The pricing page for mediaconvert seems to not list the price for transcoding AVC with quality level 'Single pass HQ', only pricing for 'Single pass (speed optimized)' and 'Multi pass (quality optimized)'. Is quality level 'Single pass HQ' not valid for AVC transcoding? The comparison between basic and proffesional tier features seems to indicate that 'Single pass HQ' is only a valid option for HEVC encodes, but creating a mediaconvert job using AVC and setting quality level to 'Single pass HQ' seems to work.
