AI video generation (making short videos from text or images)
Japanese 動画生成AI（文章や画像から短い動画を作るAI）
AI video generation tools make a new short video from a written description or a picture. These services often change or shut down, so save the videos you make and check the terms of use.
AI video generation tools take a written scene, such as "a cat walking under a sunset sky," or a single picture, and make a short moving video that matches it. It is like asking a painter who draws from your description to paint a picture that moves. Some models, such as Google's Veo, now also create sound like sound effects and dialogue together with the video.
Watch out These services change or shut down often. OpenAI ended the Sora website and app, and its video features for developers were also removed. If you plan to use a video to promote your shop, download it right after you make it, and check each plan's rules on commercial use and watermarks first. If a video looks like a real person, say clearly that it was made with AI.
