Introduction

Creating video content is time-consuming, expensive, and often requires extensive technical expertise. Traditional video production involves filming, editing, and post-production work that can take hours—even days—to complete. But what if you could bypass these steps entirely and generate high-quality videos with just a few clicks? That’s the promise of my AI agent: a no-code solution that turns YouTube videos into personalized AI avatar videos, enabling you to repurpose content, save time, and even monetize your efforts in new and exciting ways.

In this detailed guide, I share my journey of building an AI agent that takes a YouTube video as input, extracts its transcript, repurposes it, and finally generates a new video featuring an AI-generated avatar with my own voice. This innovative approach opens up new avenues for content creators to extend the lifespan of their videos and create engaging, personalized content without the usual hassle of video production.

The Vision Behind the AI Agent

The idea came from a common challenge: many of us have a backlog of YouTube videos that still hold value but are rarely revisited by audiences. Instead of letting these videos go to waste, why not transform them into something fresh—like AI avatar videos that not only repackage the content but also add a personal touch?

I envisioned a tool that could:

  • Automate the process of video repurposing.
  • Customize the output by incorporating my own voice and avatar.
  • Save Time and Money by eliminating the need for traditional filming and editing.

By leveraging the latest AI technologies, I set out to build an agent that would not only meet these needs but also provide a seamless, no-code workflow for creators of all skill levels.

Overview of the No-Code Workflow

At a high level, the AI agent workflow consists of two major parts:

  1. Transcript Extraction and Repurposing:
    Using a combination of the DeepSeek V3 and Search API, the agent extracts the transcript from a YouTube video, refines it, and formats it for further processing.
  2. AI Avatar Video Generation:
    The refined transcript is then fed into an AI video generator (Heen) that produces a new video featuring an AI-generated avatar. The avatar uses my voice and a pre-set visual style, effectively repurposing the original video into a unique, personalized piece of content.

The entire process is automated, from extracting the transcript to uploading the final video, all without writing any code. This approach is ideal for content creators who want to focus on creativity rather than technical details.

Essential Tools and APIs

To build this AI agent, I integrated several cutting-edge tools and APIs. Here’s a breakdown of the key components:

Heen: AI Avatar Video Generator

Heen is an innovative tool that allows you to create AI-generated videos featuring a custom avatar. It uses advanced machine learning algorithms to analyze text prompts and generate videos that match the specified style and tone. With Heen, you can easily produce videos that reflect your brand’s personality and unique style without ever stepping in front of a camera.

DeepSeek V3

DeepSeek V3 is an open-source model designed to extract and repurpose transcripts from video content. It’s powerful enough to outperform many closed-source alternatives, providing accurate transcripts that form the basis for your new video content. This tool is critical in transforming lengthy YouTube videos into concise, actionable scripts suitable for AI avatar generation.

Search API for Transcript Extraction

The Search API is used to retrieve transcripts directly from YouTube videos. By inputting the video ID, the API fetches the auto-generated or manually provided transcript, which can then be processed and repurposed. This step is essential for ensuring that the content is accurately captured and ready for the next stage of the workflow.

Step-by-Step Guide to Building the AI Agent

Let’s dive deeper into each step of the workflow, outlining how the entire process comes together.

Step 1: Choosing the Source Video

The process begins with selecting a YouTube video that you wish to repurpose. In my case, I chose a video about “DeepSeek V3” that was approximately 4 minutes long. The idea is to convert this longer video into a short, engaging AI avatar video that captures the essence of the original content.

  • Key Considerations:
    • Relevance: Choose a video that has valuable information or a compelling story.
    • Length: Longer videos can be condensed into short clips that are easier to consume.
    • Quality: Ensure that the original video has clear audio and visuals to facilitate accurate transcript extraction.

Step 2: Extracting the Transcript

Once you’ve selected the video, the next step is to extract the transcript. This is done using the Search API in combination with DeepSeek V3.

  • Process:
    1. Input Video ID: Use the YouTube video ID to fetch the transcript.
    2. API Integration: The Search API retrieves the transcript in JSON format.
    3. Validation: Review the transcript to ensure it captures all essential parts of the video.

The extracted transcript forms the foundation for the repurposed content. It’s important to verify its accuracy because any errors here will propagate through the rest of the process.

Step 3: Repurposing the Transcript

With the transcript in hand, the next step is to transform it into a script suitable for a short AI avatar video.

  • Editing the Content:
    • Conciseness: Condense the transcript to highlight the key points.
    • Clarity: Adjust the language to be direct and engaging.
    • Personalization: Tailor the script to include your own style and voice, ensuring that the final video feels authentic.

This step may involve minor tweaks, such as rephrasing sentences or removing unnecessary filler content. The goal is to produce a concise script that conveys the original message effectively in a shorter format.

Step 4: Generating the AI Avatar Video

Now that the script is ready, it’s time to generate the AI avatar video using Heen.

  • Setting Up Heen:
    1. Sign Up: Create an account on Heen and choose the free plan if available.
    2. Create Your Avatar: Record a 2–5 minute video of yourself following guidelines (use a high-resolution camera, ensure proper lighting, pause between sentences, etc.) to create a personalized avatar.
    3. Upload the Script: Input the refined script into Heen. The AI uses this script to generate the video, aligning the avatar’s lip movements and expressions with your voice.
  • Workflow Integration:
    The Heen API is then used to automate the generation process. By sending the script and avatar parameters through the API, the system produces a short video—around 21 seconds in my demo—that effectively repurposes the original content.

Step 5: Automating the Workflow

The final stage involves automating the entire process, ensuring that each step flows seamlessly into the next without manual intervention.

  • API Credentials:
    Set up and integrate the necessary API keys for Heen, DeepSeek, and the Search API. These credentials authenticate your requests and allow for smooth data transfer between tools.
  • Workflow Execution:
    1. Transcript Extraction: The system automatically extracts the transcript using the Search API.
    2. Script Repurposing: DeepSeek processes the transcript, and the refined script is generated.
    3. Avatar Video Generation: The Heen API takes over, producing the AI avatar video.
    4. Output Management: Finally, details such as the video URL, thumbnail, and status are logged in a Google Sheet for easy tracking.
  • Error Handling:
    The workflow includes mechanisms to handle errors, such as waiting for the AI avatar video to be generated or re-running steps if the network is slow. This ensures that the final output is delivered reliably.
