How to Turn a 16:9 Video into 9:16 Without Cutting Off the Speaker

A wide video and a tall phone screen do not match. The picture you shot in 16:9 has to become 9:16, and how you do it decides whether the viewer sees the speaker or an empty wall. There are three ways to do it. Each is right for some videos.

In short: if one person talks, crop a tall window and let it follow them. If the frame is full of detail, fit the whole picture and fill the rest with a blurred copy. If two people talk, switch the crop between them or stack them.

The three ways

1. Crop and follow

You cut a tall slice out of the wide frame and move it to keep the subject inside. It fills the screen, so faces are large. It works best for a single speaker, a presenter or any scene where one thing matters at a time.

Watch for: a slice that stays in the middle while the speaker walks to the side, or a slice that moves so often that it makes people dizzy. Good reframing moves rarely and smoothly, and cuts when the shot changes.

2. Fit and fill

You keep the whole 16:9 picture in the middle of the vertical frame and fill the empty bands above and below with a blurred, enlarged copy, or a plain colour. It loses nothing from the picture, so it is the right choice for screen recordings, charts and slides where cropping would remove information.

Watch for: small text. A 16:9 screen shown at the width of a phone is small, so zoom into the part that matters instead.

3. Two speakers

When two people talk, the crop has two options: jump between them when the speaker changes, or stack both in one frame, one above the other. Jumping gives larger faces; stacking keeps the conversation visible.

What "auto reframe" does

Automatic reframing looks at the video, finds faces and the moving subject, and builds the crop path for you. Clip-Short does this for each clip: it follows the person talking (using mouth movement when several faces are on screen) and keeps the crop steady between shots. You can still change it: the editor shows the full source with the crop box, lets you pin the crop for a shot and split a shot into two regions.

How to fix a bad crop

1. Find the shot. Scrub through the clip and note where the speaker leaves the frame.
2. Pin the crop to the person for that shot, or move it by hand.
3. Use two regions if two people matter in the shot.
4. Switch to fit and fill for slides and screens.
5. Check on a phone. What looks fine on a desktop preview can have the face under the platform's captions.

Sizes and safe areas

9:16 means 1080 by 1920 pixels for most uses. Platforms cover the bottom and the right side with their own buttons and text, so keep captions and important faces away from those edges. Our video size guide lists the details for each platform.

Questions

Does cropping lower the quality? A crop uses part of the picture, so a low-resolution source looks softer when enlarged. A source recorded in at least 1080p crops well.

Can I get a square or 4:5 clip from the same video? Yes. The same reframing works for other shapes; pick the shape you need before you export.

Do I need to reframe if I filmed vertical? No. Only wide video needs it.
