Does that also work for frame rate converted content?
Say I got content in 23.975fps which by DOM is sped up to 24fps (and audio pitched down) - That would make the duration of the DCP shorter than the extracted subtitles (which I guess are referenced by timestamp?)

Not sure about this but I think there will not be significant difference with subtitles timing, otherwise you can manually fix timing with subtitle-editing software (e.g. Aegisub). I don't know does can encoding software (movavi, freeconvert, etc.) stretch and encode video with saving subtitles. If it does, that would be decision


By the way, have you had success importing extracted VobSub subtitles?
I just made a quick attempt with mkvextract, but DOM does not seem to render the subtitles my screen.

I never used to import VobSub subtitles straight to DoM, first I converted them into SubRip (.srt). If I'm not mistaken VobSub is not text format, it is graphical format, and I'm not sure DoM supports it beyond video-container.

Hi, Christian.
Try to extract subtitles first with MKVToolnix, then add them into DCP as VF.
As far as I know, you can't disable video-track in DCP-o-matic.

Hi
I cannot find a good workflow for making OV and VF(s) from MKV containing audio, video and subtitles.
If I do the OV (containing only audio and video) first I am having trouble adding the subtitles later following the steps described in the manual (https://dcpomatic.com/manual/html/ch17.html).
I do the folowing
  1. New project
  2. Add the OV DCP
  3. Select "Split by video content" in reel type
  4. Checking "Use this DCP..." in both video and audio tab
  5. Add the MKV containing the subtitles (and audio+video from which the OV was made)
Now the MKV is added to the timeline at the end of the DCP (all three tracks).
So now I want to get the subtitles aligned with the DCP.
In the timeline view I drag the MKV content on top of the DCP content and then click on some of the tracks.
Now one of two things happens:
  1. DOM crashes with: "An exception occurred: Programming error at ../src/lib/butler.cc:133 Butler video buffers reached 480 frames (audio is 0)."
  2. DOM refuses to let me use DCP video ad audio: "Cannot reference this DCP: it overlaps other video content; remove the other content"
Okay, my thinking is: I need to remove the audio and video track of the MKV:
  1. In timeline view I separate the DCP and MKV again and remove the MKV audio track successfully (right-click and Remove).
  2. I try to do the same for the video track, but then both video AND subtitle track is removed (and the MKV is removed from the content listing)
So...what is a good workflow to make an OV with no subs and a VF with subs from a MKV?
Cheers,
Christian (using DOM 2.14.2 on Ubuntu 18.04)
