As an experienced and talented Video Editor, Animator, and Audio Engineer with over 6+ years of experience under my belt, I am confident in my abilities to deliver exactly what you need for this charity event.
When creating a promotional video, I always have the end-viewer in mind. My understanding of target audience engagement means that I know how to communicate messages clearly and succinctly, using visuals and sounds that will not only grab attention but also create excitement. This is crucial for an event like yours where you not only want to inform but also encourage participation.
Furthermore, although it wasn't listed as a necessary skill - I have actually created content for charity events before. This familiarity with the specific needs and tone needed for these type of events will aid me enormously in effectively conveying the purpose and mission of your event. With me on board, you can be assured of a video that not only highlights the two causes but also provides a short intro to the organization behind the event, making it even more impactful.
