Yup. Metadata, incl. Marker is on a to-do list. The trouble is, how to create a usable GUI method. These markers belong to the DCP domain, so should be accessed somewhere under the DCP tab. And we would need to cue to that position in the timeline, then use that position to add markers based on a captured timecode from that timeline position.

Maybe add a third tab under 'DCP', in addition to 'Video' and 'Audio'. I guess it's easy to add this to the GUI and project XML file format, but I guess Carl needs to enhance his dcp/XML libraries to support it? Also, this tab should only be active for SMPTE DCPs.

Under this new tab, there could be a list of different marker types with input fields, and options to fill them either manually, or by picking TC from the playback playhead (as under Content->Timing). Once this list is enabled in GUI and supported in the xml/dcp libs, one could add more standard metadata tags as needed, even add custom tags as allowed per SMPTE CPL metadata spec.

Alternatively, the preview is pretty much the "DCP domain" so maybe some way of setting up markers there? I'm thinking little draggable arrows under the time slider, or something? Maybe you could right-click them and choose "to timeline position." Then we could have some detailed descriptions and editable controls in a new tab like you suggest.

Also are any servers reading these markers yet?

Christie says that IMB-S2 reads FFMC markers, I'll try the test dcp asap.

Yes: Christie IMB-S2 shows markers in details tab

Doremi allows to populate Cue TC from certain marker types. I think Dolby as well. Alchemy/ICMP is about to have it, there is some functionality to add cues from TC already, guess FFMC is around the corner.

While it is true that preview could accomodate these markers, having all these markers would eat up space there unnecessarily.
Also, we need more Metadata with no reference to the preview. So, I guess it would be better to sum all metadata incl markers under a dedicated tab under DCP, and allow to populate those marker fields with a timecode reference from the playhead as with trimming. It would also be helpful if e.g. a click on the Marker timecode would send the playhead to that position in preview. I also guess that general metadata can be extensive once established, so I guess we need a scrollable table. Each entry could have an option to be selected from a drop-down list showing allowed metadata tags, followed by a value field. Some fields could be preoccupied from DCP parameters (e.g. resolution, aspect ratio, language). In the long term, one would probably need ways to weigh DCNC vs. metadata. They should comply. DCP-o-matic's DCNC detail input dialog also takes up that sort of data. Maybe these GUI elements need to be revised at some point. But for now, I think a separate Metadata tab is best.

This is more-or-less done in v2.15.x.
