aiglas: Complete Guide to How To On Screen Recording

What Is Screen Recording and Why Bother?

Screen recording captures everything happening on your display as a video file. Simple as that. If you've ever needed to show a colleague how to use software, document a bug, or save a live webinar, you already know why learning how to on screen recording matters.

I spend half my working day on the road around East Belfast, but the other half involves sorting out delivery schedules, training new drivers on our routing app, and — honestly — recording my screen more than I ever expected. Quick 90-second walkthroughs save me repeating myself five times a week.

The UK's remote working figures back this up. According to GOV.UK workforce statistics, around 28% of UK workers operated in a hybrid model through 2025. Screen recordings aren't just for YouTubers anymore. They're a daily communication tool.

Built-In Tools for Screen Capture: Windows, Mac, and Chromebook

You don't need to download anything to start. Every major operating system ships with a screen capture tool already installed.

Windows 10 & 11: Xbox Game Bar

Press Win + G to open the Game Bar. Hit the record button or use Win + Alt + R to start immediately. Maximum recording length is 4 hours. Output format is MP4 at up to 1080p/60fps.

It's decent for quick captures. That said, it won't record your desktop or File Explorer — only application windows. Bit annoying if you need to show someone how to organise files.

Windows 11: Snipping Tool (2026 Update)

Microsoft added video capture to the Snipping Tool in late 2024. Press Win + Shift + S, select "Record," then draw your capture area. No time limit. No watermark. Brilliant for partial-screen recordings.

macOS: Screenshot Toolbar

Press Cmd + Shift + 5. Choose "Record Entire Screen" or "Record Selected Portion." Files save as MOV. Quality tops out at your display's native resolution — so on a Retina MacBook, that's up to 2560×1600.

Chromebook: Built-In Screen Capture

Press Ctrl + Shift + Overview key. Select your recording area. Files save as WEBM format to your Downloads folder. Maximum resolution matches your display (typically 1920×1080 on most Chromebooks).

Online Screen Recorders — No Install Needed

Browser-based tools let you record your screen without installing software. They're spot on for shared computers or locked-down work machines where you can't add programmes., a favourite among Britain’s tradespeople

The aiglas screen recorder runs entirely in your browser. No sign-up required for recordings under 5 minutes. You get options for full screen, specific window, or browser tab capture — plus simultaneous microphone and system audio recording.

So what's the catch with online tools? Most cap your recording length or resolution on free tiers. Some add watermarks. The aiglas tool doesn't watermark, which is why I've stuck with it for quick how-to videos I send to the team.

Worth the extra spend on a desktop app? Depends on your use case. If you're recording 30-minute training sessions daily, probably yes. For 2-3 minute explainers? An online recorder handles it perfectly.

Step-by-Step: How to On Screen Recording in Under 2 Minutes

Here's the fastest method I've found, using a browser-based approach that works on any operating system.

Step 1: Open Your Recording Tool

Handle to aiglas.co.uk/screen-recorder in Chrome, Edge, or Firefox. The interface loads in under 3 seconds on a standard broadband connection.

Step 2: Choose Your Capture Area

Select from three options:

• Entire Screen — captures everything, including taskbar and notifications
• Application Window — records a single programme window
• Browser Tab — captures only one tab (ideal for web app tutorials)

Step 3: Configure Audio

Toggle microphone on if you want voiceover narration. Enable system audio to capture sounds from the application you're recording. You can test your mic beforehand using the aiglas mic test tool — takes about 10 seconds and confirms your input levels are right.

Step 4: Hit Record

Click the red record button. A 3-second countdown gives you time to switch to the correct window. Your recording is now live.

Step 5: Stop and Save

Click the stop button in the floating toolbar (or press Ctrl + Shift + S on most tools). Your file downloads automatically as MP4 or WEBM. Typical file size: roughly 15-25 MB per minute at 1080p.

Getting Audio Right When You Record Your Screen

Bad audio ruins an otherwise perfect screen capture. I've learned this the hard way — sent a training video to six new starters and nobody could hear my instructions over the background hum from my laptop fan. Lesson learned, eventually., meeting British quality expectations

Microphone vs System Audio

Microphone audio captures your voice through an external or built-in mic. System audio captures sounds playing on your computer — notification pings, video playback, application sounds.

For tutorials, you typically want both. For recording a video call, system audio alone usually suffices. The aiglas call recorder handles this automatically if you're specifically capturing meetings or phone calls.

Quick Audio Checklist

• Test mic levels before recording (aim for -12dB to -6dB peak)
• Close unnecessary browser tabs — they can generate notification sounds
• Use a headset if you're in a noisy environment
• Record a 10-second test clip and play it back before your main recording

Honestly, a £25 USB headset from any high street electronics shop produces better audio than a £200 laptop's built-in microphone. The Which? headset reviews have solid recommendations if you're unsure what to buy.

Screen Recording Tools Compared: January 2026

I've tested these tools over the past 6 months. Here's how they stack up for everyday screen capture tasks.

My take? For most people learning how to on screen recording, a browser-based tool or the built-in OS option covers 90% of needs. OBS is powerful but has a steep learning curve — I spent a good 45 minutes configuring it the first time. Camtasia's brilliant if you need editing built in, but that price tag stings.

Tips From Someone Who's Done It Wrong (Multiple Times)

After recording probably 200+ screen captures over the past year, here's what I wish I'd known from day one.

Close Notifications Before Recording

Nothing worse than a WhatsApp message popping up mid-recording. On Windows, enable Focus Assist. On Mac, turn on Do Not Disturb. Takes 5 seconds and saves you re-recording.

Plan Your Click Path

Before hitting record, mentally walk through what you're going to show. Viewers lose patience after about 15 seconds of aimless cursor movement. My recordings dropped from an average of 4 minutes to 90 seconds once I started planning the sequence.

Use Keyboard Shortcuts

Keyboard shortcuts look cleaner on screen than hunting through menus with your mouse. They also speed up your recording by 30-40%. Write a sticky note with the 3-4 shortcuts you'll need and stick it on your monitor. (Yes, an actual sticky note. Old school works.)

Resolution Matters Less Than You Think

Recording at 1080p is fine for 95% of use cases. 4K files are 4x larger (roughly 80-100 MB per minute) and most viewers watch on phones or small laptop screens anyway. That said, if you're recording tiny text in a code editor, 4K does help. For general software walkthroughs? 1080p. Sorted., popular across England

File Management

Create a dedicated folder. Name files with the date and topic: 2026-01-15_routing-app-tutorial.mp4. You'll thank yourself in three months when you need to find that specific recording. I've got 47 files called "Screen Recording 2025-xx-xx" that I can't identify without opening each one.

The HSE guidance on display screen equipment is also worth a read if you're spending extended periods recording — proper monitor positioning and break schedules apply just as much during recording sessions as regular computer work.

Key Takeaways

• Every major OS has a free built-in screen recorder — Windows (Game Bar + Snipping Tool), macOS (Cmd+Shift+5), and Chromebook (Ctrl+Shift+Overview).
• Browser-based tools require zero installation and work on locked-down work computers where you can't install software.
• 1080p recording at 15-25 MB per minute is sufficient for 95% of tutorial and documentation use cases.
• Test your audio before every recording session — bad sound is the number one reason people stop watching screen captures.
• Learning how to on screen recording takes under 2 minutes with modern tools — the setup barrier has essentially disappeared in 2026.
• Name your files descriptively with dates to avoid the "47 unnamed recordings" problem that hits everyone eventually.
• Close notifications and plan your click path before recording to keep videos short, professional, and re-take-free.
