MAKE ROOM FOR YOUR VIDEO

How can I make a horizontal video vertical without cropping?

Fit the full horizontal video across a 9:16 canvas and fill the space above and below. Padding or blur reuses existing imagery; AI outpainting generates new surroundings. ExpandClip lets you compare a prepared result and preview the layout of your own clip.

Useful for: A landscape shot whose left and right edges matter in a vertical composition.
Composition tip: Keep Source size at 100% for the largest full-width fit inside a vertical frame.

THREE STEPS TO YOUR COMPOSITION

How to convert horizontal video to vertical

01
Bring your landscape video
Upload an MP4, MOV or WebM, or play the horse example. Original shows the wide source before expansion.
02
Choose a 9:16 composition
The full horizontal shot fits across the canvas. The extra room above and below is where new scenery would be generated.
03
Review the mobile framing
Check the size of the subject and any existing captions. Save your chosen composition and estimate as a draft.

SAME SOURCE. THREE DIFFERENT CHOICES.

Change the format. Choose what you keep.

Compare a 16:9 source in a 9:16 canvas before choosing AI expansion.

LESS OF THE ORIGINAL

Crop to fill

Fills the frame by trimming the edges. Useful when all the important action fits inside the crop.

THE WHOLE SHOT, WITH FILLER

Fit with a blurred background

Keeps the entire source over a blurred copy. A practical option when you only need a different canvas.

SPACE FOR NEW SCENERY

ORIGINAL

THE WHOLE SHOT, NEW SURROUNDINGS

Expand the scene with AI

Plans space for new scenery around the original. AI generation uses credits and the result needs review.

Compare three ways to fit the same shot into a new frame.

Compare cropping, blur and outpainting

Make a landscape video vertical without losing the sides

Keeping the full width can preserve people or products at opposite edges. In a tall canvas, that wide source becomes a shorter band. Compare the subject size with a close crop before choosing the approach for your shot.

Resize video for TikTok, Reels and Shorts

A 9:16 composition is a useful starting point for vertical mobile placements. Review it on a phone, leave important captions clear of interface overlays and check the destination's current upload requirements before publishing.

AI expansion versus auto reframe

Auto reframe often moves a crop to follow a subject. Outpainting adds scene content around the full source instead. The horse example shows added sky and ground; compare the Original and Expanded views at the same playback position.
