What’s Causing My Subtitles on Amazon Prime Video to be Out Of Sync?
As reported by numerous users, prime video subtitles do not sync with the video due to problems with low bandwidth internet and minor application glitches, which I discovered while troubleshooting and researching the problem.
It happens mainly while watching prime video on smart TVs, such as Samsung and LG, or streaming devices, such as Roku and Apple TV, In addition, it does not appear on the prime video app on Android or iOS.

The following are the most common reasons why Prime Video subtitles appear out of sync:
- A minor glitch in the application
- Low bandwidth or not fast enough internet
- Home Theater not set up correctly
- The audio and video tracks in the file are not correctly formatted/synchronized
Having identified all possible causes, let’s proceed to the solution for out-of-sync subtitles.
How To Fix Prime Video Out Of Sync Subtitles?
As you saw above, there are several possible reasons why Amazon Video captions appear out of sync. To fix this issue, it is not rocket science and can be done easily by following a few steps as outlined below.
Here are the steps you need to take in order to fix a Prime Video subtitle that is not synched up correctly.
- Proper Power Cycle
- Reinstall Prime Video
- Inspect Soundbar or External Audio
- Configure Subtitles Manually
Power Cycle
First and foremost, before progressing to further troubleshooting, ensure that it’s not a minor glitch that’s causing the subtitles to be out of sync.
Often when you’re streaming, your device stores the data that regularly syncs with the prime video app, and sometimes it gets glitched through intermittent internet wifi or through some internal data conflict, and this can be easily resolved by performing a proper power cycle.
In this case, I’m referring to not just unplugging the power cable and plugging it back in right away, but instead waiting for 2 to 3 minutes before reconnecting the cable. You should do this with your device, as well as a wifi router.
Sometimes in a hurry, we miss the correct process, so make sure you follow those steps one by one in order to fix it in the first attempt.
Reinstall Prime Video
If your app is outdated or corrupt, you may also have issues where the subtitles don’t sync correctly and either come early or are delayed by a few seconds.
That is why you should always update your app, and to do so I recommend uninstalling and reinstalling.
By manually reinstalling the app, the latest version will be installed on your device just like when you update the app manually from the app store.
Inspect Soundbar or External Audio
If you are using an external audio device, such as a Soundbar or Home Theater, it is possible that they are not set up correctly, or have too many cables/connections connected, which may delay subtitles.
If this is the case, you will have to check the audio settings of your device and align them with external audio.
Configure Subtitles Manually
When all the above steps have been carefully checked and followed, but you still don’t get the problem, then the subtitles may not have been set up properly and this is what is causing your subtitles to fall back.

In this case, you can play around with the Prime Video subtitle settings and see if the subtitles are displayed properly.
Switch Between CC and Subtitles
You may need to switch to CC (Closed Captioning) and then disable subtitles again.
As a result, you can determine if closed captioning has fallen behind too and focus your troubleshooting accordingly.
Toggle Subtitles On/Off
Subtitles can be disabled and then enabled again, which may temporarily resolve the issue, but if the issue is internal, the subtitles will revert back to normal and go out of sync.
Configure Subtitle Display Settings
A further way of figuring out the source of your subtitle issue is to adjust the size and font of your subtitles.

By selecting the accessibility tab in the options menu, you will be able to access Subtitles & Captioning.
As sometimes while tweaking these settings the subtitles get perfectly synched. So, try configuring each feature and testing if the issue persists.
Wrapping It Up
After reading the above guide, I hope you will be able to solve the Amazon subtitles out of sync issue on Prime Video. If, however, after applying all those steps, your Amazon subtitles are still out of sync, you might need to get in touch with the support.
As a quick recap, the subtitles on your Prime Video might not be synchronized due to minor gimmicks, low bandwidth, or outdated apps. Here is what you should do to fix it.
- Power cycle your device (Smart TV, Roku, Apple TV, Firestick, etc)
- Reboot your router wifi
- Reinstall the Prime Video App
- Tweak subtitle and closed caption on prime video
