Ah ok I understand, you are using the COM interface to avoid licensing conflicts because of the closed source part of the Voukoder Connectors. This way the library is not used directly as shared or static library and does not conflict with licensing. So we need something like COM on Windows on MAC or linux too.

Would it be possible to use Voukoder as a shared library instead of using COM? This way it could be used with mac or linux, or I'm wrong?

If you want detailed performance comparison of hardware transcoding (NVENC) just look here. But keep in mind that this data cheat does not compare performance of one encoding, its comparing how much encodes the GPUs can run simultaneously.

If you only encode one source, the encoding speed between a 2080 and 1660 is pretty much the same.

As far as I can see in the log file it has nothing to do with NVENC I would say, because the vEncoding times are fine.

Frame #112: vRender: 587084 us, vProcess: 10 us, vEncoding: 10886 us, Latency: 598019 us

Whats very high are the vRender times. That's the time Adobe needs to render the frame and send it to Voukoder (NVENC). Something in your Project will cause this I think.

Read more here.

You don't understood me. Media Encoder uses the GPU (CUDA cores) too. You can disable this by turning the Renderer to Software only in Media Encoder.

Turning this to software only helps maybe.

NVENC is an encoder not a renderer and is still used.

You could try to export without CUDA acceleration in Media Encoder. But you need a lot of CPU power then.

I think you mean this ?

What CPU, GPU, Premiere Version, Windows Version and amount of RAM are you using Thomas78 ?

Do you have any idea Vouk ? On my side the exporting with AV1 default settings with 1080p resolutions works fine.

Does the default settings with Av1 work?

You could try to set another profile or unset the maxrate value. Or the frame size of 3840x3100 is the problem. Some options do not work reliable until now.

Can you append to logfile of voukoder?

Could you reproduce this now? If not I can append a video how to reproduce this

Edit:

It seems like this crash only happens with Premiere/Media Encoder CC 2018, with CC 2020 it works fine.

If the source audio is 5.1 channel and if you export it to stereo, Premiere/Media Encoder crashes at the end of the export. I think this happens with all audio codecs (I tested fdk-aac,aac,ac3,eac3). Changing the video codec or container format doesn't make a difference.

What I have also noticed, if you use fdk-aac and enable low level logging Premiere/Media Encoder crashes instantly at the beginning of the encoding and not at the end, if low level logging is disabled it crashes at the end like the other audio codecs.

If you want a better quality you have to increase the bitrate or set a lower cq value. Preset for nvenc should be set to "Slow" for best compression to quality ratio.

Furthermore if you export multiple exports with Media Encoder and an export finished the log file for the next export will be written to the file of the export before AND to a new log file.

You have to download the fdk-aac dll file and put it in the system32 folder of windows az5456 .

You should take a look here.

With Voukoder 4 the log file next to the export file can't be deleted until the NLE is closed.

Oh you're right
