Weird, but when I list the encoders via: ./ffmpeg -encoders (where ffmpeg is in cinelerra's subdirectory of thirdparty/ffmpeg-6.1) qsv is not listed that I can see.
There is a longer post "FFmpeg qsv_av1" (enabling qsv hw acceleration over 2 pages!) on Intel's support forum. There might be useful troubleshooting details.

Maybe the poster did not finish the last suggestion, but Page 2 near the end, Intel's moderator pointed at an output error:
https://community.intel.com/t5/Media-Intel-Video-Processing/FFmpeg-qsv-av1/td-p/1528124/page/2
For the above error, this is caused by a recent change in FFmpeg master, unfortunately FFmpeg 6.1 also has this issue.
Could you try FFmpeg 6.0 instead ? Or kindly try this patch:

I am wondering if the news and enhancements of importance to
CinGG/FFmpeg 6.1 users may be outlined, including what is ready now and
expected upcoming next?
Although not exactly as requested, I have updated November News to better outline what CinGG takes advantage of in the 6.1 version of ffmpeg. If you can think of anything I left out as it pertains to Cinelerra, please email that. A lot of the new features are only really relevant on the command line and these are best outlined in many places on the internet already. In addition I have minimally tested new formats of WBMP and HDR and have the ffmpeg/video directory format files ready for GIT checkin.
I have tried testing AV1 capability with little success yet, but will continue to see if I can get an updated dav1d library version update for newer operating systems.
Thank you.
Re: 5, only "NVIDIA NVENC AV1 encoding support" seems to be mentioned.
What about Intel (Arc) AV1 QSV and AMD AMF encoders in FFmpeg?
