Always treat the user’s request as the guiding vision, and reinterpret the image so that the final video concept fulfills that request. Your output must be only the plain text report as described below. Do not include any conversational filler or explanatory text.\n\nUSER REQUEST\n{{ $json[\"Image Prompt\"] }}\n\nIMAGE ANALYSIS\n\nDescription\nWrite a comprehensive, single-paragraph description of the image as it visually appears. Then explicitly describe how this image can be creatively reimagined or transformed to align with the user’s request.\n\nStyle Analysis\n\nCore Subject: Identify the main focus of the image and explain how it connects to the user’s request.\n\nSetting: Describe the environment/background and how it could be reinterpreted in the requested concept.\n\nMedium: Specify the artistic medium (e.g., product photography, 3D render) and suggest how the medium might shift in the video.\n\nLighting: Describe the current light and suggest adjustments to match the requested mood.\n\nMood: Define both the existing atmosphere of the image and the intended emotional tone per the user’s request.\n\nComposition: Describe the current framing/camera angle and how it might evolve in the video.\n\nColor Palette: List the dominant colors, then suggest enhancements or transformations to match the user’s request.\n\nText Overlay\nList and describe each distinct piece of text found in the image. If there is no text, simply write \"None.\"\n\nFor each text element, provide:\n- Text\n- Font\n- Effect\n- Color\n- Placement\n\nCREATIVE VIDEO BRIEF\n\nTranslate the user request and image analysis into a structured video brief suitable for Veo 3 generation:\n\nVideo Style: Describe the final style/genre of the requested video.\n\nTarget Emotion: Define the main emotional impact the video should deliver.\n\nMotion Guidance: Suggest dynamic camera motions, transitions, or visual effects that bring the user’s request to life.\n\nAudio/Music Direction: Suggest music/sound design that fits both the brand identity in the image and the requested theme.\n\nSuggested Script Elements: Provide a draft outline of possible voiceover or on-screen text. Ensure this ties the image (e.g., Pepsi product) with the user’s creative request (e.g., exploding into a disco party).\n",
