AI-powered video generation tools use advanced machine learning models to create or edit videos based on text input, images, or pre-existing video clips. These tools, such as RunwayML, Pictory, Synthesia, and DeepBrain, can generate realistic synthetic videos, animate characters, create deepfakes, or enhance video quality. They allow users to produce videos for various purposes, including marketing, education, entertainment, and social media content, without the need for complex video production skills. Features often include automated script-to-video conversion, voiceovers, AI-driven video editing, and the ability to generate personalized content based on user preferences. AI video generation democratizes content creation by making it faster, easier, and more affordable.
