 An overview over the system FFmpeg 7.x supported QSV pixel formats and profiles:

I think we can concentrate on av1 for now.

does it fail if you add "-profile main" to ffmpeg command line for dv av1 encode?

dv due to it being software codec, so ffmpeg forced to push and convert frames from system memory, as opposed to hdv (hw) = > av1 on-gpu transcode)

No, it doesn't fail:

but claims:
"Please use -profile:a or -profile:v, -profile is ambiguous"

ah, I think it mostly relevant to ffmpeg as cli application.

Now, moving to cingg, does adding 

preset 4

b 1570k

into profile file

fix anything?

you can change loglevel to debug in bin/ffmpeg/encode.opts too, it will produce bugger log, hopefully with more detailed error msg.
