If you convert the opt sequence to bgr0, then to gbrp, then utvideo is lossless . So those observations above combined with this one suggests the issue is ffmpeg internal pixel format conversions of pal8 sources (12,13,14 were pal8; others were monob and rgb24) to gbrp . If utvideo supported bgr0 like ffv1, then it should have worked "out of the box" too. I suggest you report the issue on the ffmpeg bug tracker

Code:

ffmpeg -i "PATH\ED-30-opt\%05d.png" -vf format=bgr0,format=gbrp -c:v utvideo ED-opt_bgr0_gbrp_utvideo.mkv
