Part 2: Real Work
Action Item Review from last meetings…
Updated Digital Cinema Naming chart has been posted to ISDCF site - current version on the official site is slightly out of date.
Radoslay has posted content for subtitle rendering and tests have been made (updated links on ISDCF site for test content)
SMPTE-DCP test package B almost finalized (MCA numbers need to be fixed) (updated links on ISDCF site for test content)
The movie “Finest Hours” in January is planned to be issued in SMPTE-DCP. Norway and Holland for “Finest Hours” SMPTE-DCP as well. This should be with feature set similar to Test Package B (including CPL metadata and markers). Other titles are being considered, HOWEVER if other studios don't step up to release content, this studio may wait on additional titles.
Paramount had planned to release a title in October, but that title has slipped to January - no update due to lack of attendance at this meeting.
All other studios interested, but nothing planned at this time.
The Test Package B, Version 2.0 is testing well at this time. [Could be called Test Package B' (B-Prime).] Problems detected so far are known issues with the authoring, not due to field hardware/software issues. Things are looking good!
Current Test content is located at:
http://isdcf.com/SMPTE-DCP-Content/SMPT ... _SMPTE.zip
http://isdcf.com/SMPTE-DCP-Content/SMPT ... _SMPTE.zip
These are close to final, but still have some internal details to be “fixed,” but should work just fine on all systems.
Test Package B Version 2SMPTE DCPAudio SMPTE Configuration 4 - with Audio in ISDCF Interop LayoutSubtitles (no entry point duration)CPL Metadata - including MCA descriptorClosed CaptionsOpen CaptionsMarkersRatings3D subtitlesTKRAudio track file includes MCA labelsMastering can do these, Playback doesn't crash and may use the feature.
Subtitle Sync Test Content (Radoslov).
http://isdcf.com/SMPTE-DCP-Content/sub_ ... ew_one.rar
(Four packages - for testing on both projector rendered and server rendered.) We will use this content at the plugfest. Some testing has been done with results reported - generally good results (we will talk about the expectations at the plugfest). It has to do with the entry point on the subtitle files.
“Walled Garden” SMPTE-DCP expectations
“Take what you like and throw away the rest.”
Content on single drive / multiple folders (one CPL per folder) Including: Dolby Atmos, DTS-X, 5.1, 7.1, Interop-DCP , Barco Escape, ScreenX, word document, jpeg, tiff, pdf, Dolby Vision DCP, fox timed text multi-reel test. This will be prepared by Deluxe/Technicolor on a single drive for the plugfest.
Note: some servers/TMS systems scan the entire drive for suitable files and when a drive has thousands of TIFF files it can slow down ingest. This is NOT a fundamental issue, but a design “feature.” We will not add this to the test content.
Plugfest Planning - November 9/10, 2015 - Deluxe Hollywood
What needs to be prepared?
1. Walled Garden Test content on single drive / multiple folders (one CPL per folder)
2. Test Content B v2.0 (5.1 and 7.1)
3. JDCF subtitle testing (video record only)
4. Eikon 3D subtitle test (variable Z) Jim Whittlesey
5. High Frame Rate test content 2D60, 2D120, 3D60 with subs/etc.
There is a desire for 3D subs with changing Z during a single subtitle presentation (as opposed to a fixed Z for each subtitle). There was a desire to get test content to demonstrate this concept. Jim Whittlesey stepped up to create test content.
(Fun Fact: 30%-50% of current 3D movies use moving Z for each subtitle for burned in subtitles.)
Event being planned for theatrical mix of “live” content (video feed) with DCP packages with 3D60. Jim Carbonetti may provide test content for this plugfest… Discussion on how the switch between “live” and DCP… not sure how it's going to work. February time frame for the show (Fathom presentation). Jim may bring content to the plugfest and may test the switchover.
Scheduled a plugfest call for Friday October 30 at 8:30am.
Naming Convention - revisited
Need to add to the naming convention to include Dolby Vision. Modified
There was suggestion to include a few new pages to the website that gives details for CPL metadata that includes the extension of FLM MXF details as new content types are added. Pierre will draft a page / pages to consider. It may be only proprietary data that are extensions that are outside of SMPTE documents.
Some discussion on the use of proprietary data that is part of the CPL metadata being documented in any posted document. No final resolution and interested parties will consider the recommendations and will comment on the draft documents that are shared to be posted.
We have run out of space in the traditional naming convention. Need for something to the REGULAR naming convention that says, basically, “this name does not reflect all the details of this content, see the CPL metadata.” We think we can add to the front page of the digital cinema naming convention. It would be an additional paragraph:
The prescribed name doesn't necessarily reflect all attributes of the referenced presentation. More information may be found in the CPL metadata.
Forensic marks in dual projectors
We continue to look for solutions to the problem of multiple IMB's / multiple projector embedding multiple forensic marks into a single image on the screen. The problem is two overlaying forensic marks. Any input can be sent to the email@example.com email address.
SMPTE: Very active - can not be discussed in this public forum. Contact Pete Lude or a participant in the SMPTE working group 25css.
Still issues in Making DCP's for independent Film Makers
Amazing number of errors made - From wrong aspect ratios to bad subtitles to following the Academy 2048x1080 requirements (full container). The document is posted in the meeting folder. It's still a mess out there in the real world.
A need for a book on “so you want to make a DCP?” or “So you want to make a movie and distribute via DCP - a how-to guide to get it right.” No clear way to provide education.
One idea floated was to REQUIRE a signed DCP. Not embraced by most participants.
Is there a chance to connect with an academic link (i.e. USC/RIT) to help educate upcoming filmmakers. Action: Jerry to connect with Elizabeth Daly. Bill Hogan may contact RIT.
Topic for HPA Tech Retreat round table.
SMPTE process going well. End of 2015 anticipated a almost-final draft. It will be off the list for next meeting - tell us when it's done.
Filmmaker releasing 70mm film prior to and a different cut than Digital Cinema. Interesting development.
There are encouraring signs that SMPTE is working on making openly available XML documents defined in SMPTE engineering documents. (The engineering documents will presumably remain for sale .) We will get post link when available. Perhaps an on-line schema validation service would be helpful (after the meeting many links were shared).
Recommended practice for subtitles
Better if subtitles are split into reels. Large files cause problems to the installed base.
