About the formats
.mp4
MP4 is the most widely supported video format. It plays on practically every phone, browser, TV and editor, usually with H.264 video and AAC audio inside.
.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.
