How is this better than pausing the video and using Cmd-Shift-4?

A screen capture grabs only what's on screen — scaled down to your display, plus any player UI — and it's hard to land on the exact frame. Crisp reads the real frame straight from the file at full resolution, at the exact time you type, with nothing else in the shot.

Can I grab the very first or last frame?

Yes. Type "grab the first frame" or "save the last frame", or leave the time blank for the first frame. Crisp lands on a real frame near the end rather than overshooting into an empty grab.

Is my video uploaded anywhere?

No. Crisp grabs the frame entirely on your Mac — nothing is uploaded, so there's no queue, no size cap, and your footage never leaves the device.

How to take a screenshot from a video on a Mac

Grabbing a clean still frame from a video — for a thumbnail, a poster, or just to save a moment — shouldn't mean pausing the clip and screenshotting your screen (which only captures what's visible, scaled down, with the player's buttons in the shot). Here's how to take a screenshot from a video on a Mac at full resolution, at the exact time you want, 100% offline — PNG or JPG, no account, no upload.

Updated July 2026 · step-by-step

The fastest way: just ask

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

grab a frame at 3 seconds — a still at exactly 3s
take a screenshot — a still from the clip
save the last frame — the final frame
grab the first frame — the opening frame
make a thumbnail — a still to use as a cover
export a frame as a jpg — a smaller JPG instead of PNG

Crisp reads the request, switches to the Frame lane and fills in the time and format — you just press the button. It's careful about intent, too: merely describing the footage ("the thumbnail looks bad", "the first frame is black") won't trigger a grab, and "grab a frame and upscale it" lets the bigger job take over.

The manual way: the Frame 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.
Pick the Frame lane

Choose Frame (the 📸 button) in the task row.
Set the time and format

Type the time in seconds to grab (leave it blank for the first frame). Pick PNG for a lossless still or JPG for a smaller file.
Press Grab frame

Crisp saves a full-resolution still image at that moment beside your original, on-device. HDR clips are tonemapped so the still keeps its colour — no washed-out grab.

The real frame, not your screen

A screen capture (Cmd-Shift-4) only saves what's on your display — scaled to the window, often with the player's controls, and it's fiddly to land on the exact frame. Crisp reads the frame straight from the video file at its native resolution and at the precise time you type, so you get the whole picture and nothing else. Grabbing the last frame works too — Crisp lands on a real frame near the end instead of overshooting into an empty grab.

PNG or JPG?

PNG is lossless — a pixel-perfect copy of the frame. Best for editing, crisp text/graphics, or a poster you'll re-encode later. It's the default.
JPG is smaller at a slight quality cost — fine for sharing or a quick thumbnail.

Crisp vs QuickTime vs iMovie vs online tools

	Crisp	QuickTime (Cmd-Shift-4)	iMovie	Online frame grabbers
Full-resolution frame (not screen-scaled)	Yes	No — display-scaled	No export	Varies
Exact timestamp	Yes — type it	Manual pause	Manual	Manual
No player UI in the shot	Yes	Often	—	Yes
PNG (lossless) option	Yes	Yes	—	Varies
100% offline, nothing uploaded	Yes	Yes	Yes	Uploads your clip
Price	Free during beta	Free	Free	Free + upsell

iMovie has no "export this frame" at all; QuickTime only screenshots your screen. For the actual frame at full quality, Crisp reads it from the file locally.

Why offline matters for grabbing frames

Your footage stays yours. The "grab a frame online" tools upload your clip first. Crisp reads it entirely on your Mac — nothing leaves the device.
Full resolution, exact time. No display scaling, no player chrome, no guessing where to pause.
HDR handled. A 10-bit / HDR clip is tonemapped so the still doesn't come out washed-out.
No queue, no size cap. It reads the frame instantly from the local file.

Grab your first frame — offline

Free to try on your Mac. Type a time, pick PNG or JPG, export a full-resolution still — no account, no upload, nothing leaves your device.
