About MKV and WAV
Matroska (MKV) .mkv
Matroska: an open container that will hold almost any combination of video, audio, subtitle and chapter tracks in one file.
Good for
- Unlimited tracks — multiple languages, subtitles, chapters
- Codec-agnostic, so it holds nearly anything
- Open, well documented, and resilient to damage
Trade-offs
- Browsers will not play it natively
- Many TVs and phones refuse it — the usual reason to convert
- Being a container, contents vary wildly file to file
video/x-matroska
WAV .wav
Raw uncompressed audio samples in a thin container. Exactly what came off the recorder, at roughly 10 MB per minute of stereo CD-quality sound.
Good for
- Bit-for-bit perfect — nothing is discarded
- No decoding overhead, so editors handle it fastest
- The standard working format for recording and editing
Trade-offs
- Very large — around 10 MB per minute
- No built-in tags for artist or album
- Impractical for distribution or streaming

What changes when you convert MKV to WAV
Only the sound is kept
This takes the audio track out of the MKV and writes it as WAV. The picture is discarded entirely, and no conversion back will return it — keep the MKV if you still need the video.
This is a re-encode, not a repackage
Some tools can move a stream into a different container untouched when the codecs happen to line up. We do not — every job here is decoded and encoded again, so the conversion takes time in proportion to the length of the file and costs a small amount of quality even where a repackage would have been possible. In exchange the output is predictable: it plays everywhere, rather than inheriting whatever the source happened to contain.
What your WAV will contain
The output is 16-bit PCM — as uncompressed 16-bit PCM, the format CDs use. There is no quality setting because nothing is being decided: every sample is stored literally. Expect around 10 MB per minute of stereo audio, which is the price of a format that every editor and every piece of hardware will open.

MP4, MOV and MKV are not really video formats
The extension on a video file tells you far less about it than most people assume. Understanding the difference between a container and a codec explains almost every confusing thing about video conversion.

Bitrate is the single dial that decides how big an audio file is and how good it sounds. Here is what the numbers mean, why they are not comparable between codecs, and where the real thresholds sit.
