Location of your .vtt file - enter full URL - like https://Example.com/sample.vtt.

You can create a .vtt file by uploading your video to YouTube.

* Upload video to YouTube. Let it finish processing it.
* Don't make it public. Keep it private.
* Edit the video.
* In the menu on the left, click "Subtitles"
* Click on the 3 little vertical dots at the end of the row for any one of the subtitle options (if there's more than one), and then click on "Edit on Classic Studio"
* If you need to edit the captions, click on the "Edit" button to the top/right of the video, and then publish the edits.
* Now, select the "Actions" dropdown, and then click on ".vtt" under the "Downloads" section. There will be other options like .srt and .sbv, but be sure to download .vtt. That is the popular "WebVTT" format and that's what is supported by S3MediaVault.
* Upload this "captions.vtt" (feel free to rename it based on your video - like captions-intro-video.vtt) to your WordPress Media page. Then copy the URL to that file.
* And that's the URL you need to insert in the "URL of Captions File" field.
