+            Duration: {duration} seconds
+            Description: {description}
+            IMPORTANT INSTRUCTIONS:
+            1. Create detailed scene descriptions that include:
+               - Physical appearance of people (age, gender, clothing, hair, etc.)
+               - Exact actions being performed
+               - Dialogue or speech (include actual lines if audible, or infer probable spoken lines based on actions and setting; format them as "Character: line...")
+               - Setting and environment details
+               - Props, objects, or products being shown
+               - Visual effects, text overlays, or graphics
+               - Mood, tone, and atmosphere
+               - Camera movements or angles (if apparent)
+            2. Dialogue Emphasis:
+               - Include short dialogue lines in **every scene** wherever plausible.
+               - Write lines like: Character: "Actual or inferred line..."
+               - If dialogue is not available, intelligently infer probable phrases (e.g., "Welcome!", "Try this now!", "It feels amazing!").
+               - Do NOT skip dialogue unless it's clearly impossible.
+            3. Timestamp Guidelines:
+               - For videos under 1 minute: 2-3 second segments
+               - For videos 1-5 minutes: 3-5 second segments
+               - For videos 5-15 minutes: 5-10 second segments
+               - For videos over 15 minutes: 10-15 second segments
+               - Maximum 20 scenes total for longer videos
+            4. Format each scene EXACTLY like this:
+               **[MM:SS-MM:SS]**: Detailed description including who is visible, what they're wearing, what they're doing, what they're saying (if applicable), setting details, objects shown, and any visual elements.
+            5. Write descriptions as if you're watching the video in real-time, noting everything visible and audible.
+            Based on the title and description, intelligently infer what would likely happen in each time segment. Consider the video type and create contextually appropriate, detailed descriptions.
