By 2025, the world of digital marketing has a new sunrise—AI avatar-based video advertising. Gone are the days when a brand would spend money on costly studios, actors, or editing time to create high-converting video commercials. Now, with AI, you can automatically create high-converting video commercials with realistic, custom avatars, which are socially optimized on media such as Instagram, TikTok, Facebook, and YouTube Shorts.
Here, in this guide, we talk about how AI is transforming the production of video ads, what tools to use, and how businesses are capable of creating content faster than ever with voice synthesis and customized avatars.
