Decoding on the other hand could benefit from GPU processing.

Anyone have any comments about using Windows Movie Make to create input for DVD-o-matic? In a 90 second clip, the sound go terribly messed up in the last 15 seconds. The sound was a .wav file; the video was a series of stills. WMM's output is a .wmv file as opposed to a .mp4 which seems to work fine.

Ok, you've got your new home-made DCP authored and now you ingested it. Question is, will all that high security let the system play it, no questions asked even tho it has no KEY? Or do you create your own key to unlock your own DCP? How does that work?

OK, so I made a very nice "Merry Christmas" tag. It features a snowy picture of our downtown, thus it gets ooohs and aahs from the audience every time it plays. But now, we're playing a 3-D movie and when the tag comes up, the screen goes to all-green, so I've had to take it out.

Carl - Yes, using DVD-O-Matic to make the DCP. We have a GDC server and an NEC NC2000 projector. I made the clip in Sony Video Studio as an AVI so it should be fine from the front end at least.

I also have attempted to DCP-ize a couple of Looney Tunes from one of those DVD sets that came out a few years ago. I used DVDfab to extract the video but DVD-O-Matic gets to about 90% through the transcode process and then crashes. Any idea on that one?

---

Which version of DVD-o-matic are you using? Is the crash during the "transcode" part or the "make dcp" part? Any chance you could send me the log file that is created inside the film directory?

Glad you are having at least some partial success with the -o-matic!

Just wanted to report here that I've been experimenting a bit with DVD-o-matic and have reported a couple of issues to Carl -- he's been most helpful (and fast) in getting things solved and questions answered.

Among other projects, I even downloaded an old "1940s-era" Previews of Coming Attractions clip from Youtube, it looks awesome on the big screen. Never would have thought YouTube content could look that good that big. So now my list of "things to make" is starting to grow quickly.

Bottom line, this program works well and I'm sure I'll be making a lot of use of it. Thanks Carl!

DVD-o-matic is a godsend, thankyou so much!

Using KDEnlive (linux video editing software) to generate a mpeg2 from some still images, and then DVD-o-matic I have been able to create a simple, but effective "Coming Soon" short customised with our business logo and some other stuff. We play it just after the ads before the trailers.

Rendering the mpeg2 @ 24fps in KDEnlive means we dont get any random flashes of junk on the screen, and the ability to name the end DCP anything we want (like PAC-COMING_SOON) without all the other DCI naming stuff is a brilliant feature. Makes building the shows very easy

So, thanks very very much for the brilliant and free software If you had a donation link on your website i would buy you a beer!

I created a one-minute plain black DCP called "Roxy Show Open" and a six minute one called "Roxy Close." I put these at the beginning and end of all my various templates, along with the necessary cues for starting the movie, shutting down the projector, etc. This takes the place of having to use multiple 30-second "MOS" clips and this way I can make sure that all the cues stay in the right places. Once the playlist is built, the only cue I have to add is the "lights mid" cue at the start of the end credits.

Thanks Carl, for your help over the weekend regarding that DCP still you made.

I have now made a few DCPs and I have run into a sound issue:

I created a DCP Trailer for the film "Amour". We hadn't received one and we are playing the film as part of our "Encore" series in a few weeks and I like to run the trailer to let people know we are getting it.

I downloaded a 1080p .mp4 version of the trailer and ran it thru Dvd-o-Matic. It created the package just fine. I tested it this evening and the picture was awesome. However, the sound was tremendously loud. I had to run upstairs as it was piercingly loud. What's the best way to handle that? Lower the decibels when I create the file? How would i know to do that ahead of time?

Thanks.

I have found that it helps to look at a downloaded video in some video editing software that shows graphical waveforms of the soundtrack. It takes a little bit of practice but you will eventually know what the "proper" volume looks like on the waveforms. You can adjust that volume in your video software and then make your DCP.

The software I use is Sony Video Movie Studio (it's something like $79) but I'll bet there are lots of other alternatives out there.

Posted by Carsten Kurz (Member # 5396) on 02-21-2013, 06:18 AM:
 
Best practical solution is to extract the audio/MXF from commercial trailers and use them as a hearing reference. E.G. you could extract the audio part from a few different types of trailers - action, romantic comedy, whatever.

Then you simply play these through VLC in comparison with the audio you want to compile into your DCP.

There are proper LEQ/ITU based VU meters available for video editing software, but they need some special knowledge to be set up and used, so I think the direct listening reference is the most practical approach.

