What metadata lives inside an MKV
Matroska (MKV) is an EBML-based container, so every piece of metadata is a named element with a type and length. The top-level Tags element holds freeform name/value tag pairs scoped to Segment, Track, Chapter, or Attachment — meaning a single MKV can annotate the whole movie, an individual audio track, a single chapter, or an embedded subtitle font independently. The viewer walks all Tag elements and shows each with its target scope, which is how you spot that a commentary track is mislabeled or that director credits live on one chapter but not another.
Chapters are first-class in MKV. A ChapterAtom carries a start timestamp (in nanoseconds), an optional end timestamp, a ChapterUID, one or more ChapterDisplay entries (title, language), and optional ChapterProcess entries for DVD menu-style navigation. The viewer lists chapters in order with their titles and timestamps, which is the fastest way to verify that a concert rip has correct song markers or that a TV rip has Netflix-style skip-intro/skip-credits chapter flags.
Attachments are unique to MKV among mainstream containers — a single MKV can embed subtitle fonts (so ASS/SSA styling renders correctly anywhere), cover art, NFO files, and even alternate track thumbnails. The AttachedFile element lists a FileName, FileMimeType, FileDescription, and the raw FileData. The viewer enumerates attachments with their sizes and MIME types so you can confirm what ships with the file — worth checking on rips before sharing, because fonts and NFO files may reveal the release group or private tracker name.
MKV metadata FAQs
What are segment tags vs. track tags?
Segment tags apply to the whole movie (title, genre, director). Track tags apply to one audio or subtitle track (mix engineer, subtitle translator). The viewer shows each tag with its Targets TargetType so you can tell them apart.
How do I see embedded fonts and their names?
Fonts are AttachedFile elements with MIME types like `application/x-truetype-font` or `application/x-font-opentype`. The viewer lists them by FileName so you can confirm the subtitle styling dependencies.
Can MKV carry HDR metadata?
Yes — Colour elements on the video track carry MatrixCoefficients, TransferCharacteristics, Primaries, and MaxCLL/MaxFALL for HDR10. Dolby Vision lives in a separate BlockAdditional element. The viewer decodes the base Colour element.
What is the writing application and why does it matter?
The WritingApp element (e.g., "mkvmerge v75.0.0") identifies the muxer. Archivists use it to predict quirks — older mkvmerge versions have known bugs around subtitle timing.
Why do some chapters have start and end times while others only have start?
ChapterTimeEnd is optional. Navigation-only chapters (skip points) usually omit it; explicit segment chapters (bonus features) often include it. The viewer shows both when present.
