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.

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 Tools panel. 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 — one-time.

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

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.

Vignette questions

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. Free exports carry a small “Made with Crisp” mark.

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.

Keep it below the threshold of notice

A vignette works when the viewer's eye is pulled to the centre without registering why. Once someone can see a dark ring, it stops reading as cinematography and starts reading as a filter. If you can point at where it begins, it's too strong.

Watch for banding on flat backgrounds. A gradual darkening across a plain sky or wall is exactly the case where 8-bit video shows visible steps, and a vignette is a large smooth gradient by definition. Keep the falloff wide and the strength low.

Shape and centre matter more than strength

A circular vignette on a 16:9 frame darkens the corners unevenly, because the frame is much wider than it is tall. An elliptical shape that follows the frame's aspect keeps the falloff even along the top and bottom edges, which is why it reads as lighting rather than as a filter laid over the top.

Off-centre subjects need an off-centre vignette. If your subject sits a third of the way in, a centred vignette darkens their face while brightening empty background — the exact opposite of what you wanted. Move the centre to the subject.

When to skip it entirely

Vignettes fight against footage that already has strong natural falloff, such as a subject lit by a single window against a dark room. Adding one there just crushes shadow detail that was doing the job already. They also stack badly across cuts: a vignette on every clip in a sequence becomes visible the moment two shots sit side by side.
