This project demonstrates how to create a tutorial video using Manim and gTTS. The tutorial covers setting up an Apache Airflow DAG for mapping ontology data from an API.

The project uses the following dependencies:

• Python 3.12
• Manim 0.18.1
• gTTS 2.5.4
• pydub 0.25.1

1. Clone the repository:

   git clone <repository-url>
   cd voiceover

2. Install dependencies using Poetry:

   poetry install

1. Generate Voiceover Audio:

   poetry run python src/generate_voiceover_audio.py

2. Render Slides Using Manim:

   poetry run manim -pql src/tutorial_script.py AirflowTutorial

3. Combine Audio Files:

   poetry run python src/combine.py

4. Merge Audio with Video Using FFmpeg:

   ffmpeg -i media/videos/tutorial_script/480p15/partial_movie_files/AirflowTutorial/partial_movie_file_list.txt -i voiceover_audio.mp3 -c:v copy -c:a aac final_video.mp4
