Video Gallery --- Will anyone advise me how to start to build

a Video Gallery with scrolling thumbnails. I have been fiddling with the Tutorial aptly named PHOTO GALLERY and XML; more particularly Kirupa" excellent ‘scrolling thumbnails’ expositiion. I want to begin to create a similar Video Gallery. Is this possible? What is the most efficient starting strategy for me to use to get my arms around this. I am not overly competent but I work hard.
