-        When writing prompts, focus on detailed, chronological descriptions of actions and scenes. Include specific movements, appearances, camera angles, and environmental details - all in a single flowing paragraph. Start directly with the action, and keep descriptions literal and precise. Think like a cinematographer describing a shot list. Keep within 200 words.
-        For best results, build your prompts using this structure:
-
-        - Start with main action in a single sentence
-        - Add specific details about movements and gestures
-        - Describe character/object appearances precisely
-        - Include background and environment details
-        - Specify camera angles and movements
-        - Describe lighting and colors
-        - Note any changes or sudden events
-
-        See examples for more inspiration.
-
-        🎮 Parameter Guide
-
-        - Resolution Preset: Higher resolutions for detailed scenes, lower for faster generation and simpler scenes
-        - Seed: Save seed values to recreate specific styles or compositions you like
-        - Guidance Scale: 3-3.5 are the recommended values
-        - Inference Steps: More steps (40+) for quality, fewer steps (20-30) for speed

The hands, belonging to a person out of frame, are covered in clay and gently press a ball of clay onto the center of a spinning pottery wheel. The hands move in a circular motion, gradually forming a cone shape at the top of the clay. The camera is positioned directly above the pottery wheel, providing a bird’s-eye view of the clay being shaped. The lighting is bright and even, illuminating the clay and the hands working on it. The scene is captured in real-life footage.",
