What codec do i need to view mxf-files converted to mxf.mov-files by Raylight in Quicktime on my mac? Is there also a codec that will work for importing mxf.mov-files into premiere cs3 for editing?
You need the DVCPROHD components that install with FCP 5 or later versions.
At that point if you can see the video in Quicktime player then you will be able to edit in Premiere as well.
In about a month we will release a Raylight codec for Mac for people who do not have FCP.
