Product Videos For E-Commerce
Demonstrating products for Ecommerce websites or Facebook or even Amazon takes creativity and a marketing sense to understand what will sell the product. It is important to display the product in the right context. All product videos should show either in use or a use environment. As far as timing goes, a product video can be both short and long form. Advertising videos with products tend to be short, unless you are going for an informercial style long form video. There are also informercial length, entertaining funny videos that demonstrate the benefits and value of the product, while entertaining the audience.
Sometimes product videos are how to videos. How to use the product, or how to set up the product.
On one hand you are marketing a product to an audience that is purchasing the product, but your audience might not be the ones that use the product. For example, Diapers.
