A Guide to Creating Cinematic Videos with AI Consistent Talking Characters

Let’s start with how to create realistic talking AI characters using powerful tools like Flux and Replicate. 

Step 1Create AI Characters

In the first step, we will discuss how you can create an AI character. There are several AI generation tools, such as Flux 1.1, Midjourney, Runway, Pixray, and Fotor AI to choose from. In this guide, the AI character has been created through Flux 1.1.

• Select the Input as Form and describe the character you want to create in the  Prompt box on the left panel. Be specific about the character’s outfit, expressions, and the setup you want as background. 

The idea behind this video was to recreate Greek gods and place them in a corporate setting. So, you’ll find different characters representing mythological gods in this tutorial. Here’s Aphrodite, the goddess of love and beauty, reimagined and designed through Flux 1.1.

Step 2Design Diverse Perspectives for the Character 

Once you have created the character, the next step is to create multiple consistent images of the same character. For this, we will use Replicate’s consistent character tool. It allows you to create images from different angles and perspectives. You can use the same prompt you used in Flux 1.1 to generate multiple images of your character in Replicate.

• If you want to create a video with more than one AI character, follow the same steps outlined above to design other characters for your content. Have a look at how another character, Zeus, was reworked into different perspectives with Replicate.

  

You don’t have to limit yourself to just a few images. If you like a particular angle, save it, and create more images by changing your input image and prompt.

Step 3Train A Model

• In this step, we will head over to fal.ai and start training the AI characters for seamless video content. Select the Playground tab and upload the images of an AI character you created previously with Replicate. Enter a Trigger Word and click Start to get the ball rolling.

  

Step 4Describe A Video Scene

Once your model is completely trained, you can move on to the next step of creating different scenes. Start by entering a relevant prompt for the scene and setting the scale of your video. 

You don’t need to go into a lot of detail when writing the prompt since you already have a trained model. Simply add a few trigger words, such as what the character is doing, the scene behind them, etc.

• Click More from the bottom for additional settings. Set the guidance scale and the number of images you want and click Run.

  

Step 5Make Your AI Characters Talk

After creating multiple scenes with your AI characters, it’s time to make them talk. For this step, we will use Virbo Talking Photo. an efficient and intuitive solution for make your consistent characters talk.
