After all sorts of issues getting the video out the DGI Transcoder tool into an editer (stupid Apple Codecs!) I finally got it going. Think I got the color grading a bit too magenta in a couple places.
Not an amazing video, with no narative etc, just a quick test of some shots from the DJI, and how it looks after transcoing and color grading (I'm far from an expert in color grading):
