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.
.webm
WebM is an open video format designed for the web, usually with VP9 or AV1 video. Browsers play it well, but iPhones, video editors and many TVs don't.
