I have worked in similar videos before, mostly for school projects and for wedding and festive videos. In my Videos, I prefer to use motion graphics and animations to explain an idea and use a minimum amount of text(or replace text for voice narration), this is an easy and fun way to share the idea and also helps the viewer to better understanding of the message of the video, avoiding losing the viewers interest.
Contact me if you would like to see one of my previous works.
