  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Hi Agustin,

I had this issue just a couple of days ago. Wolfgang pointed me in the right direction. It's very simple. You simply add another video.mxf.

You may want to name them video.reel1.mxf sound.reel1.mxf video.reel2.mxf sound.reel2.mxf. write in this order in the .cpl and .pkl .map and the dcp will automatically pick them up in this order. You can check it's working by downloading easyDCP player. It will show you the reel order. It will only play 15 seconds though unless you purchase the license.

Hope this helps.

Let me know if I can be of further help.

That worked great! I try to add a subtitle track now. Don't know if easyDCP Player demo will render them.

Would be any way to encrypt an image track using mxflib?
 
Surround Sound.

Here is something that I came up against earlier whilst trying to create an audio mxf file.

Attention! Writing SMPTE audio without channel assignment property (See option -l)

I wasn't sure but this left me insecure about the audio file.

I then added -l 5.1 before each sound file eg. Whole command:

asdcp-test -v -L -c s1.mxf -l 5.1 L.wav -l 5.1 R.wav -l 5.1 C.wav -l 5.1 LFE.wav -l 5.1 Ls.wav -l 5.1 Rs.wav

this did come up without the above warning. Would I be right in assuming that the 5.1 channels are now assigned properly?

Many thanks

Antony

Agustin,

This is pretty much where I am at the moment. Sorry, I don't have any further info on this. If I find out I shall post here.

I'm still struggling with getting the final xmls. I have done my best to find all the elements of the asdcp and OCT and reinstalled as Terence and Wolfgang say but I continue to get the response below. The machine continues to create an empty xml file called PROJ.pkl.xml. What were your code lines for creating the xmls?

sh-3.2# cd ICARE_DCP/
sh-3.2# mkpkl --issuer DumDumFilms --annotation DCPFULLNAME \ PROJ.video.mxf PROJ.audio.mxf PROJ.cpl.xml > PROJ.pkl.xml
PROJ.video.mxf: Invalid CompositionPlaylist file.

The problem is in the "\" before PROJ.video.mxf, the command sould read:
Code: 
mkpkl --issuer DumDumFilms --annotation DCPFULLNAME PROJ.video.mxf PROJ.audio.mxf PROJ.cpl.xml > PROJ.pkl.xml
if you are running it from your media files folder.
Hope this helps.
 
Surround sound,

by the way, the command above for 5.1 surround is correct and it has worked. you must add the -l 5.1 before your file name for it to map the audio channel correctly. This also applies to 6.1 and 7.1

Gentlemen. I've now got the 6 files in a folder. That means I have managed it. Don't know if it works, but getting this far is fantastic. Many thanks for everyone's help.
Christopher (Bloody miracle if you ask me).

PS I have revised the DCP for neophyte's thread on this forum to explain how I got there.
 
Congratulations Christopher. That's great News. It feels like an exclusive club doesn't it???
 
Yup. Just like the mile high club ... just a shed load more useful.

Now for the next mountain to climb. An opensource DCP player. I can't tell you how frustrated I was to only see the first 15 secs on EasyDCP. I couldn't even check if the sync was right.

On the other hand, it worked, so that is still a fantastic moment.
 
Can someone tell me why everyone needs to compile their own Mac version of asdcp-test instead of doing it once and then make it available for download?

Nothing bad about learning to compile your own software in general, but this is a simple converter utility. After all, RED is not expecting us to compile RED Cine-X or other stuff.

Good question.
In my humble, neophyte experience, the asdcp-test files that others gave me did not work on their own. I had to compile them to get a result. the same went for the OCT elements.
 
Also, these elements are in opensource developement, by crazy folk that do it in their spare time. They are not finished products.
 
I had been using the windows binaries so far. These you just copy into your preferred path and there they work more or less standalone. Why wouldn't this work for the Mac OS X versions?

- Carsten
 
Not saying that they shouldn't work. I'm just saying that it was not that easy for me. Also, I notice that for many of the installs, libs were installed that were consulted by the mac.
 
Sniffing about for DCP utilities, I stumbled across dcplint at sourceforge. The site seems empty. Anybody know what it is?

It all depends on how they were compiled. If they were compiled with dynamic or shared libraries, then you need copies of all the libraries on your system as well. If the tools were compiled statically, then the executable includes the portions of the libraries it needs, which eliminates the need to have local copies. There are pluses and minuses to both approaches.
 
Does anyone know if EasyDCP player compensates for the XYZ colorspace to show the right colours? I am looking at my j2c files and they have a strange kakhi green colour shift. When I look at the DCP made from the j2c files in EasyDCP player, I have the same colour shift, and not a correct colour interpretation. Is this normal or did something go wrong? (I hope not)
