Re: [DCP-o-matic] Tested first mayor DCP, few issues

About the sound issue, did you change the frame rate of your film? (e.g. from 25 to 24 fps) Carl, what is the process used to change the speed of the sound? If you use ffmpeg audio filter "atempo", it will cause some distortion in the sound. The algorithm used is very bad. Le 07/08/2014 18:22, Tom Rovak a écrit : I should clarify. The whites from the mid to approximately 80 IRE would be pushed up. The brightest areas of white, roughly 85-100 IRE would not be affected. Same with the blacks. Rough estimations. It would depend a bit on the source. But it is an overall shift. *Tom Rovak - Executive Producer / Sr. Colorist / Post Production Supervisor ROVAK COLORIST SERVICES A Division Of The Annex Studios **Commercials, Feature Films, Music Videos, Long Form* *Color Correction, Dailies, Editorial, Finish/VFX * *trovak(a)comcast.net * &lt;trovak(a)comcast.net&gt; *(815)690-8323 <%28815%29690-8323> Website / Commercial Reel: http://colorist-rovak.com/ <http://colorist-rovak.com/>* ------------------------------ *From: *"Ben Edwards" &lt;list4me2(a)gmail.com&gt; &lt;list4me2(a)gmail.com&gt; *To: *"dcpomatic carlh net" &lt;DCPomatic(a)carlh.net&gt; &lt;DCPomatic(a)carlh.net&gt; *Sent: *Thursday, August 7, 2014 9:44:03 AM *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?
