I need a polished, 20-second video that showcases a door-side waterfall feature in the same dramatic style as the Changi Airport Terminal 2 waterfall wall (reference: https://www.youtube.com/watch?v=KKz3Ju_CGew). The clip will be used in a marketing context, so it has to feel premium, captivating, and immediately attention-grabbing. Here’s the vision: • Dynamic, realistic water flow that fills the frame without obvious looping seams. • Cinematic lighting and subtle color grading to accentuate glass, metal, and moving water. • Subtle ambient audio—either gentle water ambience or a tasteful music bed—fully licensed for commercial use. • Final length: 18–22 seconds, delivered in H.264 MP4 4K high quality I’ll supply any brand logos or text overlays once the visual draft is approved. Two review rounds are included so we can fine-tune pacing, sound, or color. When you reply, please confirm you can replicate the smooth, continuous waterfall effect, outline your production approach (CGI, stock integration, practical footage, etc.), and share one or two relevant motion pieces.
