  1. Hi, all.

    I want to reencode some blurays that I've ripped (even a personal dvd where my dad hosts a tribute to a friend who passed 20 years ago, I want to send him the file as a surprise) and have just tiny files like the Yify, RARBG ones, using h264 (because I've seen x265 pixelates everything at x400 when you check with virtualdub).

    I've tried to download a few rips of them and I copied the settings:

    VXT

    Code:
    ffmpeg -y -i file.mkv -c:v libx264 -passlogfile file_encoded -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-refs=1:me_range=24:chroma_me=1:trellis=2:8x8dct=1:cqm="flat":deadzone-inter=21:deadzone-intra=11:fast_pskip=1:chroma_qp_offset=-3:threads=32:lookahead_threads=4:sliced_threads=0:nr=0:dct-decimate=1:interlaced=0:bluray_compat=0:constrained_intra=0:bframes=3:b_pyramid=2:b_adapt=2:b_bias=0:direct="auto":weightb=1:open_gop=0:weightp=2:keyint=250:keyint_min=25:scenecut=40:intra_refresh=0:rc_lookahead=50: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:ipratio=1.40:aq-mode=3:aq-strength=1.00 -map 0:0 -pass 1 -an -f mp4 NULL && ffmpeg -i file.mkv -c:v libx264 -passlogfile file_encoded -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-refs=1:me_range=24:chroma_me=1:trellis=2:8x8dct=1:cqm="flat":deadzone-inter=21:deadzone-intra=11:fast_pskip=1:chroma_qp_offset=-3:threads=32:lookahead_threads=4:sliced_threads=0:nr=0:dct-decimate=1:interlaced=0:bluray_compat=0:constrained_intra=0:bframes=3:b_pyramid=2:b_adapt=2:b_bias=0:direct="auto":weightb=1:open_gop=0:weightp=2:keyint=250:keyint_min=25:scenecut=40:intra_refresh=0:rc_lookahead=50: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:ipratio=1.40:aq-mode=3:aq-strength=1.00 -map 0:0 -pass 2 file_encoded.mkv
    YIFY

    But the result is not very very good. I would say it is 70% good, not enough because it is not near to what their rips looks like. I miss a lot of details in my rips when compared, something that doesn't happen with theirs.

    Could you help me? I'd really like to have a result that I'm comfortable with.

  2. My 2 cents: Learn how to filter with Avisynth/Vapoursynth, since usually converting a Blu-ray to 2GB 1080p without loosing isn't really possible, so it's a question of which details to remove and which to keep and this usually is done by filtering.

    x265 pixelates everything at x400
    if you enhance 1080p by a factor of 400 and you don't see individual pixels something is wrong.

  3. I'm not talking about "not losing quality", I'm talking about losing not too much quality, as many encoders groups. I thought that with ffmpeg using the x264 in the right way could be enough. :/ Isn't it?

    And what I was talking about "x265 pixelates at x400" is that:

    This is an x264 frame from a YIFY movie.

    This is an x265 frame from I don't know what group.

    x265 has much better quality, but as you can see, there is that pixelated shape that is not natural at all. It happens with every x265 file that I've checked in my life (that's many, believe me).

    To compare, this is a x400 from an original bluray source that I've ripped myself, it's not the same movie, but it's hyper smooth. Obviusly I know that it's is impossible to achieve that without losing a single bit of information, but it is not pixelated at x400, neither the x264 from YIFY.

    Thanks.
