TCA-Bench Evaluation Protocol

The evaluator scores candidate audiovisual captions in four stages:

• 1v: Stage-1 visual caption quality against gt/captions.json.
• 1a: Stage-1 audio caption quality against gt/captions.json.
• 2: Stage-2 audio-visual binding accuracy against gt/stage-2.json.
• 3: Stage-3 temporal relation F1 against gt/stage-3.json.

Prompt files are located in prompts/. caption_prompt.txt is the recommended prompt for generating candidate captions before evaluation.
