What is AI Video Generation?
AI video generation is a revolutionary technology that uses artificial intelligence to create videos from text descriptions or images. Unlike traditional video production, it requires no expensive equipment, professional editing skills, or filming teams.
Since 2023, this technology has made breakthrough progress. Companies like Runway, Pika Labs, and Nano Banana have launched text-to-video products that can generate near-cinematic quality videos in just seconds.

A focused example: a two-photo zombie reunion
If your goal is the zombie hug trend, a fixed story can be easier to use than a blank prompt. Zombie Trend Video takes two separate adult portraits: the first person stays human and the second becomes the returning zombie. Its classic scene follows tearful hesitation, happier memories, and a final embrace, with the human character's expression at the center.
- Watch the generated example and choose photos you have permission to use.
- Choose a vertical 9:16 or wide 16:9 frame and review the current one-time price.
- Follow generation in My films, then review and download the 15-second HD MP4 with music.
This is a separate paid service, starting at $3.99 per video as of October 20, 2026. Faces and motion can vary between AI-generated results; the preview shows the intended style.
