I totally agree with Carsten. There's all sorts of tricks you can do, and make a DCP which is valid to the spec, so in theory it *should* play fine. But the more esoteric your DCP is, the greater the chance it'll surface a bug on some projector somewhere.
As the old saying goes: Keep it simple, stupid!

It is possible, of course, but DOM doesn't offer that kind of manipulation currently. I know that some people do this by manually editing the CPL, but it is error-prone, and you need to recalculate the hashes (usually no problem to load the DCP in DOM and recreate it).
What I suggested would probably work using the OV/VF scheme as well. However, every 'unusual' OV/VF scheme - that is, anything that is more than replacing either all audio, all video, or adding subtitles - in my opinion imposes the risc of playout or ingest problems, if you don't have the chance to test it beforehand and do a thorough structural analysis of the DCP created.
The good thing about doing it the way I described it is that the new DCP is complete and does not contain any critical aspects that could break playout.

_______________________________________________I wonder if what Carsten suggest can be done solely by CPL manipulation, by having the reel twice in the AssetList and setting EntryPoint and Duration for each of the two identical reels to produce the content before and after the deleted scene.
It would be kind of neat - That way I guess you would only need to make a VF that could be emailed to the cinema :-)

Hi, is it possible to remove a segment of an existing DCP? I would like to remove 1 minute of video and audio (same scene) from an existing DCP to create a shorter version. If this is possible, how may I do so?
Hi Richard,
there is no direct way to cut a piece out, but to achieve the same, you simply load your content/DCP twice into a project, trim from end on the first instance, and trim from start on the second instance. The new DCP will be seamless after creation, and it won't take much time, as the creation will only be a copy process, not a re-encoding.
You need to set the project/DCP parameters identical to those of the source DCP, though (resolution, container type, frame rate, etc.)
