Convert Horizontal Video to Vertical: 3 Ways to Reframe
To convert horizontal video to vertical, you have three choices. Crop the 16:9 frame to 9:16 around the subject. Fit the whole wide frame inside a vertical canvas on a background. Or stack two views in the vertical frame. Cropping looks most native when one subject carries the shot. Fitting keeps everything when the whole frame matters. Stacking works when two things happen at once, like a face and a screen. Most edits use a mix, chosen scene by scene.
Why can’t you just rotate or stretch it?
Rotating gives you a sideways video, and stretching distorts every face. A 16:9 frame is almost twice as wide as it is tall; a 9:16 frame is the opposite. You can’t keep the whole picture and fill the screen at the same time. Every method below is a decision about what to keep.
What are the 3 ways to reframe?
| Method | What it does | Best for | Watch out for |
|---|---|---|---|
| Crop and follow | Cuts a vertical slice out of the wide frame, centered on the subject | Talking heads, single-subject action, gameplay with a focal point | Two people far apart; text near the edges |
| Fit on a background | Shows the full wide frame in the middle, with color or blur above and below | Landscapes, slides, wide shots where everything matters | Small picture on a phone; empty bands |
| Stack | Two views on top of each other: a face cam and a screen, or two angles | Reactions, tutorials, podcasts with two speakers | Busy layout; captions crowding the seam |
How do you crop without losing the subject?
The crop is only as good as its center point.
- Pick a focus per scene. A speaker on the left third of the frame needs a crop on the left third, not the middle.
- Move with the action. If the subject crosses the frame, split the scene and give each part its own focus, or use a slow pan.
- Mind burned-in text. Titles and lower thirds near the edges of the wide frame get cut. Re-add them as text in the vertical edit.
- Check faces in the first frame. A crop that clips a forehead in the opening shot reads as a mistake.
When is fitting on a background better?
When the whole frame is the point: a landscape, a product shot on a table, a slide with text, a wide gameplay view where the minimap matters (gameplay highlights covers the game side). Make the empty bands work for you:
- Put the title in the top band and captions in the bottom band, so nothing covers the picture.
- Use a solid color from your brand or a dark neutral rather than a loud color that competes with the video.
When should you stack two views?
When the story needs both at once: a gamer and the game, two podcast hosts, or a hand and the screen it’s tapping. Stack them top and bottom in the vertical frame, each cropped to its subject. Keep captions off the seam between the two. This is the usual layout for podcast Shorts with two hosts.
In Cut Express this is a picture-in-picture overlay: one video fills the frame, the other sits on top in a rounded box anywhere you place it.
How does Cut Express convert horizontal video to vertical?
Ask for 9:16 and say what to keep. Claude chooses the method per scene, with the tools listed under features:
- Crop and follow. Each scene can set a focus point for the crop, and a slow pan when the subject moves. Claude reads the contact sheets to see where the subject sits in each shot.
- Fit on a background. A scene can fit the whole frame inside the vertical canvas, on a background color you pick.
- Stack. An overlay places a second video (or the same one, cropped differently) on top, with rounded corners.
- Re-add the text. Text boxes and captions are placed for the vertical frame, inside the safe area.
A prompt that works:
“Make a 9:16 version of this interview. Crop on whoever is speaking, fit the slide scenes on a dark background with the title above, and put my face cam in the top corner during the screen recording.”
You can also go the other way: a 16:9 cut of a vertical edit is the next version of the same video. Pro renders 1080p, Ultra renders 2K for both shapes (pricing).
What resolution should the vertical version be?
1080 by 1920 is the standard vertical size for short-form apps. Cropping a 1920 by 1080 source down to vertical leaves a slice about 600 pixels wide, which then gets scaled up. That’s usually fine on a phone, but it’s softer than native vertical footage. If you film for both shapes often, shoot 4K and crop from that.
FAQ
Will an automatic center crop work?
For one person in the middle of the frame, yes. For two people, a moving subject or text at the edges, no. Set the focus per scene.
Can I mix methods in one video?
Yes, and you usually should: crop the talking parts, fit the wide shots, stack the screen recordings.
What about captions?
Put them where they don’t cover faces, usually the lower third or the bottom band. See captions for Reels.
Do I need to re-upload the video?
No. A new format of an existing edit renders from the same media. See how it works.
