## 🌟 Overview

**Code2Video** is an **agentic, code-centric framework** that generates high-quality **educational videos** from knowledge points.  
Unlike pixel-based text-to-video models, our approach leverages executable **Manim code** to ensure **clarity, coherence, and reproducibility**.

**Key Features**:
- 🎬 **Code-Centric Paradigm** — executable code as the unified medium for both temporal sequencing and spatial organization of educational videos.
- 🤖 **Modular Tri-Agent Design** — Planner (storyboard expansion), Coder (debuggable code synthesis), and Critic (layout refinement with anchors) work together for structured generation.
- 📚 **MMMC Benchmark** — the first benchmark for code-driven video generation, covering 117 curated learning topics inspired by 3Blue1Brown, spanning diverse areas.
- 🧪 **Multi-Dimensional Evaluation** — systematic assessment on efficiency, aesthetics, and end-to-end knowledge transfer.

---

## 🚀 Try Code2Video

### 1. Requirements

```bash
cd src/
pip install -r requirements.txt
````

Here is the [official installation guide](https://docs.manim.community/en/stable/installation.html) for [Manim Community v0.19.0](https://www.manim.community/), to help everyone correctly set up the environment.

### 2. Configure LLM API Keys

Fill in your **API credentials** in `api_config.json`.

* **LLM API**: 
  * Required for Planner & Coder.
  * Best Manim code quality achieved with **Claude-4-Opus**.
* **VLM API**:
  * Required for Planner Critic.
  * For layout and aesthetics optimization, provide **Gemini API key**.
  * Best quality achieved with **gemini-2.5-pro-preview-05-06**.

* **Visual Assets API**:

* To enrich videos with icons, set `ICONFINDER_API_KEY` from [IconFinder](https://www.iconfinder.com/account/applications).

### 3. Run Agents

We provide two shell scripts for different generation modes:

#### (a) Any Query

Script: `run_agent_single.sh`

Generates a video from a single **knowledge point** specified in the script.

```bash
sh run_agent_single.sh --knowledge_point "Linear transformations and matrices"
```

**Important parameters inside `run_agent_single.sh`:**

* `API`: specify which LLM to use.
* `FOLDER_PREFIX`: output folder prefix (e.g., `TEST-single`).
* `KNOWLEDGE_POINT`: target concept, e.g. `"Linear transformations and matrices"`.

---

#### (b) Full Benchmark Mode

Script: `run_agent.sh`

Runs all (or a subset of) learning topics defined in `long_video_topics_list.json`.

```bash
sh run_agent.sh
```

**Important parameters inside `run_agent.sh`:**

* `API`: specify which LLM to use.
* `FOLDER_PREFIX`: name prefix for saving output folders (e.g., `TEST-LIST`).
* `MAX_CONCEPTS`: number of concepts to include (`-1` means all).
* `PARALLEL_GROUP_NUM`: number of groups to run in parallel.

### 4. Project Organization

A suggested directory structure:

```
src/
│── agent.py
│── run_agent.sh
│── run_agent_single.sh
│── api_config.json
│── ...
│
├── assets/
│   ├── icons/          #  downloaded visual assets cache via IconFinder API
│   └── reference/      # reference images
│
├── json_files/         # JSON-based topic lists & metadata
├── prompts/            # prompt templates for LLM calls
├── CASES/              # generated cases, organized by FOLDER_PREFIX
│   └── TEST-LIST/      # example multi-topic generation results
│   └── TEST-single/    # example single-topic generation results
```

## 📊 Evaluation -- MMMC

We evaluate along **three complementary dimensions**:

1. **Knowledge Transfer (TeachQuiz)**

```bash
   python3 eval_TQ.py
   ```

2. **Aesthetic & Structural Quality (AES)**

```bash
   python3 eval_AES.py
   ```

3. **Efficiency Metrics (During Video Creating)**

* Token usage
   * Execution time

👉 More data and evaluation scripts are available at:
[HuggingFace: MMMC Benchmark](https://huggingface.co/datasets/YanzheChen/MMMC)

## 🙏 Acknowledgements

* Video data is sourced from the **[3Blue1Brown official lessons](https://www.3blue1brown.com/#lessons)** and **[Grant Sanderson](https://x.com/3blue1brown)**.
  These videos represent the **upper bound of clarity and aesthetics** in educational video design and inform our evaluation metrics.
* We thank all the **Show Lab @ NUS** members for support!
* This project builds upon open-source contributions from **Manim Community** and the broader AI research ecosystem.
* High-quality visual assets (icons) are provided by **[IconFinder](https://www.iconfinder.com/)** and  **[Icons8](https://icons8.com/icons)**, which were used to enrich the educational videos.
