Hello everyone,
I have created four 24- to 32-minute long DCP packages for a friend and
hobby filmmaker who is going to screen them at a local movie festival.
Now, I've heard back from their technical department that the DCPs I
made using DVD-o-matic are single-reel and that "might cause problems",
whatever that means.
As far as I understand it, there is a convention to limit reels to
somewhere around 22 minutes (e.g. typical old "analog" reel size) to
minimize problems in transfer and handling and to keep the sizes of the
files in the DCPs reasonable. But I wouldn't have thought that a
32-minute single-reel DCP might be problematic. Can anyone enlighten me
on the subject? I'm no projectionist or TMS technician (I'm helping my
friend because I have maginally more hobby experience creating DCPs than
him), so there's a huge question mark hanging above my head. :-)
Furthermore, is there any possibility to create multi-reel DCP packages
via DCP-o-matic, or to convert the single-reel packages into multi-reel
using open-source tools?
Thanks for any help in this matter

Hmm, I reported this GAMMA issue before with a BluRay conversion around the beginning of June.
Now I did a parallel conversion of a DV-compressed AVI file to a DVD-Video and a DCP, both on a Mac. While the DVD retains more or less the same contrast and colours as the AVI file, the DCP again came out a lot brighter with greyish blacks (played back on our DCI projector). The BluRay conversion I reported back in june was done with the windows version from a 1:1 rip/MKV container and it had the same issues. I needed to create a special format on the projector reducing brightness and saturation considerably to make it watchable.
Hmm, I now see that DCP-o-matic has an explicit dialog for input/output gamma settings and color conversion matrix. Maybe I will try to do some tests to find out wether these issues can be solved by this. Really wondering why no one else is having this issue, as it is not just a minor variance but a heavy one.

Hello there.
I got an Error when using DVD o matic that looks like so:
Transcode job failed (Cannot handle pixel format 102 during make_black())
The suggestion was to mail it, so here it goes.
The source film is in Prores4444 1920x1080
The audio is external in 6 * PCM 24bit WAV files
No subs yet
(Mac version of DVD o matic because of the Prores source)
I specified the start frame to 3 and end frame to 36875 for a 5 minutes
test. But the encode seems to have run from 0 to 42571 where it stopped.
I wanted to ommit the syncblipp at fram 1 but I can hear it in the file
generated in the DCP_XX-XX.... folder
Any suggestions are appriciated, did I mention that I like DVD o matic a
lot =)
Attaching the log file.

ps" I see now that I had "encode all frames and play the subset" on by
mistake. But does that mean that I will get this error when trying to
encode the entire movie later?
