I think it probably would. The original reasoning was to spot if the end
of a previous encode had been corrupted by a crash / power-cut or
whatever. On reflection it seems more sensible perhaps to work back from
the end of the existing data and find the first frame that has the correct
checksum, then continue the encode from there.

Hi Carl,
Re: Sound Sync.
I'm using 1.76 which I've just realised is not the latest.. in the
timing tab I changed frame rate from 25 to 24 and I believe DCP-o-Matic
used to say, audio re-sampled to xxx, but it does not now so I must be
changing the wrong value.
Any ideas? Thanks, Kevin.

Yes.
Best,

Hi there,
can anyone explain these messages to me?
Fri Feb 20 10:33:51 2015: Job: Computing image digest
Fri Feb 20 11:31:54 2015: Job: Computing audio digest
Fri Feb 20 11:33:35 2015: Wrote 46158 FULL, 143758 FAKE, 26 REPEAT; 25 pushed to disk
Especially the last one.
Many thanks in advance!
Cheers,

I'm having an issue with sound sync. Input file is an AVI at 25fps and I
set DCP-o-Matic to output 24fps (our projector can handle 25fps ok but
there is a visual glitch when the frame-rate changes).
The problem is that although the image does run at 24fps the audio
continues at 25fps which obviously causes it to be wildly out of sync.
Am I doing something wrong?

I mentioned before that I like the way DCP-o-matic shows the essential processing options below the content tab, so that there is a quick overview about what happens during the conversion with regard to scaling, aspect ratio, audio, etc.
Wondering wether we could add a full set of these details below the DCP tab - as there is more than enough space there, and some of the DCP tab options are relevant to these. Also, the DCP tab should normally be the final stage before one hits 'Jobs -> Create DCP', so I think it would be good to have an overview over all essential processing there before one finally hits 'Make DCP. One could even an another 'Make DCP' button there.
In a later release, I also think it would be more useful to include the 'tips' or hints there, possibly behind the specific parameter causing the warning/hint. I think 'Tips' will be easily missed as it has to be called manually.
e.g. something like:
Content frame rate is 25 fps -> Warning Icon, Click and 'Your DCP frame rate 25fps may cause problems...' appears.
Same for audio issues, DCP bandwith, etc. This would add to my idea from above for a full overview of most essential aspects of the DCP creation.
And: I brought this up earlier, but Carl has a different opinion on this: I still think the scaling method should go under the content tab and has to be settable content-specific. I don't think it makes sense to have a choice of different scaling methods, but only 'global'. The only reason to choose different scaling methods should be content-related. Another reason: Scaling method is not a DCI/DCP specific parameter, unlike all other parameters under the DCP tab.