Another one, of course, is to always create 3-4 different versions with different sound levels, then test each of them on screen and choose the best one.

Posted by Aleksandar Obradovic (Member # 7266) on 02-21-2013, 04:31 PM:
 
Of of solution is to normalize sound levels with SoX (Sound eXchange) but you have to be familiar with command line/console within your operating system. I am using this occasionally during DCP creation process (OpenDCP is my choice btw).

Command to normalize sound of 5.1 audio channels looks like this (i assume that you already have all channels separated):

sox left.wav norm -20 remix 1
sox right.wav norm -20 remix 2
sox center.wav norm -20 remix 3
sox lfe.wav norm -20 remix 4
sox ls.wav norm -20 remix 5
sox rs.wav norm -20 remix 6

Of course you can build script when you find right level which suits your needs. I made one such script which covers entire DCP creation process with OpenDCP (con is that i have to always use same folder and same filenames except for wrapping which is handled by another script btw)

A little bit off topic question
Some of you guys and girls has knowledge of open source KDM generator???

Is there an easy way to get a DCP back to a HD video file

To do what with it?

Unwrapping is one thing. Playing back a J2C-MXF another.

Unwrapping only gives a folder full of j2c files. Transcoding? Yes, but takes time.

Unwrapping is CLI with asdcp-test, but can be be made drag'ndrop easily under any OS.

A proxy solution with CPL parsing like Wolfgang mentions it is a nice testing tool until capable players (and hardware) turn up.

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.

Posted by Carsten Kurz (Member # 5396) on 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.

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.

Posted by Carsten Kurz (Member # 5396) on 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, 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

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.

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.

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.

DVD-o-matic 0.76 download

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.

Cameron,
Does the IMAX server possibly only recognize EXT3 formatted drives and the drive you have your file on is not formatted that way?

Carl,
DVD-O-Matic has been a huge help at our theatre. Being an arthouse we often have to make our own DCP trailers for upcoming series or from downloaded or pro-res trailers. We have even found a work around for the default L,R only you typically get when downloading pro-logic LT,RT trailers from the internet. We put those trailers together in our playlist so that we can switch our Datasat AP20 to 2:4 matrix mode for those trailers and switch it back to default when they are over. I haven't yet found a free program that will demux the LT,RT to convert it to 5.1 wav files to drop in to DVD-O-Matic yet so until then this is how we do it. We also use your encode servers on our a couple of other PCs on our network to dramatically cut down encode times. Keep up the good work!

Posted by Carsten Kurz (Member # 5396) on 06-10-2013, 04:59 PM:
 
I have suggested to Carl to enable an option for stereo->2.1 decoding, maybe even ProLogic etc. ENCODING and ProLogic->discrete decoding.

As far as I know, FFMPEG has that functionality, and indeed, the AP20 does an excellent job - IF the material is actually ProLogic encoded and not just plain stereo.

There is an even better surround option in the AP20, that is, dts NEO6. Unfortunately, it is only available for NonSync Sources, not DCI content. It does an excellent job to place dialog on the center speaker. We use it all the time when we play alternative content with stereo tracks from media-players, notebooks, etc.

I am trying to convert a piece of video for a special show this weekend and have an "issue."

The picture looks good unless something is moving quickly L-R on the screen....then, the moving parts of picture seems to split horizontally into small segments briefly, like part of the picture has to 'catch up' with the rest of the picture.

I'll paste in a section of a picture that illustrates the problem:

I tried looking at the video from the VOB files in the DVD-o-Matic player, and also tried converting the video to an avi using Handbrake...the results are the same either way.

I'm using DVDFab's HD Decrypter to copy the video from the DVD. There don't seem to be any settings in that, and besides it's worked for other video I've converted before. This is an old old video from the '50s I'm working on so could that be part of it? It looks fine when just looking at it in Windows Media player.

Can anyone shed some light on this? I hope I've described the problem understandably enough.

What is the frame rate of the source video and what is the frame rate of the DCP? It may not like 23.98fps. Or 29.97fps. It has to be a hard 24 or 30 for best results, I think. Remember... "hard".
 

---

Posted by Mike Blakesley (Member # 26) on 07-17-2013, 05:23 PM:
 
The DCP is coming out at 30, and the source is 29.97. Here is a portion of a screen shot.



I'm not sure if the DCP frame rate is the problem though because this "bad" look is coming from the preview, before the DCP is even created (and the DCP results look the same as this). And, if the DVD is created at 29.97 how can I get around that...if that's the problem?

