About the formats
.avi
AVI is an old Microsoft video format. Files are often large and use dated codecs, so modern phones and browsers frequently can't play them.
.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.
