A common slideshow video is a video that flips through images and often has music in the background. The slideshow can be made more effective with product or business features and unique selling points overlaid on the photos to tell the story with words.
More recently slideshow videos have become much more sophisticated as voiceovers, actual video clips and sting intros and outros can be added to create very media rich slideshows.
Slideshow videos can be displayed on company websites, uploaded to movie hosting sites like YouTube and Vimeo, as well as to social media sites like Facebook and Instagram.
