🔥 Update

Any contributions are welcome!

• [2025.11.25] Our Code2Video has reached 1000 stars!
• [2025.11.06] We optimized requirements.txt, which resulted in an 80-90% reduction in installation time. Thanks to daxiongshu!
• [2025.10.11] Due to issues on ICONFINDER, we’ve updated Code2Video auto-collected icons at MMMC as a temporary alternative.
• [2025.10.6] We have updated the ground truth human-made videos and metadata for the MMMC dataset.
• [2025.10.3] Thanks @_akhaliq for sharing our work on Twitter!
• [2025.10.2] We release the arXiv, code and dataset .
• [2025.9.22] Code2Video has been accepted to the Deep Learning for Code (DL4C) Workshop at NeurIPS 2025.

🌟 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

cd src/
pip install -r requirements.txt

Here is the official installation guide for Manim Community v0.19.0, 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.

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.

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.

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)

   python3 eval_TQ.py

2. Aesthetic & Structural Quality (AES)

   python3 eval_AES.py

3. Efficiency Metrics (During Video Creating)

   • Token usage
   • Execution time

🙏 Acknowledgements

• Video data is sourced from the 3Blue1Brown official lessons and Grant Sanderson. 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 and Icons8, which were used to enrich the educational videos.
