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, with no watermark, entirely offline. The trick is a fit-with-blur reframe, not a crop.

The short version

  1. Open Crisp → Reframe

    Grab the free Crisp app for Mac and open it. Click the Reframe tab in the task switcher.

  2. 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.

  3. 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).

  4. Export

    Crisp renders the vertical clip on your Mac and saves it beside the original — watermark-free and 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.

FAQ

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 and watermark-free?

Yes — Reframe is in the free tier and never watermarks your export. It runs entirely on your Mac.
