Thanks for taking a look at this.
I’m on my 2015 MacBook pro Running Sierra (OS 10.12.4). I have a variety of software installed (I’m mainly an Avid user) but also recently installed RED’s viewing/transcoding software (Tether, Viewer, Cine-X Pro). However I do have both Quicktime X (10.4) and 7 (7.6.6) installed


and as I say installed FCP7 just the other day. Any idea why it can’t see the correct codecs?
