Hello,
I get the following warning on the validation of a my DCP: "The LFOC marker is {x} instead of 1 less than the duration of the last reel."
The DCP is based on an OV, which I also imported the project markers from and then I added an 8 second extra credit video which was not present on the OV. The DCP is splited in reels by video content (based on the OV) but the extra credits I added was merged with the last reel for being too small.
The duration of {x} is exactly the duration of the last reel without the extra credits that I added.
So I have 2 questions:
1) Is it possible that on some servers the playback will stop on the LFOC which means that my extra credits will not be played?
2) How can this be prevented? There is no way to change LFOC as I assume DCP o matic will automatically set it to the correct value but in my case it didn't, maybe it's a bug?
Thank you

1) There is no practical use on the playback, set by those markers.
The only trouble I could imagine is a setup where the TMS (Theater Managing System) takes that into account, in order to turn on the lights or similar, when it creates an SPL, Show Play List automatically.
What is important is the entry points and the durations of the reels on the CPL. And the one doesn't affect the other.
And that ineffective presence of the markers is probably the reason that DCP-o-matic may be checking the position of the markers, but doesn't interfere in the human entries.
Is it, indeed?
What do you say, Carl?

You should be able to edit LFOC Marker in DCP-o-matic.
It is very unlikely to happen that it would cause issues, however, it depends on how this DCP will be distributed and played. Some TMS may use this marker for certain actions and TMS users may be used to simply accept them as correct. I doubt that any of these actions would be really problematic, though.

Re: Wrong LFOC marker - Will DCP playback stop there?
At the moment LFOC (and FFOC) should be written automatically as the first and last frames of the DCP by DCP-o-matic. You can't alter them manually, because SMPTE Bv2.1 says they must exist and must be at 0 and nframes-1. Why we even bother writing them is left as an exercise for the reader.
If DoM is warning about a LFOC marker in a DCP it made, there's a bug somewhere!
