In cooperation with the SAT marketing agency, we were able to create an elaborate promotional spot that was the centerpiece of a marketing campaign for the renowned Swiss brand On running, targeting the Polish market. Our goal was not only to promote the products, but also to build brand awareness by telling the inspiring story of an acclaimed ultramarathoner from Przemyśl. The result was an 8-minute documentary that not only showcased On running's unique products, but also drew the viewer into a fascinating journey through the life story of an ultramarathoner. Through careful scripted compositions, we managed to enrich the narrative with emotion and authenticity, which made the film not only inform, but also move the audience. During the production, we focused on showing not only the products themselves, but also how they affect the daily life and achievements of the ultramarathoner. The visual effects used, precise shots and dynamic editing allowed us to integrate the story with the presentation of the products in a coherent way. The marketing campaign, in which this film was a key element, received a positive response in the Polish market, building not only awareness of the On running brand, but also inspiring the running community to identify with the values of the promoted brand. The success achieved confirmed the effectiveness of our approach to film production as part of comprehensive marketing strategies.
