Trouble with Featured Content Gallery

I’m working on a site (https://nezane.org/wordpress/) that uses a theme with a Featured Content Gallery on the homepage. The theme I’m using is https://www.paddsolutions.com/wordpress-theme-magilas/.

I’m trying to make the speed of the slides slower so each slide stays on screen longer, about 7 seconds and I would also like to make the black box under the text descriptions for the slides a little more opaque so the text is easier to read. While looking around I stumbled across a file in the theme called jquery.s3slider.js that I believe could be relevant, how would I adjust this? Or would I have to adjust a php file? Anyway, here’s the code, thanks!
