It’s a field for your slide description and it may look like this:

On the screenshot it has a title, subtitle and button and it takes 50% space on the left, but you can set a caption on the right, on a fullwidth slide, with text only, with link or using HTML tags set there <h> and others. To add a link to your slide caption you should go to Enable Caption Link/Button, you can also use your slide as a link here:

The most interesting feature of each slide is  Image Size & Position. You can choose how your slide will look like – where will caption appear, will your slider image be stretched on a full width or will take only 50% of slide space.

You can enable caption on the right/left transparent slider background.

To add a video to your slide go to Video Settings:

Enter your video URL.

There are also General Slider Settings:

Set here your slider animation speed, effect. Turn off/on all captions.

You may show slides navigation, which can be used for manual slides changing:

Pause on mouseover button will help to stop slide displaying manually, you can also show slides navigation or timing on mouseover.

Use Save as button to clone slider settings (if you’d like to have few similar sliders with different pictures, for example).

After your slider is ready, save changes and create a page where you’d like to show these slides. You must set your page options to make the slides shown. Go to “Brilliant Page Slider Options” while editing the page. Tick “Enable slider” checkbox and choose recently added slider:
