💡Stable Video Diffusion

Stable Video Diffusion (SVD) is an AI tool developed by Stability AI for generating videos. It creates lifelike and captivating videos from text descriptions or still images. The technology builds upon the original stable diffusion model, starting with a noisy input and refining it to produce clear and realistic videos. In the video, SVD is highlighted for its ability to create videos with moving elements and facial expressions, showcasing its impact in the AI and tech world.

💡Foundation Model

A foundation model in the context of the video refers to a core AI model that serves as a basis for various applications. Stability AI's first foundation model for generative video, SVD, demonstrates the company's advancement in AI technology. It signifies a shift towards more complex and versatile AI applications, which can be adapted for different purposes, such as creating videos from text or images.

💡Generative Video

Generative video is a term used to describe the process of creating new video content using AI.
