How to fix Prime Video subtitles out of sync

Prime Video’s captions are delivered with the stream, so there’s no manual offset control. When they drift, the fixes are about resetting the stream and the app.

Step by step

  1. 1

    Restart the episode

    Stop playback fully and start again. A reload often re-syncs captions that slipped during buffering.

  2. 2

    Toggle the captions off and on

    Open the subtitles menu, turn captions off, wait a moment, then turn them back on to force them to re-load in time with the audio.

  3. 3

    Update or reinstall the app

    An outdated Prime Video app is a common cause of caption drift on smart TVs and streaming sticks. Update it, or reinstall if updating doesn’t help.

  4. 4

    Try another device or the web player

    If captions are out of sync on a TV, test the same title in a browser or phone. If it’s correct there, the issue is the first device’s app.

  5. 5

    Report the title to Amazon

    If one specific title is always off for everyone, it’s an encoding problem on Amazon’s side — report it so they can re-sync the captions.

Because Prime Video controls the caption stream, a subtitle file tool can’t fix the app itself. SubAlign helps only with your own .srt/.vtt files for downloaded or local videos.

Prime Video subtitle sync FAQ

Why are my Prime Video subtitles out of sync?

The captions are streamed with the video, and drift usually comes from buffering, an outdated app, or a mistimed encode on Amazon’s side. Restarting the episode, toggling captions, and updating the app fix most cases.

Can I manually adjust subtitle timing on Prime Video?

No. Prime Video has no subtitle delay or offset control. Your options are to restart playback, toggle captions, update the app, switch device, or report a consistently broken title to Amazon.
