Only the soundtrack survives: the video stream is dropped, and the AAC audio inside the TS file is re-encoded as Opus.
The size drop is dramatic because the video stream is where nearly all the data lives. A minute of TS runs around 113 MB; the extracted Opus 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 TS file, a MPEG-2 Transport Stream container from 1995, and saves it on its own as Opus. Everything visual is left behind.
TS comes from MPEG and dates to 1995. It usually holds MPEG-2, H.264, or H.265 video with AAC, AC-3, or MP2 sound, and those streams set the ceiling for anything converted out of it.
Opus comes from Xiph.Org / IETF and dates to 2012. It carries lossy-compressed audio (Opus), and without installing anything it plays 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.
