Just in case anyone is searching for clarification as I found confusing, contradicting information, to get Vegas Pro 20 to read Avid DNxHR on Windows 11 Pro, you must (1) install QuickTime 7 from Apple (2) install most recent and (3) turn on deprecated QuickTime feature in Vegas Prefs. I tried first just deprecated, then just Avid but no go, you must do all three. IMO, it's one of the many reason V20 Pro is not ready for serious use and despite my many years of it being my primary NLE it's now just a utility program as I've moved to Resolve for NLE and mixing three years ago.
