Thanks for the replies.
Carsten I think the 100% transparent SRT trick would work with no
damage/change to the image. A bit of a faff, but workable. Thank you.
Markus I believe DCP-o-matic is smart enough to not re-encode frames
when you trim. It just throws away the frames you trim off and keeps the
rest without re-encoding. But thanks for the suggestion.
Carl Thanks for implementing this. If it's possible to backport this to
2.12.x, that'd be great. I'll use the test version for this DCP, but
it's something that would have been useful on a few other DCPs recently
so it'd be great to get it in the permanent pipeline when that's possible.
By the way, I saw the changelog for latest test version and there's a
ton of brilliant features in there. The keyboard shortcuts for frame
forward and backwards are particularly appealing (it's the simple
things!). When do you think this is all likely to make it into 2.12.x?
Please don't take that as me trying to push you if it's not stable yet -
the rock-solid stability of DCP-o-matic is a massive asset - just asking...

Hi all,
Now now, play nicely ;)
I've added a button which will be in 2.13.68 if you're in a position to
use the test version (even for just this DCP). It's not tremendously
invasive so I could be persuaded to backport to 2.12.x I expect.
Best,
Carl

Hi Jim,
I have an open feature request for this on Mantis, but you know how stubborn Carl can be
at times ;-)
Currently I think the only way to force reencoding is to do some minor damage - e.g.
cropping a single line. Another less obtrusive option could be to burn-in an invisible
char, e.g. small dot. I guess you can set it's transparency to 100% and still force
reencoding. The timing for that SRT burn-in has to extend from the first to the last frame
so that all frames have to be reencoded.

Hi all.
Is there any way to force re-encoding of a DCP? We have a DCP which has an illegally high
bitrate, and would like to re-process it to re-encode the frames at a lower bitrate.
Usually, where you don't alter the image (crop, colour conversion etc) DCP-o-matic is
clever enough just to repackage the original J2K frames without re-encoding. But is there
any way to force it to do a re-encode?
Or can anyone suggest a workaround? A good way to export to an image sequence and then
re-import that for example?
Many thanks,
Jim
