How to make a video vertical (9:16) on a Mac
Got a landscape clip you want to post as a Reel, TikTok or Short? Here's how to turn it vertical on a Mac in about a minute — without cropping the subject, entirely offline. The trick is a fit-with-blur reframe, not a crop.
The short version
-
Open Crisp → Reframe
Grab the free Crisp app for Mac and open it. Click the Reframe tab in the Tools panel.
-
Pick 9:16 vertical
Choose 9:16 for Reels, TikTok and Shorts. Prefer a square or portrait post? 1:1 and 4:5 are right there too.
-
Drop in your landscape clip
Drag your horizontal video onto the window. Crisp fits the whole frame inside the vertical canvas, nothing gets cropped, and fills the top and bottom bars with a soft, blurred copy of the same footage (the polished Reels/CapCut look).
-
Export
Crisp renders the vertical clip on your Mac and saves it beside the original — ready to post.
Crop vs fit-with-blur — why it matters
A hard crop to 9:16 throws away the sides of your frame and often cuts off heads or action. A fit-with-blur reframe keeps the entire shot visible and uses a blurred version of the footage as a background, so nothing important is lost. That's what Crisp's Reframe does by default.
Want it to look even sharper?
Run Enhance first to upscale and clean the clip up to 4K, then switch to Reframe → 9:16. Two on-device passes, still no cloud and no subscription. You can even just type “make this vertical for TikTok” in Crisp's plain-English box and it sets it up for you.
| Aspect | Best for |
|---|---|
| 9:16 | Reels · TikTok · YouTube Shorts |
| 1:1 | Square feed posts |
| 4:5 | Tall portrait feed posts |
| 16:9 | YouTube · landscape |

Going vertical, in detail
How do I make a video vertical without cropping?
Use Crisp's Reframe lane at 9:16 — it fits the whole frame and fills the bars with a blur, so the subject is never cut off.
Is it free?
Yes — Reframe is in the free tier. Free exports carry a small “Made with Crisp” mark; a one-time $129 removes it. It runs entirely on your Mac.

Crop or pad — pick deliberately
Turning a 16:9 clip into 9:16 means either throwing away the sides or adding bars. Cropping keeps the frame full-bleed and is what social platforms reward, but you lose roughly two thirds of the width, so anything important near an edge disappears. Padding keeps the whole shot at the cost of dead space top and bottom.
The usual mistake is cropping dead centre. Subjects are rarely centred — an interview framed to the left will lose the person entirely on a centre crop. Reposition the crop over the subject before you export, and check the first and last seconds, since people move.
Export at the right size
1080×1920 is the safe target for Reels, Shorts and TikTok. Going higher wastes render time because the platform re-encodes anyway; going lower gets upscaled badly on the platform's side. If your source is 4K, a 9:16 crop still has enough pixels to fill 1080×1920 cleanly.
