An AI video generator is software that uses artificial intelligence and machine learning to create video content from text, images, or audio inputs without the need for traditional video production. The user typically provides a script or prompt, and the tool generates visuals, voiceover, subtitles, and transitions automatically. Tools like Synthesia, Pictory, and InVideo AI are popular examples. For South African businesses, these tools reduce the cost and time involved in producing professional video content for marketing, training, and communications.
