Only the soundtrack survives: the video stream is dropped, and the AAC audio inside the M4V file is re-encoded as WMA.
The size drop is dramatic because the video stream is where nearly all the data lives. A minute of M4V runs around 90 MB; the extracted WMA is roughly 1 MB per minute.
Any subtitle tracks in the source are not part of an audio file and are dropped during extraction.
The source can carry more than one audio track, for example alternate languages or a commentary. Extraction takes the primary track.
This tool takes the audio track from inside a M4V file, a MPEG-4 (Apple variant) container from 2005, and saves it on its own as WMA. Everything visual is left behind.
M4V comes from Apple and dates to 2005. It usually holds H.264 video with AAC or AC-3 sound, and those streams set the ceiling for anything converted out of it.
WMA comes from Microsoft and dates to 1999. It carries lossy-compressed audio (WMA or WMA Pro), and without installing anything it plays 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.
