Interestingly now I’ve reinstalled the ProRes video is showing up in the project but I only have audio, I’ll try re-encoding to Avid DNxHD and see if that works any better.
Well I don’t have a license for that codec but it certainly let me know that in the video window itself in Dorico, so I presume it would work in that case.
I’ll try the H264 codec in the conversion tool I mentioned as a last resort before I go back to what I was using before the issue started.
