Artificial intelligence has brought in a huge change in video creation in recent years. What used to require professional editing software, animation skills and hours of work can now be done in minutes. Also the industry has seen the introduction of the latest audio to video AI which takes in voice recordings, podcasts, music tracks, and narration and turns them out into very presentable video content with very little input from the user.
As of 2026 creators, marketers, educators, and startups are reporting that they are using AI for video production to scale their output. But not all platforms are created equal. Some do best with realistic avatars, others with animation, lip sync or image based video generation.
