A product film gives the viewer an impression of what kind of products or services you are offering. It is a promotional or explanatory film that either 'sells' or explains a product or service by showing the characteristics of them. It is done in the best way moving images allow. It is a very free format, in the sense that it leaves room for many different styles and techniques. Product films are especially well suited for external communication purposes. They are often used for online marketing and placed on websites and social media and for eCommerce.
