Marker support missing.. What happened.

[jamiegau]

Did a quick search here and Marker support was said to be present in a test version in an very OLD post.

I cannot find it in the latest version.

This is becoming incredibly important as SMPTE DCPs are now the standard, and people are starting to expect credit offset markers to be present in the CPL. For example, my cinema chain utilises this data today. And it's a breath of fresh air every time I don't have to go and hunt down the credits offset when programming.

Currently I see no way to implement the Markers in the current version of DCP-O-Matic.

Please bring this to the top of the feature request.

In the test version they are in the DCP tab under the "Markers..." button.

Cool,
I have given this a small test and it appear to work fine.
Why is it not in the general release version.

Its been in the test version for years!

I mean, there's a few reasons. Mostly, it just missed the cut for 2.14.x. 2.16.0 will be out just as soon as I can get it ready.

Incidentally: which TMS's and/or playback servers support SMPTE markers already?

[Carsten]

TMS I don't know, but I guess most will by now. Servers: Dolby DSS200/220, all Doremis on current software, Dolby IMS3000, Barco ICMP. GDC I don't know. TMSs usualy receive more frequent software updates than cinema servers.

I just tried creating a test clip on 2.15.135 with a couple of markers:



...but the resulting CPL only has FFOC and LFOC in the MainMarkers element:

Code: Select all

<MainMarkers>
          <Id>urn:uuid:32c839a1-ccda-4dd8-a18a-d067786f4b1e</Id>
          <AnnotationText></AnnotationText>
          <EditRate>24 1</EditRate>
          <IntrinsicDuration>720</IntrinsicDuration>
          <EntryPoint>0</EntryPoint>
          <Duration>720</Duration>
          <MarkerList>
            <Marker>
              <Label>FFOC</Label>
              <Offset>1</Offset>
            </Marker>
            <Marker>
              <Label>LFOC</Label>
              <Offset>719</Offset>
            </Marker>
          </MarkerList>
        </MainMarkers>

Have I stumbled into a bug, or am I simply looking in the wrong place?

[carl]

That's strange, can you send / attach the full CPL and the metadata.xml from that project?

Looks okay for me in 2.15.132:

[Carsten]

Antti - I think your markers have been discarded automatically because they are placed behind LFOC.


720 frames are 30s/24fps - your markers are set at 30s,35s, 50s and 55s.


You should probably always set them from current position (timeline slider), not manually. Better, of course, DCP-o-matic should perform a range check for this.
