The video demonstrates how to use a Python script to replace the audio in video files with AI-generated voices from ElevenLabs, allowing users to select voices and process audio in manageable chunks. The presenter explains the script’s functionality, including adjusting audio volume and ensuring the final output matches the video’s duration, while also promoting additional educational content and resources available on their Patreon page.
In this video, the presenter demonstrates how to use a Python script to replace the audio in video files with AI-generated voices from ElevenLabs. The process begins by running a script that lists all available MP4 files, allowing the user to select a specific video for audio replacement. The script is designed to handle audio in chunks, with a default chunk time set to 15 seconds for testing purposes. The presenter showcases the functionality by selecting a voice from ElevenLabs and processing a sample audio clip.
The script is capable of processing longer videos by adjusting the chunk time to a maximum of 300 seconds, which is necessary due to the limitations of the ElevenLabs voice API. The presenter explains that users can test different voices by setting shorter chunk times, which helps in evaluating various voice options without incurring high costs. The video also highlights the ease of use of the script, which automatically increases the audio volume by 25% and saves the processed video with the new audio.
To select voices from ElevenLabs, the presenter guides viewers through the process of navigating the ElevenLabs voice library. Users can find and add voices to their collection, retrieve the voice ID, and input it into the script. The video emphasizes the importance of having an ElevenLabs API key and the necessary Python libraries installed, such as MoviePy and Requests, to ensure the script functions correctly.
The presenter provides a detailed overview of the code, explaining how it converts video files to MP3, splits audio into manageable chunks, and processes each chunk with the selected voice. The script also includes functions to replace the original audio in the video with the newly generated audio, ensuring that the final output matches the video’s duration. The presenter encourages viewers to modify the code as needed and offers access to the code files through their Patreon page.
In addition to the main tutorial, the presenter promotes their website and additional educational content, including a masterclass on building applications with various technologies. They highlight the value of their Patreon offerings, which include personal coaching and consulting services. The video concludes with an invitation for viewers to explore more of their content and stay tuned for future tutorials.
