Definition: AI video generator

An AI program that generates a relatively short video from text descriptions. Some AI video generators accept text for each scene, while others generate a video based on a short text description similar to AI image generators. There are several generators on the market, but when Meta Platforms (Facebook) announced its Make-A-Video offering in 2022, more people became aware of the process.

For scene-by-scene generators, various amounts of customization are provided such as backgrounds, fonts, colors, resolutions and aspect ratios. Both free and paid versions are typically available, although some paid-only generators are aimed at enterprises. See Sora AI, virtual newscaster, AI image generator and AI text generator.

A Reals Video

In this scene-to-scene example, in which a plain background was selected, the woman is speaking with simulated mouth movements synchronized to the text. In the 2020s time frame, text-to-video generators followed on the heels of text-to-image generators. (Image courtesy of Reals.ai.)

A Phenaki Video

The Phenaki generator offers a variety of text-to-video options. In this example from the Phenaki website, the selection of "cartoon on Mars with earth in the background" produced these scenes which are animated on the Web page. (Image courtesy of Phenaki.video.)
