+###  🤗 About This Repo
+
+This repository contains annotation data for "Video-MME-v2: Towards the Next Stage in Benchmarks
+for Comprehensive Video Understanding". It mainly consists of three parts: `videos/`, `test.parquet`, and `subtitle.zip`.
+
+- `videos/` contains **800 1080p MP4 files**, organized sequentially into 40 zip archives. For example, `001.mp4` to `020.mp4` are stored in `001.zip`.
+
+- `test.parquet` contains **3200 QA instances**, with each video paired with **4 questions**. Each instance includes the **question**, **options**, **answer**, and auxiliary metadata such as the **video id** and **QA category**.
+
+- `subtitle.zip` contains **800 JSONL files**, named `{001..800}.jsonl`, each corresponding to a video id. Each file contains word-level entries with timestamps.

+### 👀 Dataset Intro
+
+In 2024, our [**Video-MME**](https://video-mme.github.io/) benchmark became a standard evaluation set for frontier models like Gemini and GPT. However, as model capabilities rapidly evolve, scores on existing benchmarks are saturating, yet a clear gap remains between **leaderboard performance and actual user experience**. This indicates that current evaluation paradigms fail to capture true video understanding abilities. To address this, we spent a year redesigning the evaluation system from first principles and now introduce **Video-MME v2**—a progressive and robust benchmark designed to drive the next generation of video understanding models.
+
+- **Dataset Size**
+
+  The dataset consists of 800 videos and 3,200 QA pairs, with each video associated with four MCQ-based questions.
+
+- **Multi-level Evaluation Hierarchy**
+
+  - 🔍 **Level 1:** Retrieval & Aggregation
+  - ⏱️ **Level 2:** Level 1 + Temporal Understanding
+  - 🧠 **Level 3:** Level 2 + Complex Reasoning.
+
+- **Group-based Evaluation Strategy**
+
+  - **Capability consistency groups** examine the breadth of a specific fundamental perception skill.
+  - **Reasoning coherence groups** assess the depth of a model’s reasoning ability.
+
+- **Video Sources**
+
+  All videos are collected from YouTube. Over 80% were published in 2025 or later, with nearly 40% published after October 2025.
+
+- **Video Categories**
+
+  The dataset includes four top-level domains, further divided into 31 fine-grained subcategories.
+
+- **Metrics**
+
+  A non-linear scoring mechanism is applied to all question groups, and a first error truncation mechanism is used for reasoning coherence groups.

+### 🙌 Example
+
+<video controls width="100%" src="assets/demo.mp4"></video>
+
+**Q1:** Does the ball exist underneath any of the shells?
+A. No.
+B. Yes.
+C. Cannot be determined.
+
+**Q2:** Underneath which shell is the ball located at the end?
+A. There is no ball under any shell.
+B. The third shell.
+C. The sixth shell.
+D. The second shell.
+E. The seventh shell.
+F. The fifth shell.
+G. The fourth shell.
+H. The first shell.
+
+**Q3:** The host performed a total of two shell swaps (defining a single swap as an instance where all shells return to an approximately straight line). Underneath which shell was the ball located after the first swap?
+A. There is no ball under any shell.
+B. The seventh shell.
+C. The fourth shell.
+D. The fifth shell.
+E. The sixth shell.
+F. The second shell.
+G. The third shell.
+H. The first shell.
+
+**Q4:** The host performed a total of two shell swaps (defining a single swap as an instance where all shells return to an approximately straight line). Underneath which shell was the ball located initially?
+A. The seventh shell.
+B. The fourth shell.
+C. The fifth shell.
+D. The third shell.
+E. The second shell.
+F. There is no ball under any shell.
+G. The first shell.
+H. The sixth shell.
