Help with Video software in Photoshop

[TinpanVA]

So I'm taking a stab at a reef video, I've loaded a bunch of photos and video's and let adobe "build" based off of one of the pre-loaded themes. It's down and dirty and gets the job done, however, it repeats a lot of the photos which I don't like. Is there a setting someone knows of to limit or remove the duplicates? Would I be better off allowing the theme to load, then trying to edit it or just bypass the theme and do it myself?
