Video Summary
This video demonstrates a step-by-step process for creating highly realistic, professional-looking AI-generated videos using a custom character and script.
The video summary is as follows:
- Objective: The creator shows how to combine four separate images (a man, a uniform, a product, and a background) into a single, cohesive, lip-synced AI video [00:00].
- Image Generation with Flux Context: The first step involves using Open Art AI’s Flux Context Max with its multiple image reference feature. The user uploads the four source images and uses a prompt generated by ChatGPT to create a single, consistent composite image of a doctor holding a vitamin bottle in a hospital setting [01:43].
- AI Video Creation with HeyGen: The generated image is then uploaded to HeyGen AI, specifically utilizing the latest Avatar 4 model, which is capable of producing human-like emotions and gestures [04:02].
- Voice and Script: A custom script is typed in, and a voice is selected from HeyGen’s built-in options, which the tool helps match to the character in the image [05:33].
- Enhancing Realism: A key instruction is to enable the “more expressive” feature in HeyGen, which adds realistic body language and gestures, significantly reducing the “AI feel” in the final video [07:11].
- Results: The creator showcases the final product, which is a highly realistic, lip-synced testimonial, and compares it to other variations to highlight the importance of the expressive setting [08:01].
