What to know
Video to WAV saves the soundtrack as uncompressed 16-bit PCM, which is the form audio editors, transcription tools and sound designers usually want. The audio is decoded from the video once and stored without any further compression.
Sizes are large and predictable. Video audio at 48 kHz stereo is 192,000 bytes per second, about 11.5 MB per minute, so a 10-minute clip becomes roughly 115 MB. Selecting Mono halves that to about 57.6 MB, and a Sample rate of 22.05 kHz with Mono brings it to about 26.5 MB for the same 10 minutes.
Because browsers have limited memory, a full hour at 48 kHz stereo, around 691 MB, may stall on a modest computer. For long footage, extract the section you need in several shorter pieces, or choose MP3 or M4A when listening is the only goal.
The WAV will not sound better than the video did, only bigger. It simply means no second round of lossy compression is added before you cut, clean or transcribe the audio, and you can export a small MP3 at the end.
The usual export name is the video name plus video-to-wav, so scene12.mov becomes scene12-video-to-wav.wav, and the Audio quality menu is hidden because PCM has no bitrate.

- Drop scene12.mov onto the video area of the WAV tab.
- Keep Sample rate on Keep source (usually 48 kHz) and choose Mono if one microphone was used.
- Extract and play the preview to confirm the right track and level.
- Download scene12-video-to-wav.wav and open it in your editor or transcription tool.
Quick answers
How large is the WAV of a 10-minute video?
About 115 MB for 48 kHz stereo, 57.6 MB in Mono, and roughly 26.5 MB at 22.05 kHz Mono.
Why is there no bitrate menu?
WAV here is raw 16-bit PCM, so its size is set by sample rate, channels and length only.
Is WAV better than MP3 for transcription tools?
It avoids another lossy generation, which can help a recognizer, but check the tool's own accepted sample rate and channels.
Why does a very long video fail to extract?
The result must fit in browser memory. An hour of 48 kHz stereo is near 691 MB, so split long recordings into shorter parts.
