Keywords

💡Stable Video Diffusion

Stable Video Diffusion is a technology released by Stability AI that enables the transformation of still images into dynamic videos. It is based on the image model of Stable Diffusion and is adaptable to various video applications, including multi-view synthesis. In the video, it is demonstrated how this technology can take a prompted or regular photo and create a cool video output, showcasing its capability to generate videos from images of different resolutions and content.

💡Generative Video

Generative Video refers to the creation of new video content that did not previously exist. In the context of the video, Stable Video Diffusion is a generative video model, meaning it can generate new video frames based on an initial image input, effectively 'animating' the image to create a video sequence.

💡Multi-view Synthesis

Multi-view Synthesis is a process where an image is manipulated to give the impression of being viewed from multiple angles, as if it were a 3D model. The video demonstrates this by showing how an image can be turned into a sort of 3D model that can be spun around to view from different perspectives.

💡Frames

In the context of video, frames refer to the individual images that make up the video when played sequentially. The video mentions two models for Stable Video Diffusion, one for 14 frames and one for 25 frames, indicating the length of the video generation run.
