Use of Footage to creat a slide display

I believed I had won a solution to this previous, however nonetheless appear to have a query:

I’ve the footage I wish to use for a slide display in one folder in Photos. They’re from a number of other time/date classes.

I wish to load the images from that folder in into Footage and make a slide display with song.

I don’t need a desktop slideshow. I would like as a way to save this slide display and to ship it to buddies.

I have not been ready to determine reproduction the footage from the folder into footage as a gaggle now not one at a time.

Is there some way to do this? It kind of feels like there will have to be.
