OpenDCP / Re: can't seem to get a flawless check with title name
« Last post by hdvprojection on November 19, 2017, 01:09:23 PM »
I always get 4 hints, and no, I don't lose any sleep over them, but I do find it curious why I cannot get rid of them.
Code: [Select]
Naming convention: 3 parts missing: content_kind, territory_rating, package_typeThe only one that is actually ever missing is the rating, since nothing I encode ever has an MPAA rating. What gives?

I realize that this may or may not be verboten here, but I've tried posting to their forum and no one responds. Besides, I noticed Terrence's name attached to it as a dev, so...

I can't install DCP-O-Matic on my Linux box, only on the Windows side of it. It keeps saying
Code: [Select]
Couldn't find any package whose name or description matched "dcpomatic_2.10.5-1_amd64.deb. Unable to apply some actions, abortingThis would suggest that I've either misnamed the file in the install command, or that I'm in the wrong directory. Neither is the case, I assure you. I cd to the correct directory, and I drag-and-drop the file into the install command.

Has anyone else had issues with this, and how did they get around it? Thanks.
General Discussion / Re: Open Source/DIY Playback Server?

I have also been considering building a DCP player for 2 small venues. I small auditorium (30 people) and a small theatre (100€).

I have been keeping an eye on these: Intel Core i9 7900X. This one packs 10 cores. But costs around 1000€.

I'm guessing the real problem is the software to play the DCP films correct?
I haven't been able to find any open source solution and the VLC attempt kinda seems like it has gone cold.

I can try to afford a computer setup for 1500€ but there is no way I can afford an additional 2,975.00 € for EasyDCP or the weird options from NEODCP which I believe the most suitable one would be the "Ultimate 2k" for 1299 € which only gives me a licence for 4 years.

General Discussion / Accessing subtitles from a DCP server?
« Last post by hmpws on June 23, 2017, 10:41:11 PM »
Hello everyone,

Is it possible to access the closed caption track on a DCP server (e.g. a Doremi DCP-2000) connected to a cinema projector? Perhaps through serial or network ports at the back?

I am still relatively new to this field of cinema projection but I am working on a closed caption device with better display technology. The local cinema chain seems supportive and has allowed us to do some testing there.'

Digital Cinema Packages / Re: 3D stereoscopic DCP bitrates
« Last post by Terrence Meiczinger on June 23, 2017, 09:00:34 PM »
While each "frame" might still be read sequentially by the digital server, they must be processed twice as fast. A 24fps 3D picture needs to process the content at 48fps in order to be able to get the images to to projector at the same time. So, rather than think of it as left/right, think of it as single stream of data which gets processed into separate channels. The stream can't exceed 250mb/s (500mb/s for newer systems) and the frame rate or number of channels within it isn't really relevant.
Digital Cinema Packages / 3D stereoscopic DCP bitrates
« Last post by rconnew on June 22, 2017, 10:15:19 AM »
The way I understand it is the maximum I can have each eye (Left and Right) set to is 125mbs and so the total DCP doesn't exceed 250mbs. Surely this could be higher as each frame must be separately processed; or are they both processed and displayed at the same time?
Many Thanks

OpenDCP / Re: Sound in and out of sync with Sony projectors
« Last post by rconnew on June 20, 2017, 06:20:19 AM »
Ok finally I have I believe found the answer. J2000's from Resolve don't work well on SONY projectors if they work at all, but they do seem to work on other projectors providing the bitrate is 180 or lower - tried one at 180 and it just about worked. SONY projection system doesn't like any blank bits at all in the name it must all be filled in. Again other projectors seem to be ok with the odd blank.

Solution work flow.

Resolve output master file to TIFF XYZ at 16bit uncompressed. An observation I made was with cineform avi files you must select video levels as auto makes the blacks appear crushed which I suspect is due to the gamma level it thinks its at or not as the case may be. Didn't try it with other forms as I'm working with a cineform 3D avi master albeit split into separate L and R for this but its something to look out for if you get that problem.

OPEN DCP - Convert to J2000 - bitrate 180 - 230 seemed to work best - noted the higher the bitrate the richer the colours appeared to me on screen. XYZ Transform and DPX Log unchecked. Make MXF as normal. Works great and more importantly looks great Tried it at 230 and no problems with picture or sound sync at all!

Seems the non compliant was with the size of the J2000's as they were being output over 250 even though the system said 250. There didn't use to be a means of changing the J2000 size in Resolve away from 250 but there is now in 12.5 and the new 14. Someone told me to set it to 230 hence why I did but without really understanding why that would be a problem. So I'll do a 175 and a 125 version and check the files sizes to make sure they are indeed smaller and go from there. Think this may be the problem thank you.

Thanks I have another test opportunity next week so I'll add a test file with J2000 from another source just to be sure.
