New "QT DNxHD/R" support question

Dear Fellow Editors and Adobe Staff,

I might be going crazy, but what does really this all-new "support" for DNxHD do?

All I've noticed so far is that instead of the full range of bitrate and framerate options that legacy DNxHD codec had,

now all we've got is like 20% of that, no YUV/RGB switch, no alpha settings, legacy codec names (1080p DNxHD SQ 8-bit for 120 mbps, 1080p DNxHD HQ for 185 mbps and so on).

Can someone here confirm that setting export to Quicktime - DNxHR/DNxHD, with "resolution" 1080p DNxHD SQ 8-bit is any good for broadcast?

It's not Avid's fault. Like I said, in the previous version of Premiere, with Quicktime and Avid Codecs LE installed, there was an additional window with variety of presets to choose from, all range of bitrate settings, a YUV/RGB switch, an alpha channel switch, and compression switch.

Now all that's gone and there's confusing new names of presets, no switches or anything.

I can see that the alpha switch and compression switch are integrated into export window itself, but the bitrate setting is locked, and the alpha switch is served with some new, confusing information.

I don't get why would Adobe drop the old presets and replace them with new ones. Why not keep both?

After contacting Adobe staff member I got information that the presets available are YUV, are meant for broadcast, and should work, so I uploaded an episode with one of the presets to the TV station.

They're gonna run a full Vidcheck test on it.

Pretty sure Adobe staff is as curious of the results as I am...
This would be the 18th episode I export from Premiere Pro for this particular show. Previous 17 episodes worked just fine with the old QT DNxHD way.


The previous version of PrPro was built on the Avid codecs ​as they were named at that time.​ Go to the Avid site ... that's all completely changed. And Avid has no comparative info I can find in over an hour of scrubbing & searching their site for the exact equivalents in the new nomenclature.

Avid does NOT show or deliver their codecs like that now. There's nothing on the new listing of codecs list like say, the 220 ... or anything even remotely similar ... anymore. They're all listed on their material exactly as they are now in PrPro. That section of the Avid site that I 'quoted' above is the totality of info about the new codecs.

PrPro merely mirrors the Avid methodology of listing their codecs ... the ​current​ Avid methodology. Which, in my view, sucketh ... here's the best "key" to what the labels now mean I can find, and note the 444, HQX, HQ, SQ, and LB monikers are the key:

And this is the way they are now installed on our PC's ... note the naming?

There is no '220' or other such set of options. Avid has changed the way the codecs are downloaded/installed ... period. We're supposed to somehow know whether we need the HQ, HQX, LB, whatever ... and what that means.

what does really this all-new "support" for DNxHD do?

It allows Premiere Pro to import DNxHD QuickTime files without actually installing QuickTime.

MXF is still the better option.

MXF is not an option in some televisions.

This is huge step back. How is this supposed to work for anyone if you have to render and check what bitrate and color space the newly renamed presets have?

Is this Adobe telling us we should just export media out of Premiere for broadcast rendering in other software?

As I noted, Adobe merely adopted the current naming of the DNxHD/R codecs. Unhandy as that is for us users, that was Avid's brainstorm for improving "our" editing lives. Yes it would be nice if PrPro gave say a parenthetical listing of each options actual settings and I suggest asking for that.

I also suggest going to Avid's site and complaining there. That's the actual source of this ... problem.

The way the DNxHD/R codecs are listed was changed because Avid has changed their own names ... for "simplification" I'd guess.

Here's the page from Avid that sort of explains things ...

DNxHR & DNxHD | Avid

And here's a section of that page ...

   

     Choose from a variety of DNxHR formats to fit your given workflow and overcome challenges:

  • DNxHR 444—4:4:4 color space; super gorgeous imagery, ideal for high-quality color correction and finishing
  • DNxHR HQX—High quality extended; beautiful imagery for color correction and mastering
  • DNxHR HQ—High quality; offers a great balance of beauty at a smaller bandwidth for editorial
  • DNxHR SQ—Standard quality; ideal for editorial
  • DNxHR LB—Low bandwidth; ideal for remote workflows and saving storage; LB 1/4 resolution and LB 1/16 resolution also available for the most bandwidth/space-constrained workflows

Makes it all clear, right?

One time while searching, I actually found a listing of which mbps number versions matched which of the newly renamed versions ... but I can't find that right now. I think in general "X" means 10-bit ... but don't quote this memory on that!
