Below are the settings I used but only some of the settings match

ffmpeg -i input.mkv -x264-params -cabac=1:-ref=4:-deblock=1:-1:-1:-analyse=0x3:0x113:-me=umh:-subme=9:-psy=1:-psy_rd=1.00:0.15:-mixed_ref=1:-me_range=24:-chroma_me=1:-trellis=2:-8x8dct=1:-cqm=0:-deadzone=21,11:-fast_pskip=1:-chroma_qp_offset=-3:-threads=16:-lookahead_threads=4:-sliced_threads=0:-nr=0:-decimate=1:-interlaced=0:-bluray_compat=0:-constrained_intra=0:-bframes=3:-b_pyramid=2:-b_adapt=2:-b_bias=0:-direct=3:-weightb=1:-open_gop=0:-weightp=2:-keyint=250:-keyint_min=25:-scenecut=40:-intra_refresh=0:-rc_lookahead=50:-rc=2pass:-mbtree=1:-bitrate=2500:-ratetol=1.0:-qcomp=0.60:-qpmin=0:-qpmax=69:-qpstep=4:-cplxblur=20.0:-qblur=0.5:-vbv_maxrate=31250:-vbv_bufsize=31250:-nal_hrd=none:-filler=0:-ip_ratio=1.40:-aq=3:1.00 -map_chapters -1  -c:a aac -ac 6 -ar 48000 -ab 224k output.mp4

After the encode is done I checked in MediaInfo under encoding settings and the settings that do not match are:

ref=3 should be ref=4

deblock=1:0:0 and should be deblock=1:1:1

me=hex should be me=umh

subme=7 should be subme=9

psy_rd=1.00:0 should be psy_rd=1.00:0.15

me_range=16 should be me_range=24

trellis=1 should be trellis=2

chroma_qp_offset=-2 should be chroma_qp_offset=-3

threads=12 should be threads=16

lookahead_threads=2 should be lookahead_threads=4

b_adapt=1 should be b_adapt=2

direct=1 should be direct=3

keyint_min=24 should be keyint_min=25

rc_lookahead=40 should be rc_lookahead=50

rc=crf should be rc=2pass

aq=1:1.00 should be aq=3:1.00


The below do not even show up encoding settings in MediaInfo

bitrate=2500

ratetol=1

cplxblur=20.0

qblur=0.5

vbv_maxrate=31250

vbv_bufsize=31250

nal_hrd=none

filler=0


Thank you

    What did you try and what didn't work (command line with complete, uncut
    console output missing)
