  1. Hey, I have muxed a video file using mkvmerge. I do not want the muxed file to contain the info about the bitrate of the video and the encoding settings of the video. How do I remove that information from mkv file?

    Is there a CLI argument I can pass to tell mkvmerge to not pass that information about bitrate and settings from the original file to the new muxed one?

  2. Don't think that will work.

    Why would you want to do this?

    Is the OP trying to hide settings from potential users of his movie ?

    It is a fool's errand. Even though many utilities, like Mediainfo, merely read the heading, there are plenty of other utilities that can scan the entire file and re-create much of that information. I still use these sometimes because headers sometimes don't have the correct information.

    So, if your goal is to hide something, you will not succeed.

  6. 'encoding settings' .. TSmuxer does ... if setting ' InsertSEI' is the option which blanks the x264 encoding settings... you can demux or mux (h264 / ts) and then final remux in mkvmerge ...

    The OP is trying to hide his/her super secret special awesome only he/she knows encoding settings.

    This type of questions comes up every once in a while and it always ends up being someone from the "scene" who wants to hide their settings, for whatever reason. My best guess is prrobably to prevent others from besting or using their super secret special awesome only he/she knows settings and getting their releases out first. Why does that matter? Never could figure that out! Maybe pirate street creed?

    I know that, for starters, we can use Avinaptics to calculate the bitrate back, but the aren't the encoding settings lost forever? Is there a way to regain the encoding settings back?

    Is there a software that has support for x265 codec?

  10. Is there a software that has support for x265 codec?
    To remove all AUDs, SEI and filler from an H.265 stream:
    Code:
    ffmpeg -i INPUT -c:v copy -bsf:v 'filter_units=remove_types=35|38-40' OUTPUT
    source: https://roundup.ffmpeg.org/ffmpeg-bitstream-filters.html#hevc_005fmetadata
    btw. x265 has an option to not add the encoding settings to begin with https://x265.readthedocs.io/en/master/cli.html?highlight=--no-info#cmdoption-info

    Hey, thank you for helping! The --no-info flag worked like a charm.

    Though the other method did not work.

    Code:
    ffmpeg -i sample.mkv -c:v copy -bsf:v 'filter_units=remove_types=35|38-40' output.mkv
    '38-40'' is not recognized as an internal or external command,
    operable program or batch file.
    Thanks again, my problem is solved now. I will pass the flag while encoding itself.

  12. Works fine here:
    Code:
    ffmpeg -i "f:\TestClips&Co\files\MPEG-4 H.265\10bit Test.mkv" -bsf:v "filter_units=remove_types=35|38-40" "e:\Output\cleaned.mkv"
    you might need to update your ffmpeg version also depending on the OS, instead of ticks (') you might need to use quotes (").
