    So I can't install previous version of RCX for some reason and in version 40 the Avid codec options for AAF and MFX are MXF DNxHD HQ , etc and not MXF DNxHD 175 etc. I can't find anything online about what these codecs are equivalent to in the 1920x1080 world. I just need to know the MXF 10 bit 175x equivalent...

    Yes I see that- my point is that the only available choices are LB, HQ, etc. Post is requesting 23.976 MXF DnxHD 175x. Which one of those options is the equivalent? Can't seem to find that info anywhere.

    Heres avid's white paper on dnxhd. all the dnxhr info talks about LB, HQ, etc but does not equate it to the old 36, 175 etc and the new version of RCX has taken away those options...

    DNxHR HD codec is a proxy in a high resolution workflow. For HD projects you should still be using DNxHD files. We still deliver DNxHD36 and 115 all the time to editorial. Let me see if anything has changed in Redcine-X.

    I talked about how to convert AVIDs new naming convention to their older naming convention in an older post here:

    DNxHD SQ: 8 bit, 606208 bytes/frame
    DNxHD HQ: 8 bit, 917504 bytes/frame
    DNxHD HQX: 10 bit, 917504 bytes/frame
    DNxHD 444: 10 bit, 1835008 bytes/frame

    For 23.98 frames per second:
    DNxHD SQ is:
    606208 bytes/frame * 23.98 frames/second * 8 bits/byte ~= 116294943 bits/s which is ~ 115 Mb/s.

    So I would say DNxHD SQ @ 23.98 is equivalent to the old DNxHD 115

    Thank you! I was surprised to see the other options disappear. Many post houses (especially larger ones) are slow to adopt new things - understandably when you're talking about updating dozens of perfectly running and functioning systems.

    So out of RedcineX, is DNxHD HQX the asme as 175x but just a different name? Is it the same codec with a different name?
