The Problem: Raw Clips Don't Go Viral
A clip with no captions, static framing, and zero movement? That's a scroll-past. The clips that blow up have dynamic edits, punchy captions, and perfect framing. That takes hours in editing software—or an expensive editor.
Sintorio's Virality Engine does it automatically. Face tracking, animated captions, smart zooms—all applied instantly using AI. Your raw footage becomes scroll-stopping content in seconds.
What the Virality Engine Does
Active Speaker Detection
AI tracks who's talking and automatically centers them in frame. In multi-person videos, it switches between speakers seamlessly.
Dynamic 9:16 Cropping
Horizontal video becomes vertical shorts with intelligent reframing. Subjects stay centered even when they move.
Animated Captions
Captions synced to the millisecond with bounce, fade, and highlight effects. 85% of videos are watched on mute—captions aren't optional.
Smart Zoom Effects
AI adds zoom-ins on emotional peaks, reactions, and key moments. The subtle movement keeps viewers engaged.
