How do I convert an M1V file to MKV with LetsConvert?

On the /video-converter/m1v-to-mkv page, upload your M1V file. Select MKV as the output format. The default remux mode keeps the original MPEG-1 video stream intact and simply packages it into an MKV container, so you can then add audio or subtitle tracks. Click 'Convert' and download the resulting MKV file. For advanced users, enable re-encoding to H.264/HEVC if you need smaller file sizes or broader device support.

Why should I convert M1V to MKV instead of keeping M1V?

M1V is an elementary MPEG-1 video stream with no audio, subtitles, or metadata, so it often fails to play correctly on modern devices and media centers. MKV is a versatile, open container that stores video, multiple audio tracks, subtitles, chapters, and metadata in one file. Converting M1V to MKV gives you a universally compatible file that preserves original video quality, lets you add stereo or 5.1 audio, and supports navigation chapters—without increasing video file size if you remux.

Does converting M1V to MKV lose quality or change the video data?

In remux mode, the MPEG-1 video stream is copied bit-for-bit into the MKV container, so resolution, frame rate, color information, and compression artifacts remain unchanged. The process does not decode and re-encode the video, so there is zero generation loss. If you add audio, it is muxed as a separate track and does not affect the video essence. If you instead choose re-encoding, the video will be decoded and recompressed, which can introduce new artifacts depending on codec, bitrate, and settings.
