Hi all.
Does anyone have any pointers on converting a 3D bluray to DCP? The
bluray which is the source in this case has the 3D encoded as MVC. From
my reading, this means the right eye picture is encoded as a separate
stream (which is a delta from the left eye).
Have ripped the bluray with MakeMKV which recognises that it's an MVC-3D
stream. And the file it outputs appears to be the right size so I think
MakeMKV is not dropping the extra stream or something like that.
But I haven't found any software that can display both eyes at present.
DCP-o-matic doesn't see it, and nor does Bino 3D player or VLC.
I'm on Mac but can get hold of a Windows box if I need to.
Anyone encountered this before?
Many thanks,
Jim
Hi all.
A filmmaker has sent me a DKDM to decrypt their DCP.
I sent them the certificate chain, and unfortunately they seem to have
targeted the KDM at the root cert rather than the leaf cert, so I can't
"unlock" the DCP in DCP-o-matic.
This particular filmmaker is in a far far away land and has been hard to
get hold of, so I am worried I may not be able to get a new KDM issued
in time for the screening.
Is there any way to switch around the certs in DCP-o-matic so the root
cert is used to decrypt? I can only see one private key in config.xml,
which I assume is for the leaf cert. However, I guess a private key must
have been created for the root cert too, in order to sign the
intermediate cert. Does this private key get saved anywhere?
If anyone is able to help, would be hugely appreciated.
Many thanks,
Jim
Hi Carl, hope all is well with you, I'm a user of your product DCP-o-matic
for two years now and I have to say that it's a very good DCP creator and
one of the best according to the reviews I've seen online. I use it to
create movie trailers for our cinema here in Barbados. Though I usually
receive links from our movie Distributors to download their DCP trailer
content for our screens, if there are any unavailable content I will go to
HDtrailers.net or Thedigitaltheater.com. and download the the content if
available. These trailers which I download from the two sites in the above
have to be prepped for DCP export which I use the DCP-o-matic DCP creator
to finish the trailer.
DCP file size: ( Distributors content file size vs DCP-o-matic file size.)
My observation of file size that the trailer content downloaded via link
from our Distributors have a greater file size than any trailer content
that I create using the DCP-o-matic creator.
I understand that the Distributor's content are mastered in Dolby 5.1 and
mixed in a facility studio with 5.1 audio track stems and full 2k video
content that is then exported to DCP with very expensive DCP creator
software like Easy DCP and Wraptor DCP. but the trailer content download
from Thedigitaltheater.com that are mastered in Dolby 5.1 are copies from
the good content and then converted to MKV and MP4 files that are smaller
in size because of the compression of audio and video bit rates.
If I convert one of these compressed trailer files to DCP using The
DCP-o-matic creator, then compare it to one of the Distributors files (the
exact trailer) there is always a difference in the size of the output file.
Mastering in Adobe Premiere Pro and Audition:
I've experimented with creating 2048x858 2K & 1998x1080 2K QuickTime video
files in Premiere with maximum bit rates and bit depths for optimum picture
quality, and have extracting the 5.1 files from the compressed content
with Audition then export to 5.1 wav files. Then I create and export a 5.1
2k sequence file that give me a 2.9gb or a 3.0gb file depending on the
length of the trailer.
DCP-o-matic export:
After I have imported the sequence file that I have created in Premiere
into DCP-o-matic and make all the necessary adjustments then I make the
DCP. After the DCP is finished, I am seeing that the file existing in the
content folder is half the size of the sequence file. Example! [ imported
sequence file = 3.0gb] [exported DCP folder with ASSETMAP, cpl, j2c, pcm,
pkl, VOLINDEX = 1.5gb.]
There is also a drop in resolutions in the exhibition of the trailer
content although all DCP contents are 2K.
(1) Is the compression rate set by default to 2gb alone for all contents
that are approximately 2 minutes 30 seconds?
(2) Or, is there something that I can do to maintain a maximum quality
content and keep my file size matching the imported file size? Thanks!
Best regards,
Clive.
