Comparing old versions of Avid to 2018.8 it looks like a lot of meta data text information is now supported when turning on Text on the timeline and using DNxHR codecs. However, one important bit of info is still missing. Framerate of DNxHR media. The framerate is displayed when media is encoded in DNxHD, ProRes, XAVC, etc. But not for DNxHR.

Framerate text display is often critical information during mastering.

Thanks
