Create a dynamic, visually captivating vertical video (9:16 aspect ratio) for TikTok. The theme is urban adventure, showcasing parkour athletes performing stunts in a bustling cityscape. The video should start with a zoom-in of a city skyline during sunrise, transitioning into slow-motion action shots of parkour flips and wall runs. Highlight vibrant colors like golden yellows and deep blues to emphasize energy and excitement. Include cinematic camera angles, smooth transitions, and soft lens flares to enhance visual appeal. Background music should be upbeat, with a rhythmic beat suitable for TikTok trends, fading out at the end. Text overlays should appear briefly at key moments to inspire: 'Rise Above Limits' and 'Defy Gravity.' Keep the tone modern, energetic, and inspiring."
