About the formats
.mkv
MKV (Matroska) is a flexible video container that can hold many audio and subtitle tracks. It's popular for films and recordings, but phones, browsers and editing apps often won't play it.
.opus
Opus is a modern audio codec used by WhatsApp voice notes, Discord and WebRTC calls. It sounds great at low bitrates but many players and editors don't recognise .opus files.
