This is a strange one.
VoukoderPro brings all components and dependencies with it in it's installer. It does not need FFmpeg to be installed, it has its own ffmpeg dlls in system32.
Can you share your VoukoderPro logfile %LOCALAPPDATA%\VoukoderPro\logs\*
You can try reporting this issue in the blackmagic forum or ask their support.
Yes, in the NLE you select the format the NLE is sending to VoukoderPro. In VoukoderPro you need to select the actual format you want to have in the file.
You can upsample YUV 420 8 bit to 10 bit, but the visible data is sill 8 bit.
You should even have a shortcut icon on the desktop to start the designer.
So why not have a dropdown menu in the Vegas template itself which allows you to select which pixel format to use? Perhaps accompanied with a helpful hint that if you use YUVA with certain CUDA functions, you're screwed! See below for a mockup of what I mean.
This is how VEGAS Pro works. Some important parameters have to be defined in the template.
What video/picture format does Vegas pass to Voukoder?
I'm using I420, P010 and A410. All uncompressed of course because that's how I can feed the frame into FFmpeg.
I noticed VoukoderPro receives the frame data as 'yuva444p16le', which means you are most likely using this preset:
When using the CUDA pixel format I guess it chooses a pixel format for output that matches the input format. I have not found a way to say 'Once you have finish scaling it encode it as nv12' to the file.
But does it work if you select the 'YUV 4:2:0 (8 bit)' template? This is 'nv12'.
P.S.: I'll also add the 'hwdownload' bilter, but I doubt it makes much sense to upload the frame to gpu, scale it, download it to the cpu, then upload it again to encode it ...
P.P.S: I need to find a way to set the target pixel format if i just send 'CUDA' to the encoder.
Can you paste the voukoderpro logfile (%LOCALAPPDATA%\VoukoderPro\logs\ ...) entry?
What exact encoder are you trying to use?
If it's NVENC try to update you driver software.
That's the most powerful feature of VoukoderPro! Try it with version 0.7.2.4.
Does it work when you start VEGAS with admin rights?
If I correct the file paths so they match my system I got it working:
But I had to run the Designer.exe as administrator. Can you try this?
In the encoder node change the format from YUV 420 to CUDA.
0.7.2.3 brings initial CUDA support!
Note: In the encoder node you need to set the pixel format to CUDA.
Great this issue is solved now! 
Thanks for your feedback.

[11:48:11] Timebase: 1001/60000 (59.94 fps)The first one was started with 23.98 fps. The other 3 ones with 59.94. Voukoder uses the framerate you have set in your NLE. Can you double check it's really set to 23.98 fps in DVR?
This is most likely not a Voukoder issue.
auluswang You might try 0.7.2.1. I'm setting color space, etc there.
What framerate did you select in your NLE? Can you share your voukoder logfile? (See the sticky post in this thread.)
I'm checking this ...
It's available in the downloads section now.
I found a bug: the latest 13 or 12.1, in Davinci studio 18.5beta or 18.5, the data level (Auto, Video, Full) is missing. However, in Studio 18.1.4, it is ok.
Same thing for me. Im using 13.1 Voukoder with the latest connector.
Can you try updating DVR to 18.5.1 build 6 (Latest version) and see if this is fixed? I don't have control over that setting. DVR decides if it shows it or not.
