QREATA / Features

Blur sensitive information in a screen recording on Mac

A customer’s email, an API key, a chat window in the corner: Qreata gives you three ways to keep them out of the video. Cover a rectangle in the editor after the take, pick an interface element before or during the take so the blur moves with it, or list the apps that should never appear at all.

The short answer

Qreata blurs part of a Mac screen recording in three ways. In the editor, the “Blur” tool covers a rectangle for a time range you set, at a strength of 4–80 or as a black “Solid fill”, and you can remove it later. “Blur · select elements”, set in the launcher before recording or from the recording pill during it, blurs up to 8 interface elements and follows each one as the page scrolls. “Never show these apps” keeps listed apps out of display and area recordings. Qreata costs $49 once, with a 7-day full trial.

Use blur in Qreata when

You know what must stay private and it sits in a predictable place.

A name, email, balance or key is visible for part of a take that is otherwise good.
A sidebar or account menu shows your client list for the whole video.
You scroll a page while recording and one field on it must stay hidden wherever it moves.
A messenger or mail app keeps appearing in full-screen recordings.

It won’t help when

You need the software to find the data for you, or to chase it after the take.

You want sensitive data detected automatically. Qreata doesn’t detect it; you mark every area yourself.
The data moves and the take is already recorded. Editor regions are fixed rectangles that do not track movement.
You want a pixelated mosaic. The modes are blur and a black fill.
The video was recorded in another app. Qreata doesn’t import video files.

Three ways to hide sensitive information in a Mac screen recording

The three tools work at different moments, and the moment decides what is still possible. Blur added in the editor sits on top of the recording and can be changed or removed. Blur added while recording is saved into the picture for good. An app on the “Never show these apps” list is never captured in the first place.

Pick by asking whether the thing you are hiding moves. A fixed header, sidebar or dialog is a job for the editor. A field on a page you will scroll is a job for element blur during the take.

How to blur part of a screen recording in the editor

Say you recorded a 6-minute walkthrough of a billing dashboard. From 1:40 to 2:15 the page header shows a real customer’s email, and from 4:02 to 4:10 a settings dialog shows an API key. Neither moves on screen while it is visible, so both can be covered after the take.

Use “Blur” when the viewer should still see that something is there, such as a table with its rows smeared. Use “Solid fill” for anything that must be unreadable beyond doubt: a key, a password, a card number. A low blur strength can leave large text legible, so judge it at full-screen playback, not in the small preview.

Open the recording in the editor and choose the “Blur” tool.
Click “Add region” and drag a rectangle on the preview over the email in the header. Make it a little wider than the text, so a longer address on another frame is still covered.
A new region takes the time range of the segment under the playhead. On the Blur lane of the timeline, set it to 1:40–2:15. Start it a moment before the email appears and end it after it is gone.
Choose the mode. “Blur” has a strength from 4 to 80 and starts at 24; “Solid fill” paints the rectangle black. For the email, a strong blur is enough.
Click “Add region” again for the API key. You can add any number of regions, each with its own time range. Drag over the key in the dialog, set the range to 4:02–4:10 and choose “Solid fill”.
Play both ranges from two seconds before to two seconds after, at full screen. Pause on the first and last frame of each and check that nothing is readable at the edges.
Export the MP4. The regions stay in the project: drag one to move it, pull its corner handles to resize it, or remove it, and export again.

How to blur an element while recording so it follows the scroll

An editor region stays where you drew it. If you scroll a customer list, the row you covered slides out from under the rectangle. For content that moves, blur the interface element itself, before or during the take: Qreata attaches the blur to that element and keeps it there through scrolling and window moves.

This blur is baked in. It is saved into the recording and can’t be removed afterwards, so record a 20-second test on the same page before the real take.

For something that is not an interface element, such as part of an image or a video frame, the recording pill also has “Tools: blur and draw” with a live “Blur”: drag a fixed rectangle over the area, with no Accessibility permission needed. On your screen it shows as a grey dashed area, and the blur is only in the video. It is saved into the recording as well.

