Video Slider

Hi @ashley_c!

To have a video in the background of your slide, you would need the Pro version of Smart Slider, where on the Style tab of your slide’s settings:

you could insert an mp4 video to the background.

In the Free version you could try to use a Youtube layer and adjust it as an Absolute layer

Just that isn’t really good at certain responsive views, so you should make sure, that in all modes: desktop, tablet and mobile you see the video well.

You can see here how you can check different views:

At your Youtube layer:

you can turn off the controls and turn on the autoplay. You should also mute the video to ensure it can be played on most browsers:
