Hi Rebecca, This does not pass the sniff test. Materials exchange format is a standard ratified by the SMPTE. If Sony uses a proprietary variant of MXF, then it is not MXF. If product documentation trumps the SMPTE, the EBU and LC, then we are going to need a bigger handbasket. http://www.digitalpreservation.gov/formats/intro/intro.shtml http://www.digitalpreservation.gov/formats/fdd/fdd000013.shtml http://www.digitalpreservation.gov/formats/fdd/fdd000266.shtml Please consider changing the subject line when responding to digests. I am not sure what you are responding to. FWIW, SoCal Code4Lib is having a meeting this Thursday. You might want to join us. http://www.meetup.com/Code4lib-SoCal/events/219653631/ Thanks, Cary > On Mar 3, 2015, at 5:21 PM, Rebecca HG <[log in to unmask]> wrote: > > Hello folks, I'm wondering if anyone else has run into this issue.
