What Is Auto Reframe?
Auto reframe automatically crops and recomposes a video to a new aspect ratio — like turning a horizontal clip into vertical — while keeping the subject in frame.
Auto reframe is a feature that automatically crops and recomposes a video to a new aspect ratio while keeping the subject in frame. Its most common job: converting a horizontal (16:9) recording into a vertical (9:16) clip for TikTok, Reels, and Shorts — without you manually adjusting the crop.
The problem auto reframe solves
Most source footage — podcasts, interviews, webinars, livestreams — is filmed horizontally. But short-form platforms want vertical. Manually cropping each clip means keyframing the frame to follow a speaker as they move, shot by shot. It’s slow and fiddly, especially across dozens of clips.
Auto reframe automates it. Using AI subject tracking, it:
- Detects the main subject — a face, the action, the moving focus of the shot.
- Tracks them as they move around the frame.
- Adjusts the crop continuously so they stay centered in the new aspect ratio.
Auto reframe in a repurposing workflow
Auto reframe is what makes large-scale video repurposing practical. quso.ai’s AI clip generator reframes your horizontal videos to vertical automatically — tracking the speaker, keeping them centered, and adding captions — so a single horizontal recording becomes a batch of post-ready vertical clips. Filming in 4K gives the reframe even more room to crop cleanly.
