.venv\Scripts\activate
pip install -r requirements.txt
For Linux or Mac
python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
Also install sadtalker(https://github.com/OpenTalker/SadTalker#%EF%B8%8F-1-installation), the sadtalker directory must be inside backend. Run the sadtalker webui once so that the venv environment is created.
Add your Cohere API key to backend/apikeys.json
🔌 How to use
Open up a terminal and go to frontend/topic2explanation
npm run dev
Open up another terminal and go to backend
uvicorn main:app
🎨 Customizability
To change the character and voice, you need to put your desired character in characters directory. It must be in 640x720 resolution and for the voice you can choose a voice from the voice list which can be seen using this command.
edge-tts --list-voices
Once you find a voice you like add it in the create_audio_image function
character_dict = {'Benjamin': "en-GB-RyanNeural",
'Sophia': 'en-IE-EmilyNeural'}
📝 How it works
✨ It all starts with the creation of a script using the create_script function. 📜 This function takes various parameters such as topic, level of explanation, target audience age, creativity, and humor. 🎭 With these parameters in mind, the script is carefully crafted to explain the chosen topic. To accomplish this, we leverage the power of the Cohere API and Langchain. 🤝
🎙️ Once the script is ready, we move on to the create_audio_image function. This function splits the script into smaller sentences, which are then used to generate audio dialogues using Microsoft's Edge Text-to-Speech (TTS) service. 🗣️ In parallel, we generate a search query for each sentence using Cohere and Langchain once again. These search queries help us retrieve relevant images from Google, which will be used as slides in the presentation. 🖼️
🎥 With the audio files and character images in place, we proceed to create the videos using the Sadtalker library. 🎬 First, we generate videos for the character animations, and then we transform the still images from Google into slide videos. 🎞️ These slide videos will be seamlessly integrated into the final video presentation. To add an element of randomness, we assign a random number to each video and slide pair. Based on this number, we position the slides and talking character either to the left or right, or even use the image as the background. The talking character may appear in the bottom left or right corner of the screen. 🎯
📼 Finally, we save the completed video, combining the slide videos and character animation videos. The resulting video is now ready to be shared! 🎉 To bring it all together, we rely on FastAPI for the backend, and for the frontend, we utilize Next.js and Tailwind CSS. 🚀
