Whether it's software, cosmetics, toys or clothing, when you have a new product to launch, you want people to learn all about it.  A picture is great, but there's nothing better than a video demo to get people on board and excited about your new offering. Live action, animation, graphics and narration can all be leveraged to demonstrate the product's features, qualities and uses. A video can make users feel comfortable with something new and different, such as this introduction to a new Covid-19 contact tracing app.
