Dear Vouk, has this issue been resolved or is there something you need from Blackmagicdesign beforehand?
I have been tripping over this problem quite a while now, because I don't want to degrade the audio to 16bit and with some workflows 32bit integration isn't working in other tools.
ProResLT is 8bit depth. However, there are no 8 bit choice inside of Voukoder plugin setup, 10 only.
No, all ProRes variants are 10bit or more. From 444 upwards they are 12bit.
Would it be possible to make the aspect ratio user changeable in Voukoder like in AMCDX Videopatcher?
Per default it could set 1:1 but advanced user can override this by their own setting.
ProRes HQ 422 is always limited range, afaik.
Per default color metadata for HD should be rec.709, but changeable if needed.
For SD PAL:
Primaries = BT.601 PAL
Matrix = BT.470 BG
Transfer = BT.470 BG
While the differences between rec.709 and rec.601 primaries aren't huge, there are colors which can change drastically like saturated reds and greens.
For SD NTSC:
Primaries = SMTPE 240M
Matrix = SMTPE 240M
Transfer = SMTPE 240M
I was using Voukoder to output AE treated PAL DV avis to ProRes MOV.
The input files are either PAL 4:3 720x576 or PAL 16:9 720x576.
Normally AE does tag its output files correctly, however when using Voukoder 8 (or earlier) it does neither tag the pixel aspect ratio nor any color metadata (color primaries / transfer functions / matrix coefficients).
You can see this with AMCDX Videopatcher where you can add those meta data afterwards.

Perfect! Have a nice day off 
Vouk, can you compile me a list of your SDK questions so I'll can try to contact and send them to the Resolve product manager directly?
There is also a dedicated part for developers on the BMD forum:
https://forum.blackmagicdesign.com/viewforum.php?f=12
But answers are given only quite irregularly.
That's super great
Is there anything else I can do to help here?
That would be very surprising, because currently Mainconcept is working on an encoder for Resolve and I can't imaging that they wouldn't have brought this up as a problem.
The most sought after feature is the ability to export ProRes. With MOV and MXF OP1a as supported containers. Progressiv and Interlaced options. With up to 16 mono audio channels for broadcast needs.
With ProRes 444 and above bit depth should support 12bit (atm Voukoder seems to use 10bit only), and alpha channels with ProRes 4444.
And having x264/x265 options would be great too. Currently h264 output from Resolve is ok, but not great and lacks settings and quality when outputting h264 as the end file format.
I think those are the most important features people are looking for.
Personally for me ProRes is by far my number 1 on the wishlist.
Vouk is such a generous developer so it was a no-brainer
Have sent the License via WeTransfer to you.
PW for the archive has been sent via Email.
Could be. So you're saying I need to buy a license?
I am willing to lend you a license I do own. I have three Resolve licenses (2 dongles and 1 activation key), but only use 2 currently.
(we have been in Email contact (in German) when I tried to lay a direct contact to Resolve's product manager to you).
L+R+C+LFE+Ls+Rs is the official standard layout nowadays for surround.
I think Adobe has changed this in CC and above to reflect the new standards.
