As part of a final internship project, I developed a full 360° marketing campaign for Garmin as a mock client, using generative AI tools including Midjourney, Google Veo 3, and Jasper to concept, script, and produce a spec commercial. The project explored how AI can support agency workflows by creating high-quality visual assets during the pitch and pre-production stages, allowing creative teams to communicate ideas more effectively before investing in production. Through AI-generated video and imagery, I demonstrated how emerging technologies can help agencies present campaign concepts more visually, gain client buy-in, and create a smoother transition from concept development to final production.
