According to the Wiki (https://en.wikipedia.org/wiki/AV1#Profiles)
av1 high profile should support 4:2:0 with 8bit and 10bit, but:

ffmpeg -y -loglevel fatal -threads 8 -i "F:\TestClips&Co\files\test.avi" -map 0:0 -an -sn   -vf zscale=rangein=tv:range=tv -pix_fmt yuv420p -vsync 0  -f yuv4mpegpipe - | aomenc --passes=1 --pass=1 --target-bitrate=1500 --end-usage=vbr --profile=1 --cpu-used=3 --undershoot-pct=0 --overshoot-pct=0 --buf-sz=6 --buf-initial-sz=4 --buf-optimal-sz=5 --drop-frame=0 --kf-min-dist=0 --kf-max-dist=250 --auto-alt-ref=1 --arnr-maxframes=7 --arnr-strength=5 --noise-sensitivity=0 --sharpness=0 --static-thresh=0 --tune-content=default --tile-columns=0 --tile-rows=0 --min-gf-interval=0 --max-gf-interval=0 --threads=2 --width=640 --height=352 --i420 --input-bit-depth=8 --bit-depth=8 --row-mt=0 --cdf-update-mode=1 -o "E:\Temp\18_13_01_6710_01.ivf" -

give me:

Profile 1 requires 4:4:4 color format

also av1 professional profile should support 4:2:0 with 8bit, 10bit, 12bit, but:

ffmpeg -y -loglevel fatal -threads 8 -i "F:\TestClips&Co\files\test.avi" -map 0:0 -an -sn   -vf zscale=rangein=tv:range=tv -pix_fmt yuv420p -vsync 0  -f yuv4mpegpipe - | aomenc --passes=1 --pass=1 --target-bitrate=1500 --end-usage=vbr --profile=2 --cpu-used=3 --undershoot-pct=0 --overshoot-pct=0 --buf-sz=6 --buf-initial-sz=4 --buf-optimal-sz=5 --drop-frame=0 --kf-min-dist=0 --kf-max-dist=250 --auto-alt-ref=1 --arnr-maxframes=7 --arnr-strength=5 --noise-sensitivity=0 --sharpness=0 --static-thresh=0 --tune-content=default --tile-columns=0 --tile-rows=0 --min-gf-interval=0 --max-gf-interval=0 --threads=2 --width=640 --height=352 --i420 --input-bit-depth=8 --bit-depth=8 --row-mt=0 --cdf-update-mode=1 -o "E:\Temp\18_16_01_5510_01.ivf" -

and

ffmpeg -y -loglevel fatal -threads 8 -i "F:\TestClips&Co\files\test.avi" -map 0:0 -an -sn   -vf zscale=rangein=tv:range=tv -pix_fmt yuv420p10le -strict -1 -vsync 0  -f yuv4mpegpipe - | aomenc --passes=1 --pass=1 --target-bitrate=1500 --end-usage=vbr --profile=2 --cpu-used=3 --undershoot-pct=0 --overshoot-pct=0 --buf-sz=6 --buf-initial-sz=4 --buf-optimal-sz=5 --drop-frame=0 --kf-min-dist=0 --kf-max-dist=250 --auto-alt-ref=1 --arnr-maxframes=7 --arnr-strength=5 --noise-sensitivity=0 --sharpness=0 --static-thresh=0 --tune-content=default --tile-columns=0 --tile-rows=0 --min-gf-interval=0 --max-gf-interval=0 --threads=2 --width=640 --height=352 --i420 --input-bit-depth=10 --bit-depth=10 --row-mt=0 --cdf-update-mode=1 -o "E:\Temp\18_16_44_1810_01.ivf" -

give me:

Profile 2 bit-depth < 10 requires 4:2:2 color format

From the looks of it:
Main at least supports:

• 420 with 8 and 10 bit

High at least supports

• 444 with 8 and 10 bit

Professional at least supports

• 420 with 12 bit
• 422 with 8,10,12 bit
• 444 with 8,10,12 bit

-> is the wiki wrong of is this a missing feature or bug in aomenc?

Some reliably info would be nice.