Posted by Carsten Kurz (Member # 5396) on 07-17-2013, 06:09 PM:
 
That's interlacing, your source footage is 'i'. DVD-o-matic has some processors, including a range of different de-interlacers, to get rid of that. You will lose some vertical resolution, but it's your only choice. Don't ask me which deinterlacer module to use. Just try them on a short snip.

http://en.wikipedia.org/wiki/Interlaced_video

http://en.wikipedia.org/wiki/Deinterlacing

That's normal for DVD content. Only very few DVDs are mastered with progressive footage.

Pushing the framerate from 29,97 to 30fps is the best option. DVD-o-matic will automatically resample the audio to adjust for that. If your server/projector can play 30fps, your fine.

Handbrake has de-interlacing too, I'll try it with that on. I don't think it was on before, at least. I'm doing this while attempting to do my actual job so I keep having to stop/start. Thanks, will let you know what happens.

Definitely interlacing artifacts.

I use MPEG Streamclip to de interlace and to convert to another CODEC before encoding to the final format.

It's an extra step and it takes a little longer but it ensures that the video will look as good as it can before you encode to DCP.

Yes, because the more steps of recompression, the better! That's why I always re-encode my MP3s into M4A before I convert them to WAV. I just wish I had time to convert it into more formats before the final one.

Disregard this post if your "Another Codec" is uncompressed or near-lossless.

I find 1080/60p in, 29.97 out works rather well.

I guess I'm stupid for assuming that anybody would convert to anything but a lossless CODEC when they are editing or as an intermediate step in converting video from one format or another.

I'm still on the learning curve when it comes to all this conversion stuff… Well, all things digital I guess.

Well, in general you don't need an intermediate encoding process with DVD-o-matic, you can go straight from all FFMPEG supported formats to J2k. Unless you need to do really weird things. DVD-o-matic supports framerate conversion, audio resampling, cropping/scaling, trimming, deinterlacing, artifact filtering. That should do for most conversion-only jobs.

Carsten,

Just want to give you a "heads up" and say thanks.
I recently got hired to create a video to play on DCP and I just got paid for the project. It wasn't a super great video but the customer was satisfied and that's what counts. Right?

Anyhow, I want to send you guys a few bucks in donation for your project. It's not a lot but even $30.00 is something. right?

Do you guys have a PayPal account, or something?

Thanks, Carsten!
Just got through with PayPal. Should be coming through any time.

BTW: As I was working on the first project, I had a discussion with the woman who made this independent movie called "Furever." It's about the things people do to memorialize their pets when they die.
http://fureverfilm.com/index.shtml

We played this movie at Mercyhurst and there was a meet n' greet with the director, afterward.

During that meeting we started to discuss how she could distribute her movie as a DCP and I told her about DCP-O-Matic. I told her DCP-O-Matic is what I use and I directed her to your website and gave her your name. That was a couple of weeks ago.

I said that the software was FOS but that she should make a donation if she uses it professionally. I suggested 10% of the profit from her first gig. She assured me that she understands about these things and that she would make a donation if she did use it.

You might want to keep an eye open for any hits from the director or her crew. Not so much for financial reasons but, if people are using DCP-O to make and distribute finished product, it would be a good to have it on your list of credits. Publicity. A feather in the cap, so to speak.

Money is good but sometimes publicity is just as good and sometimes even better.

Oops :oops: Still the program works as advertised. People should know about it.

I still can´t get DCP-omatic work on Windows 8.1 64 bit
DVD-omatic runs fine on both w 8.1 and w 7
Has anbody else seen this.
Thanks

What's the problem? carl@dcpomatic.com or any of the ways listed here would probably be quicker ways of getting help than posting here

I have used this software multiple times to make DCPs for special events. Works good, although in the new version I can't find the option for certain cropping functions(like 16:9 inside scope). So i continue to use DVD-o-matic.

If you have multiple computers on the same network, make sure you use the option to have other computers help with the rendering, makes it go sooo much faster.

Thanks for the software.

None of this was a problem in the "tube" age!

Just one more question on this...can I use a switch to wire these computers together? Or do I need to use a router? (It's not necessary to connect these machines to the internet...or is it?)

When I go to "open" in the batch program (after saving my project in the non-batch program), I select the folder it created. It successfully opens the project. Then I go to "Make DCP" and it starts converting. I can open another project while it's converting, but I can't start that one, or queue it up. "Make DCP" is grayed out.