Give Qreata the macOS Accessibility permission in System Settings > Privacy & Security > Accessibility. Element blur doesn’t work without it.
In the launcher, choose the display, window, application or area you need. Element blur works in screen recordings and is not available in the camera-only “Just me” mode.
Choose “Blur · select elements” in the launcher, before you start. Move the pointer over the interface and click the elements to hide, for example the “Email” column and the account name in the sidebar.
Pick up to 8 elements. If you need a ninth, cover the rest with an editor region or a solid fill after the take.
Start recording and scroll as usual. The blur stays on each element as it moves.
If something sensitive turns up mid-take, click the “Blur” button on the recording pill. The recording pauses while you pick and resumes when you are done.
Watch the take once before you edit. If an element was missed for a few frames, add an editor region over that range.

Keep an app out of every recording with “Never show these apps”

Some things should not be in any video: a messenger, a mail client, a password manager. Open Settings, go to “Recording privacy” and add those apps under “Never show these apps”. In display and area recordings they are left out of the picture even when their windows are open on screen. Qreata’s own windows are always hidden, so the recording controls never appear in your video.

The list hides the apps’ windows. It does not hide notification banners: a banner that slides in from a chat app during a full-screen take is recorded. Before recording Qreata only reminds you to turn on a Focus mode, so turn one on. The list itself is set once and applies to every display and area recording after that.

Add the apps before you record. The list affects what is captured, not recordings you already have.
It applies to display and area recordings, where everything on screen would otherwise be in frame.
It hides whole apps. To hide one field inside an app you are demonstrating, use element blur or an editor region.

What Qreata’s blur can’t do

Nothing is detected for you. Qreata does not scan the screen for emails, keys or card numbers, so a field you didn’t mark stays visible. Watch the whole video before you send it.

Editor regions are fixed rectangles: they do not track scrolling or moving content, and there is no pixelate mode, only blur and a black fill. Element blur is limited to 8 elements, needs the Accessibility permission, can’t be removed once recorded, and depends on the app you are recording: some apps do not expose their interface elements, and in those you can’t pick anything.

Qreata blurs only its own recordings. It doesn’t import MP4 or MOV files, so a video you already made elsewhere has to be blurred in the tool it came from. The app runs on Apple Silicon Macs with macOS 14 or later.

Can you blur a screen recording with QuickTime Player?

No. The recorder built into macOS (Shift-Command-5) saves a .mov, and Apple’s list of QuickTime Player editing features is trim, split into clips, rearrange, rotate or flip, add a clip, and remove audio or video. Blur and redaction are not on it. On the free route the protection is preparation: record one window instead of the display, log in before you press Record, and use test records. If the data still got into the take, your options are to split the movie and remove that part, or to record again.

A 10-minute test in the Qreata trial: record 2 minutes of a page with a table, scroll it, and stop. Add one editor region over a fixed header with “Solid fill”, then record the same page again with “Blur · select elements” on one column. Compare the two exports at full screen. The trial runs 7 days with every feature and recording needs no account; the license is $49 once for 3 Macs, with no subscription.

Questions worth asking

How do I blur part of a screen recording on Mac?

In Qreata, open the recording in the editor, choose “Blur”, click “Add region”, drag a rectangle over the area and set its time range on the Blur lane. Pick “Blur” with a strength of 4–80 or a black “Solid fill”. QuickTime Player has no blur.

Can the blur follow something that moves or scrolls?

Yes, if you set it before or during recording. “Blur · select elements” attaches the blur to an interface element and follows it through scrolling and window moves, for up to 8 elements. Regions added in the editor are fixed rectangles and do not track movement.

Can I remove the blur later?

Yes for editor regions: they are non-destructive and can be changed or deleted before any export. No for element blur picked in the launcher or during recording: it is saved into the recording and can’t be removed.

Does Qreata detect passwords or personal data automatically?

No. There is no automatic detection of sensitive data. You mark each area or element yourself, so review the whole video before sharing it.

Can I blur a video I recorded with another app?

No. Qreata doesn’t import video files; blur works on recordings made in Qreata. For an existing file, use the editor it was made in.

Is blur a paid add-on?

No. Blur regions, element blur and “Never show these apps” are part of the app. The Personal license is $49 once for 3 Macs, and the 7-day trial includes every feature.
