    What changes when you convert MPEG to MKV

    • This is a full transcode rather than a container swap, because MPEG-1 is not one of the codecs MKV carries. Every frame is decoded and re-encoded as H.264.

    • Expect the bitrate to move from roughly 5.5 Mbps to about 24 Mbps at 1080p, and file size to follow.

    • MKV dates from 2002 and is not natively supported by modern browsers, so plan on a desktop media player for playback.

    About MPEG to MKV Conversion

    Converting MPEG to MKV moves the video from the MPEG-1/2 Program Stream container, introduced in 1993, into Matroska, which arrived in 2002. Whether the picture is re-encoded or copied across depends on the codecs both containers accept.

    Developed by MPEG in 1993, MPEG carries MPEG-1 or MPEG-2 video and MP2 or MP3 audio. That combination sets the upper bound on what any conversion can preserve.

    MKV was introduced by Matroska.org in 2002. It carries H.264, H.265, VP9, or AV1 video with AAC, FLAC, Opus, AC-3, or DTS audio and plays natively on Windows.

    After converting your file, you can use Scriptivox transcription services to convert your audio to text. Perfect for meetings, interviews, podcasts, and more.

    MPEG to MKV: common questions

    Will I lose quality converting MPEG to MKV?
    Some quality change is expected whenever the video stream is re-encoded. Keeping the bitrate at or above the source level keeps the difference hard to see.
    What file size should I expect from the MKV result?
    Size follows bitrate: roughly 5.5 Mbps for MPEG against about 24 Mbps for MKV at 1080p.
    Is MKV widely supported on phones and browsers?
    Playback is restricted: MKV has native support only on Windows. It is a specialist format rather than a sharing format.
    Are subtitle tracks kept when converting to MKV?
    They can be preserved, because MKV supports embedded subtitle streams.
    Is this converter free, and what happens to my file?
    Yes, it is free. Your file is uploaded to our servers only to make the conversion, it is never published or shared, and the download link expires after one hour.
