    Unkown encoder 'hevc_qsv'

    I'm new to this program and can't get it working with my Intel Arc B580.

    I have the current Intel drivers installed. I can transcode H265 QSV with Handbrake no problems.

    A screenshot of what I'm trying to do has been attached. I've tried it with and without the DSP Effect; same result of it failing with "uknown encoder".

    Can someone help me with figuring out how to get this working for transcoding with QSV?

    Thank you!

    This is likely the issue, try running Video Converter as Administrator (right click on dBpoweramp control centre >> run as administrator >> then choose music converter)

    I updated the drivers of my B580 to the newest version (32.0.101.6559), and since then, I can't use the hardware encoders for recordings anymore. When I tried recording, there was an error and when I checked the output tab, all QSV options were completely gone. I was using them before and they...
