AV1 codec : Dimensions multiples of 2 or 4 ?

[NXYZ]

Hello everyone !

I am looking to resize a video using AviDemux Nightly and the AV1 codec.

My video was mistakenly encoded in AV1 : 16/9 : 1920/1080 pix.
I need to re-encode it in AV1 : 2.35 non-anamorphic.

Calcul of the height : 1920/2.35 ≈ 817.02 pix.

Should I round it to the nearest multiple of 2 ? → 818 pix

Or, given that the smallest block size used by the AV1 codec is 4/4 pix
Should I round it to the nearest multiple of 4 ? → 816 pix

Thanks in advance.
