I am creating a proxy for offline workflow with initially starting with davinci. When exporting for offline edit. Which form of DNxHD codec is comparable to ApplePro Res 422? There are a lot of options to choose from. Can someone please help. Thanks.

Well, you need to be more specific about which type of ProRes you want to compare to DNxHD, but I'll take a guess at what you meant and try to answer.

There isn't always DNxHD variant directly comparable to ProRes 422, because ProRes 422 is always 10-bit and DNxHD is 8-bit in low to mid bitrates and 8-bit or 10-bit at high bitrates.

There are some variants of both that match up almost perfectly. ProRes 422HQ and DNxHD 175X, 185X, 220X are directly comparable as they are all 10-bit 422 codecs with a very similar bitrate.

5 minutes on wikipedia would really help you understand. Don't be so damn lazy.
