This extracts the audio and discards the video entirely. The soundtrack inside a OGV file is typically Vorbis, and it is re-encoded to Opus on the way out.
Expect a much smaller file. Video accounts for most of the bytes, so about 26 MB per minute becomes roughly 1 MB per minute of Opus.
Subtitles do not survive audio extraction, since an audio container has nowhere to store them.
When a video holds several audio tracks, the main one is extracted; alternate language tracks are not merged into the result.
Extracting Opus audio from a OGV video pulls the soundtrack out of the Ogg container and writes it as a standalone Ogg file. The video stream, which holds most of the data, is discarded.
Developed by Xiph.Org Foundation in 2008, OGV carries Theora video and Vorbis audio. That combination sets the upper bound on what any conversion can preserve.
Opus was introduced by Xiph.Org / IETF in 2012. It holds lossy-compressed audio (Opus) and plays natively on web browsers and Android.
After converting your file, you can use Scriptivox transcription services to convert your audio to text. Perfect for meetings, interviews, podcasts, and more.
