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
-
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.
-
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.
-
Press it
Crisp darkens the frame gradually toward the corners while the centre stays bright — a soft, natural falloff, not a hard black ring.
-
Save
The graded clip lands beside your original — one-time.
A vignette is lighting, not a crop
A vignette only changes brightness toward the edges — the frame stays exactly the same size and every pixel is still there. That's different from Crop (which trims the edges off) and from Border (which paints a solid margin around the picture). Crisp uses a smooth radial falloff so the darkening looks natural, the way a real lens vignettes.
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.
What the strength slider actually is
A vignette is not a black oval pasted on the corners. Crisp's is modelled on the thing that causes it in a real camera — the aperture angle of the lens — and the slider moves that angle from about 30° at the subtle end to about 60° at the strong end. That is why it falls off smoothly into the picture instead of showing an edge, and why it follows the frame's shape rather than needing to be re-drawn for a portrait crop.
It is also the last step in the colour chain, applied after exposure, contrast, saturation and any grain. That ordering is what lets a vignette combine with a look instead of fighting it: darkening the corners of an already-graded picture reads as light falloff, while grading an already-darkened picture lifts the corners back up and you lose the effect you asked for. So "cinematic with a vignette" composes correctly, and so does a vignette on top of grain.
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 tier + one-time $129 · or 4 × $32.25 | 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.

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.
