    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.

    .flac

    FLAC is lossless audio: it compresses sound to about half the size of WAV with no loss at all. It's the format for music collectors and hi-res downloads, but files are large and not every device plays them.
