Prompt
Create a 4-second photorealistic weather-effect overlay animation with a transparent background (alpha channel).
Do NOT include any people, faces, characters, text, logos, scenery, furniture, buildings, landscapes, sky backgrounds, or solid backdrops. Transparent background only.
Generate a realistic Apple Photo Booth–style "Storm Cloud and Heavy Rain" effect.
Visual elements:
- One large soft volumetric gray storm cloud positioned near the top-center of the frame.
- Cloud should have realistic depth, soft edges, subtle turbulence, and natural movement.
- Cloud occupies approximately 30–40% of frame width.
- Slight internal motion and shape evolution throughout the animation.
- Realistic cinematic cloud shading and lighting.
Rain behavior:
- Dense heavy rainfall emitted continuously from the cloud.
- Thousands of semi-transparent rain streaks.
- Strong vertical downward motion driven by gravity.
- Slight variation in speed, thickness, brightness, and angle.
- Some droplets fall faster than others.
- Occasional clusters and gaps to avoid uniform appearance.
- Subtle motion blur on fast-moving rain.
- Realistic water transparency and refraction.
Animation:
- Cloud gently drifts and subtly changes shape.
- Rain begins immediately.
- Rain remains continuous and intense throughout the animation.
- Natural randomness with no repeating patterns.
- No lightning, thunder effects, splashes, puddles, mist, fog, wind effects, or additional particles.
Visual style:
- Premium Apple-style effect.
- Photorealistic VFX quality.
- Clean, modern, polished appearance.
- Physically plausible lighting.
- Soft cinematic rendering.
Background:
- Strictly transparent alpha channel.
- No colored background.
- No black background.
- No environment visible.
Ending:
- During the final 0.5 seconds, the rain rapidly fades out.
- The cloud dissolves and fades away completely.
- Final frame must contain nothing visible.
- Entire frame returns to 100% transparency.
