Subject: [DCP-o-matic] Tested first mayor DCP, few
issues
So I managed to create a DCP of the first 30 mins of
the feature I am DCPing and get it on a ext3 drive.
Ingested and plays fine but there are a few problems.
Firstly the audio is pooping in some places, We have a
Dolby CP750 and setting it between 3.5-4 seems about
right for this DCP. This is very low so I guess I have
made the DCP to loud but the popping surprises me, is
this normal if the DCP is too loud. Looking at the
audio graphs in DCPOMatic it looked like it was peeking
about -12 db. I guess the best thing is to use the
level calculator and make 3.5 come out as 5. The 5.1 is
mixed to 0db and I had a -1db audio tweek in DCPOMatic.
The other issue is that there seem to be some blown
whites. I have been trying to find out what the grading
was set up for but used 2.4 as they are being non
responsive (I have been told it is Rec.709). What
effect is using 2.2 or 2.6 going to have. If I go to
2.6 am I correct in thinking the image will go darker.
The thing is there are some very dark scenes. My
understanding is that at the ends of brightness (very
dark and bright) changes in the gamma curve used have
the least effect. i did ask if the whites where ever
meant to be blown (its a found footage mockumentery) and
the answer was no. Any advice?
Regards,
Ben
