The only way to do this currently is to create a custom slider using either subpages or tagged pages within a for loop. IE {for page where tag= "customSlider"} then inside the loop pull in the fields from those items to generate the content of the slider itself. It requires a good bit of html, jquery and liquid experience though.

Using this model though we’ve been able to put any type of content in a slider including video, forms, complex formatted content and combinations of these.

But I’d advise against putting video in the slider unless you also control the player with add’l scripts to pause the cycle or player while playing or you could have an hidden video running with no way to stop it till it comes back around.
