DNxHR 444 10 and 12 bit Support

Premiere Pro has major issues with DNxHR 444. Regardless, if it's the 10 bit or the 12 bit flavor and if it's wrapped in MOV or MXF. I won't even get into the whole Full/Legal debate, as that is another topic, but you can take a look at this thread, it lays out very detailed explanations of that issue:

As a colorist, this presents a challenge, since for a lot of us who do not work on a Mac, exporting ProRes from Resolve is not an option and not every production has the capacity of handling uncompressed files. Be they DPX/TIFF sequences or even uncompressed MOV wrapped codecs.

To give you an example, I just had a project shot on the Sony Venice in 6k, client wanted to do a roundtrip workflow where I send them the graded shots in 6k for them to online and deliver. I'm sure you can see the problem of trying to render and playback 6k uncompressed media, especially in an image sequence format, for most it's unmanageable.

Presently, Premire Pro just straight up is not reading DNxHR 4444, but it used to. I relied on it to substitute ProRes 4444 and now I cannot. I am that it is not officially supported as it's not listed on the supported file formats page - https://helpx.adobe.com/premiere-pro/using/supported-file-formats.html ;however, I find it unacceptable that such a major and established codec is incompatible with your software.

I urge the Premiere Pro development team to take a look at this issue and fix it as soon as possible, as there is a massive need from countless people who rely on it every day to be able to deliver to premiere users.

The image below showcases that even the properties' interpretation of different DNxHR 4444 favors is incorrect:

• MXF wrapped 10 & 12 bit files are both seen as 10bit
• MOV wrapped 10 & 12 bit files ar both seen as 12 bit.

Below are the correct interpretations by the software Media Info:

This Problem only compounds when trying to deliver files with Alpha to premiere from Resolve on Windows. Again, most productions can't handle 6k DPX/TIFF sequences and DNxHR with Alpha is not supported and does not open in Premiere Pro.
