AI images, video and voice: how they are made
How image generators, video models and voice cloning actually work, how to prompt them, where deepfakes come from, and the legal rules for using AI images.
An image generator does not paste together pictures it has seen. It starts from random noise and removes it step by step until what is left matches your description, and the same broad idea now drives generated video clips and cloned voices. That is worth understanding whether you want to make this material yourself or you simply want to know what is possible when a video of somebody you know arrives on your phone.
Read how noise turns into a picture for the mechanism, then how to describe subject, style, light and framing, which is a different craft from writing text prompts. Generated video covers what current models manage and what still gives them away, and voice cloning explains how a few seconds of recorded speech becomes a convincing phone call.
Before you publish anything you generated, check the ground you are standing on. Rights, credit and the safe path for AI images matters far more to a business putting pictures on a product page than to somebody making a birthday card.
