About MPEG Transport Stream (TS)
An MPEG transport stream (TS, MTS, M2TS) is the container used for digital TV broadcasting and Blu-ray. It is built from small fixed-size packets that tolerate transmission errors.
TV recordings, AVCHD camcorder files (.mts), Blu-ray discs (.m2ts) and HLS streaming segments.
The packet structure adds overhead, and many editors and phones do not open TS files directly.

Why won't my media player open the .ts file I recorded? A transport stream is written for broadcast, so many players expect a renamed or converted container before they accept it.
About Opus
Opus is an open, royalty-free lossy audio codec standardised by the IETF in 2012 (RFC 6716). It handles both speech and music well, from very low to high bitrates.
Voice and video calls, WhatsApp voice messages, WebRTC, and the audio track of WebM videos.
Opus always decodes at 48 kHz, and some older players and devices do not support it.
Why convert voice recordings to Opus? It stays clear at very low bitrates, so calls and dictation shrink dramatically without becoming hard to understand.

- The soundtrack of the TS is re-encoded as Opus at the default settings, so it is close to the original but not bit-identical.
