    Hello, I would need a little help. I need a Video conveter that converts Mkv Dolby Atmos (7.1) to M2TS Dolby Atmos (7.1). Everything Iíve tried so far Iíve come up with a maximum of 5.1 sound. I have already tried about 10 different converters but there was no success. That is, I need a conveter that will not monitor the sound and picture quality and the extension becomes M2TS

    Google Translate

    thanks silvo

  4. Can be done by clever FFmpeg-GUI (remux only, no conversion).

    Here the info from a remuxed mkv to m2ts:

    I wonder whether there could be something odd or non-standard about your source video.
    Maybe you can provide a sample? You can cut out a small part of a mkv with mkvtoolnix, leaving audio and video unchanged.

    I downloaded the "Leaf (Lossless-ATMOS)" mkv from your link. Should you import this file in tsMuxer, you'll have a "unsupported format" warning thrown at you, leaving the videostream only shown up in the tracklist. The reason for this is that tsMuxer expects a TrueHD stream (with or without Atmos, btw) that meets BD specifications. Which dictate an embedded legacy AC-3 track in case of TrueHD. The mkv container simply isn't capable of this.
    What you can do is import the mkv in UsEac3To and set the audiotrack output as "thd+ac3". This will result in eac3to generating a 5.1 AC-3 track (out of the TrueHD audio) and it will embed this in the - unaltered - TrueHD + Atmos track (note that this embedded AC-3 track is independent).
    The resulting "thd+ac3" file can simply be added with tsMuxer. It will be approved and BD or M2TS muxing will now go properly.

    A simple remux with clever FFmpeg-GUI does the job.

    Yep, works like a charm also. I never knew that clever FFmpeg could mux TrueHD without an embedded AC3 track into m2ts. Nice!
    Never too old to learn...

    thanks guys now it's just up to me to do it the way it should be if you succeed you have to do it too ... maybe it's my installation of the program or something else.
    Thank you so much for helping SILVO

    Well, both tsMuxer and clever FFmpeg GUI don't need installation.

    Maybe you want to be sure to download the latest versions, including ffmpeg itself (extract in same folder where "clever FFmpeg GUI.exe" is).

    As for tsMuxer, I tend to use the latest nightly build.

    Good luck.
