NotebookLM & Heygen: Creating AI Video Avatar Podcasts Tutorial

Howto & Style

Introduction

Welcome back to AI Motion Studio! Today, we're diving into something incredibly exciting: how to create your very own video podcast powered by AI. If the thought of creating a professional-quality podcast has felt overwhelming due to the technical details, worry no more! In this guide, we'll walk you through the process of creating a captivating AI-powered video podcast using two remarkable tools: NotebookLM and Heygen.

Step 1: Generate Content with NotebookLM

First up, let’s talk about NotebookLM, an innovative AI tool developed by Google that is a game-changer for content creators. NotebookLM can analyze various sources, including articles, websites, PDFs, Google Docs, and even YouTube videos. It processes the information and allows you to generate a variety of content outputs—from summaries to timelines, and even full audio overviews.

For example, if you want to create a podcast episode about Tesla's new robot, simply upload related YouTube videos into NotebookLM. The AI works its magic to create an audio overview that serves as the backbone of your podcast. You can easily customize this content, and NotebookLM will provide a well-researched script that you can download as audio—essentially creating a podcast episode in minutes instead of hours.

Step 2: Bring Your Content to Life with Heygen

Now that you have your audio ready, it’s time to visualize it using Heygen. This AI video creation platform allows you to bring your audio content to life with realistic avatars. You can select avatars that match the tone of your podcast and upload the audio file generated from NotebookLM.

Bear in mind that Heygen has a 3-minute limit per audio file, so if your podcast exceeds this duration, you’ll need to split the audio into smaller chunks. Once you upload the audio, Heygen synchronizes the avatars' lip movements with the audio seamlessly.

For this example, I chose both a male and a female avatar to represent the speakers. After rendering the videos in 720p, I upscaled the resolution to 4K using Topaz Video AI. The process is straightforward: just upload your videos, use the default settings in Topaz, and export the enhanced visuals.

Step 3: Edit Your Podcast with CapCut

Next, it's time to assemble everything using a video editing tool like CapCut. (Feel free to use any video editing software you prefer.) Here’s how I arranged my content: I placed the two avatars on screen, reacting to each other, while adding b-roll, text overlays, and background visuals to enhance engagement.

Using the green screen feature in Heygen, I replaced the avatars' plain backdrop with a more dynamic background, which adds creativity to the podcast. After arranging all the components, I exported the final video package.

Final Thoughts

In just a few easy steps, you can create an entire video podcast using the combined powers of NotebookLM for content generation and Heygen for visual representation. These tools save you considerable time and effort while allowing you to produce high-quality, engaging audio-visual content. Whether you’re a seasoned content creator or just starting out, this method has made podcast creation more accessible than ever.
