  • Converting dolby vision + lossless audio mkv to higher compatibility mp4 using ffmpeg

    28 septembre 2023, par Infinity

    I want to convert mkv to mp4 for the following reasons.

    


    Mkv files do not trigger dolby vision on an LG OLED A1 but mp4 files do.

    


    Lossless TrueHD with Atmos audio and DTS-HD MA audio are not supported by LG A1 OLED.

    


    I would like guidance on what commands need to be used to to perform a conversion that keeps all original audio and subtitle tracks of different languages and file formats.

    


    I have had some success with a reddit post converting mkv files that have dolby vision and eac3 with atmos tracks to mp4 maintaining dolby vision and atmos data but I lose all subtitle tracks and only one audio track is converted other languages and tracks lost.

    


    I have not been able to find information online regarding going from DTS-HD MA or TrueHD with atmos to eac3 with atmos or any other supported format by LG A1 OLED.
