The Problem: Bad Framing Kills Clips
You recorded a great podcast moment. But when you crop to 9:16, the speaker is half off-screen. They lean left—now they're cropped out entirely. Manual reframing takes forever.
Sintorio's Active Speaker Detection fixes this automatically. Our AI tracks faces in real-time and keeps the speaker perfectly centered—even when they move, gesture, or lean.
How It Works
Face Detection
AI scans every frame to detect all faces in the video using MediaPipe's state-of-the-art detection.
Speaker Identification
Audio analysis and lip-sync detection determine who is speaking at each moment.
Dynamic Framing
The frame smoothly tracks the active speaker, maintaining proper headroom and composition.
Smooth Transitions
When speakers change, the camera pans smoothly—never a jarring cut. Professional results.
Perfect For
Two-Person Podcasts
Host and guest go back and forth. AI tracks the conversation and shows whoever is speaking.
Interview Clips
Interviewer asks, guest answers. The frame follows the conversation naturally.
Panel Discussions
Multiple speakers on screen. AI handles 3, 4, even 5+ people switching between speakers.
Solo Content
Even solo creators benefit—speaker stays centered when moving, gesturing, or pacing.
