I've heard the renderer in AfterFX is not the fastest one. As said before Voukoder can only encode in the speed that the host application can deliver the frames. It is also an RGB > YUV conversion necessary.
And it always depends on the type of the project. For Verendey it was pretty helpful.
Did you find any bugs and issues yet? besides speed?
Please test the updated version and it would be nice to get some feedback back from you. Did you find any bugs? Do you need some more integration into AfterFX? What color depths do you need?
Just realise that changing "Format options" in "Video Output" doesnt change anything from a default x264 (*.mp4) setting. I choose NVENC hevc but when click on it still says x264. When I select *.mov export it still export in *.mp4. I was probably export in x264 because the NVENC hevc option seems not to apply.
This will be fixed in the next version.
I am glad it helps you that much. 
But it is not finished yet. I need to put some more work into it.
What happens if you create a new project, you add the mp4 file and try to render it with default settings? Does that work?
This is planned. I've had a similar request for h264, too.
I just need to find out how to do this correctly.
Yes, i think it is a good one. Noar, can you provide the vector files to me?
Well, I sent you a 2.0.9 preview so the next official voukoder release will have this issue fixed.
Looked at it but some assets are missing there. It might be related that the audio is 4 channel audio.
But if i drag the video and wav in a new premiere project I don't have any issues when exporting it.
Yes, there are quite some reports that R2 is slower, but I still don't know why. On my systems i can't find any performance issues. You might also look at this to investiagte the issue on your system:
It's already in the sources, but everything needs to be tested. It will take some time for 178 filters.
Feel free to participate here: As a user I want to have easy to use presets for each encoder available to use.
Meanwhile I also prefer the Handbrake style approach.
Don't define presets by some settings, define them per use-case (i.e. "YouTube Recommenended", "YouTube GPU accelerated") Just some quick thoughts
Okay I will send you a custom voukoder version that produces a special logfile. To actually see the logfile generation you need a tool called WinDbg.exe. This is also included in the zip file.
Instructions:
1. Close all programs and unzip the ZIP file
2. Copy VoukoderR2.prm to C:\Program Files\Adobe\Common\Plug-ins\7.0\MediaCore
3. Start WinDbg.exe
4. In WinDbg select "File" > "Open executable"
5. Select "C:\Program Files\Adobe\Adobe Premiere Pro CC 2019\Adobe Premiere Pro.exe"
6. Premiere now gets started and additional logging appears in WinDbg
7. Now reproduce the error with both X264 and NVENC_H264
8. Save the WinDbg logfile and send it to me / forum.
9. Close all programs
This looks strange. The only obvious thing is that you don't have much RAM available. Do you have any chance to try this on a different machine (with more ram)?
You can find all old releases here: https://github.com/Vouk/voukoder/releases
There is also some knowledge about voukoders speed and performance: Voukoder Performance Analysis
Can you send me a small sample clip i could try to reproduce it with?
Doesn't seem to work for me, either.
Looks okay on your sides. It is limited by CPU or GPU in both case.

Did not find a memory leak yet. After Effects is just using as much RAM as possible for the export. Just like Premiere does.
Same happens with the builtin AVI exported as far as i've seen.
You can not compare this!
