Maximizing & Embedding

Hey Guys, Kenny Clutch "The Dancing Dad" Here from New Jersey. My question is would you suggest it be ok to present video footage if you have it, during your presentation/talk of a client that has had success in your program? 

For Example, Pat explained take 5 sec on how you met this person and then continue with your content. Could you add a video to the content? Or is that too much for the audience? 

I remember at the conference there were a few live testimonials but just wanted to know how would we work that on a smaller scale.
