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

[DCP-o-matic] Merging test versions into stable

by Jim Dummett

Hi Carl. I'm just wondering how/when you go about merging commits from the test version into stable branch? For example, a feature request I made (https://dcpomatic.com/mantis/view.php?id=1284) was implemented in test version 2.13.19. Since then, stable 2.12.6 has been released but does not contain this commit. Stable releases since 2.12.2 are bug fix releases. However, what confuses me is that there are many more bug fixes which have been committed to the test branch. So there's obviously some criteria for what makes it through to stable and what doesn't. If you can be bothered, can you explain the release strategy a little bit? And do you have a rough timeline of when the next stable release is likely to be? Just asking as I'm planning ahead to an upcoming festival and wondering what version to settle on. Many thanks, Jim

[DCP-o-matic] Christie cert database?

by Jim Dummett

Hi all. Is there anyone out there who has access to Christie's certificate database and would be willing to look up a couple of certs for me? Have a show on Friday and we're using mobile projectors which are currently locked in a warehouse in middle of nowhere, so it'd be a pain to get them out to extract the certs from them. For whatever reason, the owner of the projectors doesn't have a copy of the certs. If anyone can help would be amazing! Many thanks, Jim

[DCP-o-matic] DCP-o-matic 2.12.8 is released

by Carl Hetherington

Hi all, DCP-o-matic 2.12.8 is now available from https://dcpomatic.com/download This is a bug-fix release which corrects some problems with 2.12.6, and provides a couple of small improvements: Fix failure to load image files with non-ASCII pathnames. Fix some reel length errors at the end of transcodes. Prevent the introduction of negative trims (which cause encoding errors). Assume .jpf files are JPEG2000 images. Fix the update checker (#1338). Speed up the timeline in some cases. Add build for Fedora 28. Special thanks to our subscribers and supporters! Kind regards, Carl

Re: [DCP-o-matic] Strange colors artefacts since PREMIERE CC last version

Désolé que je ne peux pas aider plus…I haven’t touched Premiere since 1990s! The never changing rule: Entertainment Technology Debug Question One: What else has changed? Entertainment Technology Debug Question Two: What else has changed? Of course, you wonder if DCP O Matic has changed…? When I google Premiere update color shift – many answers, some recent, many old. =-=-= The right color space depends on the capabilities of the equipment that you are using, the client’s release format, and importantly for you, the archive format. A library has value only if it keeps up with current trends. For example, a VHS format and color space has little value today – it is unwatchable and cannot be upgraded easily or well. And more than one streaming service is demanding P3 4K minimum. All trends are toward more and better pixels: How soon 2020? The best that the client can afford today! But you are the client!!! The trend in the standards world is toward a high grade mezzanine format for archiving and a lot of metadata for different iterations and evolutions. SMPTE ST2065 – Academy Color Encoding Specification (ACES),and ST 2067 – Interoperable Mastering Format (IMF) detail the entire path from production to various forms of exhibition…and those standards continue to be worked on. I don’t have a specific answer to “Right Color Space for Premiere” but it seems that the answer is a constantly improving workflow for deliverables that are going to be under constant pressure for better and interchange software that will help advance that.

[DCP-o-matic] Re-using source video with re-encoding

by Tom Haines

Does anyone know if it's possible to build a DCP with DCP-o-matic that repeats a source file a number of times, but only encodes it once? So essentially the CPL would point to the same asset multiple times. I'm adding the source video multiple times in the content tab, and then selecting "split by video content" for reels. This still re-encodes each instance of the source video. -- TOM HAINES Screenings | Originals Publicity M: 310.467.3069 | thaines(a)netflix.com 5808 W.
