Keywords

💡AI Avatar

An AI Avatar refers to a digital representation of a human, generated using artificial intelligence technology. In the video, the process of creating a realistic, AI-generated human likeness is discussed, including capturing facial and body movements. The AI avatar can then be used to deliver messages or perform tasks in a realistic and engaging manner, as demonstrated by the script where the creator reads a teleprompter to train the avatar's facial expressions and movements.

💡Synthesia

Synthesia is the company behind the technology used to create AI avatars in the video. It is responsible for the entire process, from capturing the human likeness to processing the data and creating the final AI avatar. The script mentions a visit to Synthesia's London studio where the visual and audio capture takes place, highlighting the company's role in the creation of these digital personas.

💡Teleprompter

A teleprompter is a device used in video production to display a script for the speaker to read while looking directly at the camera. In the video, the creator uses a teleprompter to read scripts that will be used as training data for the AI avatar. This helps capture the speaker's facial expressions and body language, which are crucial for creating a realistic and engaging digital representation.

💡Green Screen

A green screen is a technique used in film and video production where a solid color (usually green) is used as a background, which can then be replaced with any other image or video during post-production. The script mentions that makeup is applied to reduce shine, which is important when filming in front of a green screen to avoid unwanted reflections that could interfere with the keying process.

💡Post-production

Post-production refers to the process of editing and refining a film or video after the initial shooting has been completed.
