I think so, I can send you a Cinesend download link if that works for you? Just to note, the INTEROP DCP was provided by a third party, and I'm just trying to convert it to SMPTE.

Open subtitles; I wanted to see if DCP-O-Matic would actually read and display the subtitles over the video image during playback, since it wasn't including them in the resulting SMPTE package.

DCP-o-matic would read AND convert them into SMPTE/MXF subtitles, instead of failing to integrate them into a SMPTE project. One could call this a bug or mistake, or not.
The INTEROP DCP is divided up into reels. Would that affect the complexity of using this approach?

A little bit, yes. However, ultimately, DCP-o-matic should support a straight conversion, as it's a typical use case.

Thanks for sending the DCP!

The freeze on selecting "view subtitles" is a silly mistake that I have fixed locally and will add to a release soon.

The choppy playback is just (I think) because you are previewing a DCP and this is a computationally-intensive operation that is unfortunately slow on a lot of computers.

That message about "not being able to reference" doesn't mean that it can't use the subtitles, only that it can't reference them in a VF that you are making. The GUI is not very clear here, sadly.

So, is the best approach to just manually add the XML files from the INTEROP version? Is that correct?

If so, will DOM automatically assign them to the correct reels?

It may be the best or only way CURRENTLY. I don't have the time to play around with this at the moment, but ultimately, DCP-o-matic should probably support a straight conversion incl. all CPL elements.

Sorry, it took a while for me to realise that you are not getting any subtitles in your SMPTE output DCP. That's just a bug - it should definitely work. I'm having a look now.

Ticking "use as" in the subtitle tab, then making a new SMPTE DCP works for me (I get a SMPTE DCP with SMPTE subs). Is that what you are doing? Do you see no subtitle files in the resulting DCP?
