Create a 14-second solar eclipse entirely in After Effects. Start with a bright sun above a desert mesa skyline, then slide the moon across into totality so the sky darkens, stars come out, and a glowing corona with red prominences appears before daylight returns. Give the horizon a warm glow and make the whole thing feel cinematic. Build it procedurally with no footage, and add controls for eclipse phase, corona color, prominence color, and horizon glow so I can release it as a template.
