In the world of TikTok, Reels, and YouTube Shorts, capturing attention within the first three seconds is crucial. Dynamic effects like zooms are no longer optional—they're essential for keeping your audience hooked. But how do you add them quickly and effectively?
One of the most talked-about tools for short-form video is Submagic, an AI-powered engine designed to make your clips go viral. But how does it handle zoom effects?
This article will reveal how Submagic uses AI to automatically add zooms to enhance your video's rhythm. Then, for moments that require more precise, controlled motion—especially in tutorials and product demos—we will introduce a perfect complementary tool.

When is Submagic's AI Zoom Perfect?
- Talking-Head Videos: It’s brilliant for adding energy to a static shot of someone speaking, keeping the viewer engaged.

The Limitation: When You Need Precise Control
But what if you need to zoom in on a specific button in a software demo? Or what if you need a slow, cinematic zoom to showcase a physical product's details? This is where an automatic, AI-driven zoom falls short. For that, you need a manual tool.
