How to Screen Record in 4K on Mac (and When It's Real)

To screen record in 4K on a Mac, the screen you capture must render at least 2160 pixels tall. On a Retina display, that means a scaled resolution that "looks like" 1080 points tall or more. The built-in Screenshot toolbar (⇧⌘5) records at your display's full pixel resolution, so on the right setting it already gives you a 4K-sized file. If you want a 4K screen recorder for Mac that also lets you choose 60 fps, compression and an exact export size, use a dedicated app such as Screen Bolt.

If your display renders fewer pixels than that, a "4K" file is upscaled. It has more pixels but no extra detail.

Check whether your display can give you real 4K

macOS lays out the interface in points. A Retina display draws each point with 2×2 pixels. When you pick a scaled resolution in Displays settings, macOS renders the screen at twice the "looks like" size and fits that image to the panel.

A recorder that captures the rendered image gets twice the "looks like" size in each direction:

The rule: your capture needs a "looks like" height of 1080 points or more. The same rule applies to a single window or a dragged area. A window 800 points tall records at 1600 pixels tall, whatever the display is.

To raise the capture size, open System Settings, click Displays, and pick a resolution closer to More Space. Everything on screen gets smaller, including the text in your recording. Check that it is still readable once the video is scaled down for viewers (how to make text readable in screen recordings).

Standard-density (non-Retina) monitors

A typical 1080p or 1440p external monitor runs at one pixel per point, so its real detail stops at its native resolution. A 1920×1080 monitor can't give you real 4K, and any 4K file made from it is upscaled.

In Screen Bolt this matters because the app sizes every capture at 2× the size in points and assumes a Retina display. On a standard-density monitor, the recording can come out larger than the panel's real pixel count without any extra detail. Export at 1080p in that case. Original and 4K would only give you a bigger file that is no sharper.

Record in 4K with the built-in Screenshot toolbar

macOS has a free recorder built in. It is enough if you only need a full-resolution file of the screen.

1. Press ⇧⌘5 (Command-Shift-5).
2. Click Record Entire Screen or Record Selected Portion in the toolbar.
3. Click Options to pick where the file is saved and which microphone to use.
4. Click Record.
5. To stop, click the stop button in the menu bar or press ⌃⌘Esc (Control-Command-Escape).

QuickTime Player's File ▸ New Screen Recording opens the same toolbar. The recording is a .mov at your display's full pixel resolution. On a display set to look like 1920×1080, that file is 3840×2160.

What the built-in method can't do:

• It has no resolution, frame-rate or compression settings.
• It can't record a single window on its own, only the whole screen or a fixed area.
• It records your microphone but not system audio (how to record internal audio on Mac).
• It has no editing beyond trimming. To get a standard size, open the file in QuickTime Player and use File ▸ Export As to save a smaller copy.

For more on this route, see QuickTime screen recording on Mac.

Use a 4K screen recorder for 60 fps and fixed export sizes

We make Screen Bolt, a Mac screen recorder with a timeline editor. It helps here because you choose the frame rate, the compression and an exact export size, and the 4K export already includes your auto zooms, background and webcam overlay.

1. Click the gear in the recording bar (or press ⌘, (Command-Comma)) and open the Quick export tab.
2. Set Frame rate to 60 FPS (the default) or 30 FPS. This setting controls the recording itself, so choose it before you record.
3. In the recording bar, choose Display, Window or Area. With more than one monitor, Display becomes a menu listing each screen (how to screen record one monitor on a Mac).
4. Click the red record button.
5. Click Stop when you're done. You can also press ⌃⌘↩ (Control-Command-Return) while Screen Bolt is the active app.
6. In the editor, click Export.
7. Under Format, choose MP4 (H.264) or MOV (HEVC).
8. Under Quality, choose 4K or Original. Each tile shows its output size in pixels.
9. Check the summary line and the Save to folder, then click Export. Exports above 720p need a license. The free version records without limits, but its exports are capped at 720p and 3 minutes and carry a "Made with Screen Bolt" watermark. Screen Bolt Pro is a one-time $79 purchase as of November 2026 (Free vs Pro).

How Screen Bolt sizes the capture

Screen Bolt records at 2× the source size in points, in the Display P3 color space, as H.264 inside a .mov, with 48 kHz stereo audio.

• Display records the whole screen at 2× its "looks like" size.
• Window records only that window at 2× its size, even if other windows cover it. For a 2160-pixel-tall capture of a browser, the window itself must be at least 1080 points tall.
• Area records the rectangle you drag at 2× its size, so a small area won't reach 4K.

To see your exact capture size, open the Export sheet after a short test recording. The Original tile is the full capture, and any preset larger than the recording is disabled.

Why a big capture helps even for a 1080p export

Zooms crop into the capture. At the default 2.0× zoom level, a 3840-pixel-wide capture still has 1920 real pixels across the zoomed view, enough to fill a 1080p frame without upscaling. A 2880-pixel-wide capture zoomed to 2.0× has only 1440 pixels across, so a 1080p export of that zoom is slightly soft. If you zoom a lot, record at a high "looks like" resolution even when you plan to export at 1080p. See how to zoom in on a screen recording for zoom settings.

30 vs 60 fps screen recording on Mac

In Screen Bolt, Frame rate (30 FPS or 60 FPS, default 60) applies to recording, quick export and editor export. A recording made at 30 fps does not get smoother when exported at 60, so set it before you record. If you recorded at 60, check it is still on 60 when you export.

Pick 60 fps if:

• Your video has fast cursor movement, scrolling, drag-and-drop or UI animations.
• It's a product demo or launch video where smooth motion matters.

