Plugfest Breadcrumbs:

Testing sync / data transfer testing.


Test material breadcrumbs:

Mods that would make it even better


1) The audio for the LFE channel could have some low frequency rumble - the brickwall filter works well and we don’t hear anything in the room.

2) Lc and Rc (Left Center and Right Center) were both heard in the theater during 7.1 playback. We felt that it was OK that we heard those channels, but the text says “should not be heard.” We think the language could be “Left Center - Might not be heard” and “Right Center - Might not be heard” So that would be in the text and voice speaking.

3) Not an issue with the DCP part, but we didn’t have all the text on the screen - meaning it wasn’t framed right. We COULD (maybe not) add a scope frame around the border to let folks know they are seeing all the pixels. This is turning into a really nice piece of test content, why not make it better.

4) There is a need for test content with a sign language video track as per ISDCF documents.

5) There is a need for a SMPTE object based audio track.


We should test language codes for subtitles at next plugfest. One CPL with only one closed caption (CC)  track. One with two CC tracks (EN and EN-UK). A playlist with first CPL with CC EN, second CPL with CC FR. A playlist with first CPL with CC EN, Second CPL with two CC tracks EN-GP and FR.

Part 3: “Parking Lot” (things that are in remission)


New ISDCF Document: “Delivery of non standard extension content for Digital Cinema” (Dean/Jerry)

Need for an ISDCF recommended practice for what to expect in the CPL metadata. It will point to the appropriate SMPTE documents for the true authority, but it is targeted at general users (exhibitors) for layman language on what is in the metadata. (Steve/Jerry will revisit)

Subgroup to edit / recommend changes for Document 12 - RP for Ingest Behavior - Steve L to lead, Dean B, John H, Mike R, Jim W, Chris W, Bill E “volunteered” to participate.


Event Cinema Automation -

Europe Subtitles burned in … Problem with trailers - Readdress after move to SMPTE has been completed.

Subtitle update - still issue with 4K png to deliver to 2K projector rendered subtitles. DCI errata has been issued clarifying the matter. SMPTE discussion for additional descriptors to add to define PNG sizes. Some edge cases may not be rendered without additional descriptors.


Subtitle RPL - Multiple RPL topic in SMPTE


     -Measurement of 3D Brightness - update? No solution seen? Is there anything that we can do in this area? Let Peter Wilson keep moving forward.
