Detailed Explanation of AI Video Generation
AI video generation is a general term covering the process of creating new video content from various inputs (text, images, audio, existing video) using AI technologies. This field brings together text-to-video, image-to-video, video-to-video, and AI avatar technologies under one umbrella.
Sub-disciplines of AI video generation include: txt2vid (text to video), img2vid (image to video), vid2vid (video-to-video transformation), AI avatar (digital talking humans), AI animation (animating static images), and AI video editing (processing existing videos with AI).