Pick 30 fps if:

• The video is mostly slow, static screens such as settings walkthroughs or documentation.
• Your Mac reported dropped frames at 60 fps (see troubleshooting below).

Export at 4K or Original

The Quality options are:

Two things to keep in mind:

• Width follows the video's shape. Mac displays are often 16:10, so a 4K export of a full display can be narrower than 3840. If you need a 16:9 frame, set Canvas ▸ Aspect Ratio to 16:9 in the Screen panel, then check the 4K tile's pixel size before exporting.
• The Export sheet won't go above your recording. If the recording is smaller than a preset, that tile is disabled with the note "Recording is W×H — this preset would not scale down." Choose Original instead. Upscaling in another app adds pixels, not detail.

If you set After recording to Export to file in Settings ▸ Recording, Screen Bolt skips the editor and uses the Resolution from the Quick export tab (720p, 1080p or 4K). Every editor export updates that setting. A quick export uses default styling with no background, saves the file inside the project, and in the free version fails without a message if the recording is longer than 3 minutes.

The export help page covers formats, presets and free-version limits in more detail.

Compression and file size

Screen Bolt bases the bitrate on the number of pixels. The Compression setting in Settings ▸ Quick export then scales it, for quick exports and editor exports alike:

The setting's note says "Quality setting does not impact export speed," so a higher setting costs disk space, not time.

From those rules you can estimate relative sizes:

• 4K has four times the pixels of 1080p (3840×2160 versus 1920×1080). At the same compression and format, a 4K export is roughly four times the size of a 1080p one.
• MOV (HEVC) uses a lower base bitrate than MP4 (H.264), about three-fifths of it, so at the same compression a MOV is roughly 60% of the MP4's size. The app describes MP4 as "Plays everywhere. Best default for sharing." and MOV as "smaller files at matching quality." See H.264 vs HEVC for the trade-offs.
• Studio at 4K is roughly eight times a 1080p Social Media export of the same video.

Audio adds little: AAC at 128 kb/s.

For a real figure, read the summary line in the Export sheet: "~size • duration • W×H (estimate ±30%)". To plan before you record, try the video file size calculator.

The raw recording needs space too. Before it starts, Screen Bolt checks that the output volume has room for 60 minutes at the estimated bitrate, so large captures need more free space.

When 1080p is the better choice

4K earns its file size for a launch video shown on a big screen, a course on a platform that serves 4K, or footage you'll crop later. Otherwise, 1080p is often the better export:

• People watch small. Slack embeds, Notion pages and help-center widgets are shown far smaller than 4K, so the extra pixels never reach anyone.
• Smaller files upload and load faster. A 1080p file is about a quarter the size of a 4K file.
• Your capture isn't 4K anyway. If it is under 2160 pixels tall, a 1080p export is real detail scaled down and still looks sharp, especially with zooms.
• GIFs. GIF export tops out at 960 pixels wide, so 4K doesn't matter there.

A good default for high-quality screen recording on a Mac: use the highest "looks like" resolution you can still read comfortably, record at 60 fps, and export 1080p MP4 at Social Media compression. Keep 4K or Original for the videos that need it. For per-platform settings, see best screen recording settings for YouTube, X and LinkedIn.

A note on webcams

The webcam is recorded to its own file. Max camera resolution in the Camera menu is 720p, 1080p (the default) or 4K. The camera overlay starts at 17% size, so 1080p is usually plenty. Consider 4K only if you use Fullscreen Moments, where the camera fills the whole canvas, and only if your camera supports it.

Compare the methods

If you just need a sharp raw file of the whole screen, the built-in toolbar is enough. Screen Bolt Pro makes more sense if you want to choose the frame rate, record a single window, export a fixed 4K or 1080p size and have your edits baked in.

If 4K isn't available or the file looks wrong

• The 4K tile is disabled. The recording is less than 2160 pixels tall. Export Original, or raise your display's "looks like" resolution (or make the window or area larger) and record again.
• Only 720p can be selected. You're using the free version, and the prompt says "Quality presets above 720p require a Screen Bolt license." Enter your key in Settings ▸ General ▸ License, or press ⇧⌘L (Command-Shift-L).
• Recording won't start: "Not enough free disk space to record safely." The app needs room for 60 minutes at your capture size. Free up space on the output volume and try again.
• "Recording finished with N dropped frame(s)… Likely cause: slow disk or thermal throttle." Switch to 30 FPS, record a window or area instead of a large display, close heavy apps and free disk space. See choppy screen recording fixes.
• The export plays at 30 fps. Frame rate was set to 30 when you recorded or exported. If you recorded at 60, set 60 FPS in Quick export and export again. If you recorded at 30, you need a new recording.
• The Original export is huge but not sharper. You probably recorded a standard-density monitor, where the 2× capture holds no extra detail. Export at 1080p, or record on a Retina display.

FAQ

Can a MacBook record 4K without an external display? Only if its scaled resolution looks like 1080 points tall or more. If not, the capture (for example 3024×1964) is still well above 1080p, so export Original or 1080p.

Does the free version of Screen Bolt record in 4K? It records at the same capture size as Pro, but free exports are limited to 720p and 3 minutes and are watermarked. The project keeps the full-resolution recording, so you can export it at 4K after activating a license.

Can I turn a 1080p recording into 4K? You can upscale it in a video editor, but that adds pixels without adding detail. Screen Bolt disables presets larger than the recording for that reason. Record at a higher "looks like" resolution instead.
