My test with own build Cingg to use my system ffmpeg 7.1, shows that 
hdv.m2t and hd.mov rendering with high (or 1) profile to av1_vaapi.webm 
works on Arc A750, when tweeking the av1_vaapi profile as follows:

change "profile" to "vprofile" and rc_mode from "QVBR" to "CQB" (both 
according to ffmpeg output)
(just profile=main also works, possibly due to main is default?)
-------------

# Nvidia 4000+ series (better nvenc/vdpau)
# AMD Radeon 7000+ series
# Intel Xe2, Arc+ series
cin_hw_dev=vaapi
g=30
vprofile=high #(main, professional)
rc_mode=CQP

Then this seems to fit with
