    About MTS and OPUS

    MTS: MTS/M2TS files come from Sony, Panasonic and Canon HD camcorders (AVCHD). They are high quality but hard to play on phones.

    OPUS: Opus is a modern, highly efficient codec used by WhatsApp voice notes, Discord, Zoom and WebRTC calls. It sounds excellent even at very low bitrates.
