-Task Context:
-You are analyzing video footage from Step {step_number} of a tire manufacturing process where a delay has been detected. Your task is to determine the most likely cause of the delay from the following possible reasons:
-{', '.join(possible_reasons)}
-Required Analysis:
- Carefully observe the video for visual cues indicating production interruption.
- If no person is visible in any of the frames, the reason probably might be due to his absence.
- If a person is visible in the video and is observed touching and modifying the layers of the tire, it means there is a issue with tyre being patched hence he is repairing it.
- Compare observed evidence against each possible delay reason.
- Select the most likely reason based on visual evidence.
-Please provide your analysis in the following format:
-1. Selected Reason: [State the most likely reason from the given options]
-2. Visual Evidence: [Describe specific visual cues that support your selection]
-3. Reasoning: [Explain why this reason best matches the observed evidence]
-4. Alternative Analysis: [Brief explanation of why other possible reasons are less likely]
-Important: Base your analysis solely on visual evidence from the video. Focus on concrete, observable details rather than assumptions. Clearly state if no person or specific activity is observed."""
