Just a brief thought on this...
It seems to me that the biggest annoyance of making multiple versions
isn't so much the restriction of a single CPL per DCP, but that the
time-consuming encoding of the video MXF file has to be done anew each time.
Perhaps it'd be possible to allow the user to add already encoded
audio/video MXF files in the same way as they add e.g. a Quicktime? In
that case the first version DCP could be created in the usual way, and
then all versions after created using the existing MXF without having to
repeat the JPEG2000 compression again. This would allow a much faster
method to create e.g. different versions of the same film with audio in
different languages.
Yes, it'd be even better to be able to create DCPs with multiple
playlists, but if that's a difficult feature to implement, perhaps
adding the above would be a quick fix to make versioning easier in the
meantime?
Just a thought...

Hi Carsten,

I have thought about it a bit. It
seems to me that the user interface is
the hardest part: how to represent which content should end up in which
version.
It's possible that a single DCP-o-matic "Film" should always represent a
single CPL, and that there should be some way to link them together to
generate multi-CPL DCPs.
On the other hand, perhaps DCP-o-matic "Film" should be a DCP, or a set of
CPLs. Then you could have multiple playlists in DCP-o-matic which
generate multiple CPLs in the DCP.
Maybe there should be a "Content" tab, in which the content is set up
(crop, scale, audio gain, etc.), then one or more "Playlist" tabs, where
content is arranged into playlists, then a "DCP" tab which sets up the DCP
which will contain the playlists.
Alternatively, maybe we can have multiple "Content" tabs with the ability
to copy content between each one (which will re-use the same stuff in the
DCP).
Any thoughts are welcome. I think it's important that creating a
single-playlist DCP is just as easy after any changes as before.
Best regards,
Carl
