Description (last modified by chrisbgp)

Summary of the bug:

command below works fine on 1080p content, however with 4k content the output of all files are the same and the file size of all outputs is the same as well. when replacing the first prefilter with nlmeans it works as expected. any ideas?

How to reproduce:

% parallel ffmpeg-git-20220526-amd64-static/ffmpeg -y -i chunk-001.mkv -filter_complex "[0:V:0]split[a][b],[a]bm3d=sigma=12:block=4:bstep=16:group=1:estim=basic[a],[b][a]bm3d=sigma={1}:block=4:group={2}:bstep=16:range={3}:estim=final:ref=1"  -c:v libx265 -x265-params limit-sao=1:aq-mode=3 -pix_fmt yuv420p10le -crf 28 -an -sn "bm3dxx/s{1}g{2}r{3}.mkv" ::: 3 6 9 12 15 18 24 ::: 8 16 24 32 ::: 9 12 15 18 24
