If a .vtt file is provided, the video captions will be displayed by default. To close the video captions by default, in the gallery editor, step 3 Options tab, Advanced Options, add the following code to the Data Options input box:


A .vtt file or WebVTT (Web Video Text Tracks Format) file defines the subtitles or captions for video content.

A .vtt file is a text file, you can create the file or edit it with a text editor. An example is as follows:


00:01.000 --> 00:20.000
Wonder Carousel - Responsive WordPress Carousel Plugin

00:20.000 --> 00:40.000
Wonder Carousel is the best WordPress carousel plugin to create WordPress image and video carousel.

00:40.000 --> 01:00.000
Support WordPress posts, custom post types, WooCommerce, images, Mp4 and WebM videos, YouTube and Vimeo.

At the beginning of the file, there is a line WEBVTT, then each paragraph defines the time span and the subtitle. For example, the above .vtt file adds three captions to the video content, from 1 second to 20 second, 20 second to 40 second and 40 second to 1 minute.

For more information about vtt file format, please view the document: WebVTT: The Web Video Text Tracks Format.

Step 3 - Publish the video player

After you have added the video file and the .vtt file to the gallery, click the Save & Publish button and save the gallery. The plugin will publish the gallery and display its shortcode.
