    v1 v2  
    11I'm looking to be able to specify the dithering algorithm used on the 10-bit to 8-bit conversion. I tried:
    2 ./ffmpeg -v debug -sws_flags +accurate_rnd+full_chroma_inp+full_chroma_int -y -i /mnt/storage/ProRes_10bit_422.mov -sws_dither a_dither -t 30 -pix_fmt yuv420p -an -threads 36 -vf scale=1920:-1:sws_dither='''a_dither''' mnt/storage/raw_8bit_420_adither.yuv
     2./ffmpeg -v debug -sws_flags +accurate_rnd+full_chroma_inp+full_chroma_int -y -i /mnt/storage/ProRes_10bit_422.mov -sws_dither a_dither -t 30 -pix_fmt yuv420p -an -threads 36 -vf scale=1920:-1:sws_dither='''a_dither''' /mnt/storage/raw_8bit_420_adither.yuv
    33
    4 ./ffmpeg -v debug -sws_flags +accurate_rnd+full_chroma_inp+full_chroma_int -y -i /mnt/storage/ProRes_10bit_422.mov -sws_dither bayer -t 30 -pix_fmt yuv420p -an -threads 36 -vf scale=1920:-1:sws_dither='''bayer''' mnt/storage/raw_8bit_420_bayer.yuv
     4./ffmpeg -v debug -sws_flags +accurate_rnd+full_chroma_inp+full_chroma_int -y -i /mnt/storage/ProRes_10bit_422.mov -sws_dither bayer -t 30 -pix_fmt yuv420p -an -threads 36 -vf scale=1920:-1:sws_dither='''bayer''' /mnt/storage/raw_8bit_420_bayer.yuv
    55
    66Both output files are still equal to each other, have the same md5 value.
