How can I see which MXF segments a VF DCP actually plays

[barcud]

Dear community,

I received an (IOP) DCP to work with (creating VF files, etc.). Sorry for the beginner question. I was given a note saying that this DCP already has a VF implemented (a new end credits version).

So I have the full film MXF and an additional MXF containing the new end credits. It seems that DCP-o-matic uses the corrected version, but where can I check that the new end credits MXF is actually being played?
(I am using the latest version of DCP-o-matic.)

Is there somewhere a reference list showing when it “switches” to the corrected MXF?

Thank you.
edit:

In the meantime, I downloaded EasyDCP — (the OV was also made with that.) The demo mode allows opening DCPs. And yes, there it is clearly visible in timeline mode that it uses the modified end credits version. In DCP-o-matic, this is not visible in timeline mode.

Also, in EasyDCP I can see that the DCP is split into reels (I don’t see this in DCP-o-matic either). What is actually the purpose of reels? Is it some kind of separation to make playback easier?

Until now I only received OVs exported from Resolve; those were not split into reels and worked perfectly. Should I aim for a reel-based workflow, or does it not really matter?

You can check that from the composition list or, as it is accustomed to be described "CPL" file. It's an XML file that (often enough, but not always) includes in its filename the name of the DCP.

It is up to you. It does make a difference whether you work with VFs that add/remove/edit material like in this case you mention.
If, for instance, your job is to add subtitles, or an overdub and also add an animated logo at the beginning (like the ones of MEDIA, or of a distribution company, etc. etc.) It makes sense to work with reels, so you don't need to re-create the whole thing.

Mind you, working in reels with DCP-o-matic means destructive editing, as things stand.

From the timeline, I can perfectly see that a DCP (OV) is in reels. Could it be that in your case you have a relatively short reel, that can't be seen?
Or could it be that you have chosen "Single reel" instead "Split by video content" on the DCP tab, on the "Reels..." menu?
In that case, you can see (if it is possible) the different reels on the video or audio, on the timeline, but not on top, where there are arrows to signify the beginning and end of each reel.
