Make a 20-second 16:9 motion graphics video that tells a little story with sound. For the first 12 seconds there is no sound at all: on a warm paper background, the words "make it catchy." type themselves out, then the letters fall apart and build a colorful music machine piece by piece: ramps, spinning gears, a row of blocks like piano keys and a big drum. It ends with a ball waiting at the top. At 12 seconds the ball drops and the machine comes alive. Every block it hits plays a note, the drum kicks, the gears tick in rhythm, and it all becomes a catchy 4-second beat. Then everything snaps into the words "ONE PROMPT" on a final hit, followed by silence. Use bold geometric shapes in ink black, cobalt blue and sunflower yellow, and make every sound match a movement you can see. Go all out and render the final MP4.
