9:16 reframe

Naive center-crop fails on talking-head content as soon as the subject moves. A simple algorithmic crop will clip half a face when someone leans forward, or center the cut on a static prop while the speaker sits to one side.

Real reframe uses face-tracking to follow the subject across the frame and lock the crop window to them. When two subjects appear (interview format), the system splits the screen vertically — speaker A on top, speaker B on bottom — so both stay visible.

• Subject is centered horizontally regardless of where they sit in the original frame.
• Crop window moves smoothly when the subject moves, with no jarring jumps.
• Two-speaker interviews split the frame instead of bouncing the crop between speakers.
• Captions sit in the lower third without overlapping the subject's face.

When a reframe looks off, the cause is usually one of three things: face-tracking lost the subject during a fast movement, a graphic on screen confused the algorithm into tracking the graphic instead of the speaker, or the source video had a horizontal-only composition (text running across the bottom) that doesn't survive the crop.
