I don't know the AV1 hw limits, but it will be of interest to try this 
codec with FFmpeg (next year)
https://trac.ffmpeg.org/wiki/Encode/AV1

So far I just verified that the current prebuild FFmpeg 6.0.1 (packman 
repo) on Tumbleweed-Slowroll has AV1 Encoder support:

    ffmpeg -codecs -hide_banner | grep av1
      DEV.L. av1                  Alliance for Open Media AV1 (decoders:
    libdav1d libaom-av1 av1 av1_cuvid av1_qsv ) (encoders: libaom-av1
    librav1e libsvtav1 av1_nvenc av1_amf )
      DEAIL. wmav1                Windows Media Audio 1
