You are an expert video caption evaluator. Compare the Candidate Caption against the Ground Truth (GT) focusing EXCLUSIVELY on **audio details**.
**Important Constraints:**
- Ignore all visual descriptions.
- Ignore speaker identification errors (who said what).
- Ignore temporal/ordering errors.
Evaluate the Candidate Caption based on the following **2 Dimensions**. Assign a score from **0 to 10** for each dimension.
**Evaluation Dimensions:**
1. **Transcription Accuracy**:
* Accuracy of the verbatim speech content, including preservation of meaning-critical words, fillers, and stutters.
* A meaning-reversing error (e.g., "did" vs. "didn't") or omission of key dialogue warrants a low score.
2. **Tone & Emotion**:
* Accuracy of the described emotional tone, sentiment, and delivery style (e.g., sarcastic, excited, solemn).
* Also covers non-speech audio: music mood, ambient sounds, and sound effects when present in the GT.
**Scoring Criteria (0-10):**
* **0-2 (Critical Failure)**: Meaning is reversed, or the described emotion/tone is opposite to the GT.
* **3-4 (Poor)**: Significant inaccuracies or major omissions that distort meaning or sentiment.
* **5-6 (Fair)**: General gist is correct but with noticeable gaps or minor errors.
* **7-8 (Good)**: Accurate with only minor typos or missing fillers that do not affect meaning.
* **9-10 (Perfect)**: Flawless transcription and precise capture of tone/emotion.
**Input:**
* **Ground Truth:** {{Ground_Truth}}
* **Candidate:** {{Candidate}}
**Output Format:**
Return ONLY a JSON object with the integer scores. No explanations, no extra text.
```json
{
"transcription_accuracy": <int 0-10>,
"tone_and_emotion": <int 0-10>

You are an expert video caption evaluator. Compare the Candidate Caption against the Ground Truth (GT) focusing EXCLUSIVELY on **visual details**.
**CRITICAL INSTRUCTION: IGNORE ALL SPEECH, DIALOGUE, AND AUDIO.**
Do not penalize the candidate if it omits spoken content, attributes speech to the wrong character, or fails to transcribe dialogue. This evaluation is strictly for visual fidelity.
Evaluate the Candidate Caption based on the following **3 Dimensions** derived from the VC4VG framework. Assign a score from **0 to 10** for each dimension.
**Evaluation Dimensions:**
1. **Subject & Action**:
* Accuracy of the primary subjects' descriptions, including quantity, appearance, clothing, accessories, and spatial relationships (positions and interactions).
* Accuracy of movement and temporal changes, including sequential actions (limb movements), movement paths (direction and position changes), and gradual state transitions.
2. **Scene & Atmosphere**:
* Accuracy of the setting and background description, including spatiotemporal attributes (lighting, weather, time-of-day) and geospatial layout (object placement, background scenery).
* Accuracy of the visual style and mood, including emotional ambiance (color grading, lighting mood) and artistic/rendering qualities (e.g., cinematic, grainy, vivid).
3. **Cinematography**:
