Intel QSV Hardware Acceleration not found

Hello anybody,

I got the following problem:

My PC (Intel Core i5, Windows 10) does support QSV (Quick Sync Video) hardware acceleration.
In xMediaRecode I can find it and it speed up rendering up to 4 times:

In kdenlive (23.08.4) the acceleration cannot be found.
Message in assistant:
“No hardware encoders found”

Any suggestions how to solve it?

Best regards, Pirx
