SVT-AV1 Vertical 4k video
14 avril 2020, par Dmitry MaksakovI have a vertical 4k video captured on my phone with the following parameters (ffprobe) :

When I try to transcode it to av1 with svt_av1



ffmpeg -i video.mp4 -c:v libsvt_av1 -y output.webm




I am getting

How could I encode such videos ?
