How to record a product walkthrough on a Chromebook

You need to show students how a product or website works, but a written explanation is not enough. A short screen recording can show each click and result while you explain what to notice.

Use TooLab’s Screen Recorder to capture a browser tab, window, or screen on your Chromebook. You can include sound, your microphone, and your camera. Plan the walkthrough first, then make a brief test recording so you can check the picture and audio before teaching with it.

Record the walkthrough

1. Open the Screen Recorder on your Chromebook. Decide what students need to see, and close unrelated tabs, messages, and personal documents before you begin.
2. Choose whether to record a browser tab, a window, or the whole screen. A tab is a good choice for a web product because it keeps other open windows out of the recording. Use the browser’s sharing prompt to select the source and confirm sharing.
3. Choose the sound you need. Include the tab’s sound if the product plays audio, and use the microphone if you will explain the steps aloud. If you want your face on screen, enable the camera option and allow the browser to use it.
4. Make a short test clip. Explain one step, click through it at a calm pace, and stop the recording. Play it back to check that the text is readable, the pointer is easy to follow, and your voice is audible.
5. Record the full walkthrough in short, clear sections. When you finish, save the resulting video to your Chromebook, then open it from the Files app to check the saved copy before sharing it with students.

Choose what students should see

Record one browser tab

Choose a tab when the product runs in a website and you do not need to switch to another app. This keeps your other tabs and desktop out of view. If the lesson depends on a page’s sound, check that the browser sharing prompt includes audio for the selected tab.

Record a window or the whole screen

Choose a window if you need to show a desktop app. Choose the whole screen only when the walkthrough must move between windows or show a system setting. Before sharing the recording, watch it once to make sure no private notification or unrelated information appeared.

Include narration or a camera view

Narration helps students understand why a step matters, not just where to click. Keep your microphone close enough for a clear voice, and speak at a steady pace. A camera view can add a personal introduction, but it is optional. If students need to focus on small interface details, leaving the camera off gives the screen more space.

The video has a picture but no sound

The screen capture worked, but the audio source may not have been selected or shared. Tab audio and microphone audio are separate choices. Play the test clip and check which source is missing before recording again.

Fix common recording problems

1. Choose the right source. If students cannot see a menu or window you demonstrate, stop and select the window or full screen instead of a single tab. If you switch sources during a lesson, make a fresh test clip first.
2. Allow the browser to use the microphone or camera. When the browser asks for permission, allow access for the feature you want to use. If you blocked it earlier, open the site controls beside the address bar, change the microphone or camera permission, then reload the recorder. The recorder asks for permission before using either device.
3. Check Chromebook privacy controls. Open Settings › Privacy and security › Privacy controls and check whether microphone access is available and enabled on your Chromebook. The names or availability of controls can vary by ChromeOS version and device. If a school manages the Chromebook, an administrator may restrict recording or device access.
4. Check audio in the sharing prompt. When you select a tab, look for the option to share its audio if the walkthrough needs it. For narration, check that the correct microphone is selected in the recorder and speak during the test. A silent recording does not necessarily mean the microphone is broken.
5. Make the interface easier to read. Increase the page zoom before recording if labels look small. On a Chromebook, use Ctrl + + to zoom in and Ctrl + 0 to reset the page zoom. Move the pointer deliberately and pause after important changes so students have time to follow.
6. Update ChromeOS and restart the browser. If the screen picker does not appear or recording stops unexpectedly, close other recording or meeting tabs, restart Chrome, and check for ChromeOS updates in Settings › About ChromeOS. If this Chromebook is managed by a school, ask its administrator before changing restricted settings.

Check the video before sharing

Watch the saved video from beginning to end. Confirm that the opening explains the goal, each step is visible, and the final screen shows the result students should expect. Check the volume on the device you will use to teach, because a voice that sounds clear through a headset may be too quiet through laptop speakers.

Keep the recording short enough for students to find the part they need. If you made several takes, use the clearest one rather than sharing a long recording with pauses and repeated attempts. TooLab’s Screen Recorder runs in the browser, and recordings stay on your device. Nothing you record is uploaded by the recorder.
