Subtitles not showing on your MKV? What to check

Check four common causes: track selection, external files, timing and damaged downloads.

The file was never picked up

A supported same-name sidecar beside the video can load automatically. If it was not loaded automatically, add the file from the subtitle menu. Every format it opens is listed on the subtitles page.

The track is switched off, or is the wrong one

A film with several subtitle tracks inside it may open with none selected, or with a forced track that only captions foreign dialogue. Open the subtitle list and pick the full track for the language you want.

The characters are wrong rather than missing

Boxes or question marks can involve the file’s encoding, missing font glyphs or text already damaged in the source. AIX Player reads UTF-8, and UTF-16 with a byte-order mark, so saving the file again as UTF-8, or downloading a UTF-8 copy for the same release, fixes it.

They are there but off-screen

If vertical position has been pushed too far, lines can sit outside the visible frame. Reset the subtitle styling and they reappear.

Where to find a subtitle file in the first place

If the film came without one, subtitle sites carry them for most releases in dozens of languages. The thing worth knowing is that subtitle timing is tied to a specific release — the theatrical cut, the extended edition, the version with the studio logos trimmed. Downloading the file that matches your copy saves you adjusting the timing later. If a site lists several, the one whose name most closely matches your video file is usually the right one.

When they load but sit in the wrong place

Occasionally subtitles appear correctly but overlap on-screen text, or fall into the black bar below the picture where they are hard to read. Vertical position moves them up or down until they sit clear of both. PC subtitle positioning does not guarantee the same placement on the TV. The subtitle-position setting is saved globally.

Checking the file really is a subtitle file

Check that you selected an extracted, supported subtitle file containing subtitle text. Check that the file is not empty; a short forced-subtitle track can legitimately be small.
