|Summary||0001608: Option to add black frames to tail of DCP|
Some projectors, I'm told, can glitch on first or last frame of a DCP when that DCP is preceded/followed by another DCP with different frame rate.
Therefore, I like to make DCPs with a single frame of black+silence at start and end. The glitch is invisible if on black.
At present to do this, I need to playlist a 1-frame long video file after the main content. It would be great if this could be done with a setting in DCP-o-matic instead.
I guess the place for this would be in the "DCP" tab, since spacing at the start or between pieces of content can be achieved by using the Position setting for those bits of content - it's only adding black at the end that can't be done via interface at present.

UI part in 1608
Hmm, another GUI option? Why not just shift the beginning of content by a couple of frames, which is easy to do?
The only server I know of that has issues with this is the long phased out DSS200 (and only some hardware revisions).
I am not sure if it is a good idea to tackle this problem with dedicated GUI options in DCP-o-matic, as there are other means to accomplish it.
This usually is only a problem with preshow content or festival entries. One option would be to add black with existing methods, or, simply rewrap the content to 24fps.
It's easy to add black frames on start of a DCP by shifting the Position of the content. But it's not possible to add them to the end at present, except by manually adding a 1-frame long video file as a 2nd piece of content.
By the way Carl, I've found my own way around this now - programmatically adding a single frame of black to the DCP-o-matic timeline - which works fine for me. So please don't implement this on my account. If you think it'd be useful to others too, great, but I also take Carsten's point about adding complexity to the UI.
Yeah, I think having a short piece of black or silent audio ready for this would be the best way. Personally, I guess I can deal with many more options in DCP-o-matic, but even with the simple/full GUI choice now, we have to think towards the average user. And unfortunately, enabling DCP-o-matic for all DCP features already made the GUI a lot more complex than it was in the early days. The trouble for many entry level users is to tell 'optional' or irrelevant choices from mandatory or important choices.
Personally, I would love to see some 'smart' options within the existing GUI elements. E.g. adding a 'negative crop value' would 'add' black (e.g. for letter/pillarboxing). Negative Trimming under 'Timing' would add black frames to head or tail...
