How I created AI Avatar with Open-Source Tools | Ultimate Guide
Science & Technology
Introduction
Creating a realistic AI avatar is a challenging yet rewarding task, especially considering the obstacles posed by high costs and unsatisfactory results from many AI avatar services. However, with my recent journey into developing an AI avatar using primarily open-source tools, I've discovered an economical and efficient workflow that yields great results. Below is a detailed account of my process, from generating images to creating lifelike animations.
Step 1: Generating the Avatar Image
To begin, you'll need an image of your avatar. Any image generator can work, but I recommend using tools like Focus UI. By providing a detailed prompt, you'd be able to create a polished image. For instance, I used the following prompt to generate a clear profile picture and managed to extend the image further with Focus UI to optimize it for animation.
Step 2: Animating the Avatar
While many AI tools animate the face effectively, they fail to animate the full body adequately, resulting in unnatural movements. To solve this, I used Live Portrait, which is a lightweight tool that animates facial features. However, remember that it requires a GPU to operate smoothly.
To address body animation, I turned to Luma AI and Clink AI to generate videos from images. Although these tools are mostly free, they often come with long wait times for results. It’s crucial to be patient and experiment with different prompts to achieve the desired outcome.
Upon generating the initial animation, I faced a couple of challenges, including watermarks and the limited length of videos. Fortunately, these issues can be resolved using basic video editing software, such as DaVinci Resolve, where you can remove watermarks and extend video durations.
Step 3: Creating the Driving Video
Next, you'll need a driving video to animate your avatar convincingly. You can record yourself narrating a script or find online services that can animate based on audio input. While some might not offer great results, options like Set Talk are particularly efficient and free.
After setting up your driving video, the ideal approach is to choose a neutral expression on the first frame for optimal animation quality. Then, using the Live Portrait software, you can select your avatar's image as the source and synchronize it with your driving video to create the animated output.
Step 4: Fine-tuning and Editing
Once you have your animated video, you’ll likely want to change the audio to fit your avatar’s character. For this, Eleven Labs offers voice modulation services, allowing you to transform the original voice while keeping the speech timing constant.
To alter the audio, I extracted it from the animated video, set it to a compatible format, and then let Eleven Labs generate the new audio. The final step involves merging the new audio file back into the animated video using video editing software.
Final Thoughts
Overall, even though this process may seem daunting with multiple steps, it becomes much easier with practice. This guide provides a foundation to create your AI avatar using various open-source tools, maximizing affordability and accessibility without compromising quality.
