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.

Frequently Asked Questions

What is auto reframe?+
Auto reframe is a feature that automatically converts a video from one aspect ratio to another — most often horizontal (16:9) to vertical (9:16) — by intelligently tracking the subject and cropping the frame so the action stays centered.
Why is auto reframe useful?+
It removes the tedious manual work of recropping footage for each platform. Instead of keyframing the crop yourself to keep a moving subject in shot, auto reframe follows the subject automatically — essential for repurposing horizontal video into vertical clips at scale.
How does auto reframe keep the subject in frame?+
It uses AI to detect and track the main subject — a speaker's face, the action, the moving object — and continuously adjusts the crop so they stay within the new frame as they move.
