Just had a look.  If I set everything to 0 there is a 4 min difference between video and audio, this is not the case when dragging files into Premiere. Maybe I should just reimport everything;(.

Maybe just a display rounding problem. Video is referenced in frames, audio in samples. Carl will probably comment on this. Never used the trim feature with split video/audio content. As this is only for testing, small sync issues shouldn't be a problem, as long as it is correct for the full length version. - Carsten On 8 August 2014 11:23, Carsten Kurz <audiovisual(a)t-online.de> wrote: Am 08.08.2014 um 12:15 schrieb Ben Edwards: time and it did whole film I was doing the same thing and sync was OK.  I did however have to reimport all the media as when I reloaded project it would not work so I deleted all the media and imported. That will be the problem - when you insert video and audio separately, you need to trim ALL files that need to run in parallel with the same parameters. If one is left untrimmed, DCP-o-matic will create a full length DCP with the remaining trimmed audio and video tracks padded with silence and/or blacks. - Carsten _______________________________________________ DCPomatic mailing list DCPomatic(a)carlh.net http://main.carlh.net/cgi-bin/mailman/listinfo/dcpomatic -- Ben Edwards, Video Editor and Cameraman web:www.nkytwig.com mobile:07773 02 44 82 skype:funkytwig twitter:@funkytwig iContact Community Video | Bristol Community Channel _______________________________________________ DCPomatic mailing list DCPomatic(a)carlh.net http://main.carlh.net/cgi-bin/mailman/listinfo/dcpomatic -- Ben Edwards, Video Editor and Cameraman web:www.nkytwig.com mobile:07773 02 44 82 skype:funkytwig twitter:@funkytwig iContact Community Video | Bristol Community Channel
