How to add a vignette to a video on a Mac

A vignette softly darkens the edges of the frame so the eye is pulled to the centre — it's one of the quickest ways to make a clip look cinematic and film-like. Here's how to add a vignette to a video on a Mac in one tap, 100% offline: the whole picture stays, and there's no account, no upload, no watermark.

The fastest way: just ask

Crisp has a plain-English box ("Or just tell Crisp what to do…"). Drop your video in and type it:

• add a vignette — the classic soft-dark-edges look
• darken the edges — same effect, plain words
• give it a vignette — Crisp reads it either way
• add a subtle vignette — a gentle, understated falloff

Crisp reads the request, switches to the Color lane, and turns the vignette on — you just press the button.

Step by step: the Color lane

1. Open Crisp and drop in your video

   Get the free Crisp app for Mac and drag your clip onto the window. Nothing is uploaded — the whole job runs on your Mac.

2. Ask for a vignette (or open the Color lane)

   Type add a vignette, or choose Color in the task row. Crisp turns the vignette on.

3. Press it

   Crisp darkens the frame gradually toward the corners while the centre stays bright — a soft, natural falloff, not a hard black ring.

4. Save

   The graded clip lands beside your original — watermark-free.

Vignette vs Border vs Crop

Three edge-related tools, three different jobs:

• Vignette — softly darken the edges (lighting). That's this guide.
• Border — paint a solid coloured margin around the video. See add a border.
• Crop — trim the edges off. See crop a video.

Stack it with a look

The vignette lives in the same Color lane as Crisp's one-tap looks, so you can grade the colour and darken the edges in one pass — a moody or cinematic grade with a vignette reads instantly as "shot on something nicer than a phone". Add a little film grain too and it's a full retro-film treatment, all on-device.

Crisp vs iMovie vs online vignette tools

	Crisp	iMovie	Online tools
One-tap vignette	Yes	No direct control	Varies
Grade + vignette in one pass	Yes	Fiddly	Rarely
Plain-English request	Yes	No	No
100% offline, nothing uploaded	Yes	Yes	Uploads your clip
Price	Free during beta	Free	Free + upsell

iMovie has no direct "vignette" control (you'd overlay a darkened shape); online tools upload your footage first. Crisp adds a real vignette in one tap and keeps it local.

Why offline matters

• Your footage stays yours. The "add vignette to video online" tools upload your clip first. Crisp does it on your Mac.
• No queue, no size cap. It works on the whole file locally.
• Fast. HEVC hardware encoding on Apple Silicon.
• Stack it. Grade the colour, add a vignette, add grain — all on-device.

FAQ

How do I add a vignette to a video on a Mac for free?

Use Crisp: drop your clip in and type "add a vignette" (or open the Color lane). It darkens the edges toward the corners on your Mac — no account, no upload, no watermark.

Does it crop or shrink the video?

No — a vignette only darkens toward the edges. The frame stays the same size and every pixel is still there. It's lighting, not a crop.

Can I combine it with a colour grade?

Yes — the vignette is part of the Color lane, so you can apply a look (cinematic, moody, warm…) and the vignette in the same pass.

Is my video uploaded anywhere?

No — it's all done on your Mac, so there's no upload, no queue, no size cap.
