Keywords

💡Stable Video Diffusion

Stable Video Diffusion refers to an AI-based technology that generates video content from static images. It is a method used in the field of generative AI, where the AI model, through training, learns to create smooth and coherent video sequences from a single input image. In the context of the video, Stable Video Diffusion is the core technology being discussed and compared between different versions, with the aim of assessing the improvements and effectiveness of the updated 1.1 model.

💡AI

Artificial Intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think and learn like humans. In the video, AI is the underlying technology for Stable Video Diffusion, where machine learning models are fine-tuned to generate video content.
