[FFmpeg-user] Encoding Settings

Unfortunately dropping the dashes resulted in the same results as before when I had the leading dashes.

Below was the result.

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

ffmpeg -i input.mkv -profile:v high -level:v 4.1 -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:mbtree=1:bitrate=2500<tel:+442500>:ratetol=1.0:qcomp=0.60:qpmin=0:qpmax=69:qpstep=4:cplxblur=20.0:qblur=0.5:vbv_maxrate=31250<tel:+4431250>:vbv_bufsize=31250<tel:+4431250>:nal_hrd=none:filler=0:ip_ratio=1.40:aq=3:1.00 -map_chapters -1 -c:a aac -ac 6 -ar 48000<tel:+4448000> -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

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

The below do not even show up in encoding settings in MediaInfo or on FFmpeg









I really appreciate your help :-)

That means it works now?

Okay, I just wanted to point it out. ;-)
