Static camera. Create a smooth atmospheric transition between the two keyframes. Animate only the clouds. The clouds move slowly and naturally with realistic atmospheric flow. They gently drift, expand, contract and subtly change shape. Soft moving cloud shadows and reflections glide naturally across the terminal glass and metal surfaces. The entire motion must remain smooth and continuous from beginning to end. No sudden changes. No abrupt morphing. No popping. No flickering. No frame jumps. No visible transition point. No sudden acceleration or deceleration. Everything except the clouds remains completely static. No camera movement. No zoom. No pan. No tilt. No moving vehicles. No people. No aircraft. No birds. No tree movement. Ultra-photorealistic cinematic architectural footage with physically accurate lighting and natural atmospheric motion.
