I have made DCP which is slightly out of sync - about 3 - 4 frames.
Is it possible to fix it without redoing a dcp?
Preferably by single change in CPL, PKL or other places?
I know it might render the DCP invalid, but a few keystrokes are better than few hours of rendering.
Is it possible to change audio/video sync in s DCP?
Re: Is it possible to change audio/video sync in s DCP?
You could load the DCP into DCP-o-matic, adjust the audio delay and re-make the DCP; DCP-o-matic ought to do that fairly quickly.
Alternatively you could edit the CPL and adjust the <EntryPoint> in either the MainPicture or MainSound to advance that thing. This would then require you to remake the hashes in the PKL and ASSETMAP.

Thanks Carl,
There are two questions and one feature request now:
1. How do I redo the hashes without being a programer.
2. Where do I adjust the delay. In Preferences?
Can you add an interface for adjusting sync to DOM?

You can already do that in DCP-o-matic using the delay option under 'audio'.

The delay is in the Audio tab of the content page. DoM doesn't yet provide any means to recalculate DCP hashes.
Adjusting sync by manipulating EntryPoint is quite a niche feature, I think. There may, at some point, be time to make a tool which manipulates DCPs without any sound/picture coding (adjusting CPLs, fixing hashes, signing, that sort of thing).

Carl - what would happen if you e.g. load a DCP with broken hashes into DCP-o-matic, then (re)create it? Yes, it would be a new DCP, not 'the same', but...

It should work AFAICS. Though it would recreate all the MXFs, I think.
