Now it works almost as expected

The first few attempts were unsuccessful, but now it seems to work almost as expected.

At first the converter started for a short time and stopped immediately, the file was only a few KB in size afterwards.

The problem seems to have been the NVIDIA Studio driver.
I switched to the game driver and now it works.

The graphics card (RTX2070) is used to 95%.
But the Ryzen only to 20%.
(maybe more CPU power is not needed?)
fps:4,6

Thanks for the feedback. The cpu demand is pretty light with a strong gpu, I have noticed this too with a 2080.
