user1950: I'm using Avid DNxHR HQX as an intermediate codec to go from Resolve to Premiere, but I can't find a viewer that will play it. 
MPC-HC, MPC-BE, MPDN, Windows Media Player even the dreaded quicktime player all refuse to play it. The only thing that works is ffplay.
Anyone know of a player that can handle this codec yet?

user14504: Here is the link to the White Paper on the codec.

user1871: Potplayer plays the HQX HR file I generated using ffmpeg. You have to tell Potplayer to use ffmpeg's MP4/QT demuxer by setting Preferences -> Filter Control -> Source/Splitter -> MP4/QT to FFmpeg MP4 Source/Splitter.
