The video editor exported the OMF files from Final Cut Pro and named them, example - Episode 20/634
These files then appeared as Episode 20(with a funny little dot)632 on the PC… Nuendo didn’t recognize this as a file extension… ProTools on the PC had no problem with it.
So, Mac guys, please don’t use any ‘forward slashes’ in your naming schemes please. (that’s if you’re exporting OMF’s for Nuendo on PC)
