谷歌将屏幕录制工具集成(integrated a screen recording tool)到Chrome OS 89中，主要是为了促进虚拟学习。如果您在Chromebook上进行大量在线课程(online classes)，或者在线教授学生，该工具可让您记录课程、报告和演示文稿以供参考。
但是，屏幕录制不仅限于学者；还有其他有趣的用例。您还可以录制YouTube视频、体育广播、游戏和其他娱乐内容或活动。继续下一部分，了解如何在Chromebook上进行屏幕录制。
如何录制 Chromebook 的屏幕(Screen)
按住Control + Shift + Overview 模式(Overview mode)（或Show windows 键）以启动Chrome OS截图工具。
如果您的Chromebook处于平板电脑模式，请打开状态(Status)区域并选择屏幕截图(Screen capture)。
截图工具将在屏幕底部弹出，就在Shelf的正上方。点击摄像机图标以导航到屏幕录制(Screen Record)菜单。
截图工具默认会预选“录制部分屏幕”模式。在此模式下，使用加号十字准线图标选择要录制的屏幕区域。
这非常适合录制在网站（如YouTube）上播放的视频，而无需录制整个网页。
注意：(Note:)您不能在录制过程中移动所选区域。要录制屏幕的另一部分，请取消正在进行的录制并绘制新的录制区域。
“记录(Record)窗口”选项可让您记录特定应用程序或窗口的内容。如果您在Chromebook 上以分屏模式(split-screen mode on your Chromebook)使用两个应用程序，此选项可让您在不关闭另一个应用程序的情况下记录一个应用程序的内容。
当您选择“录制(Record)窗口”选项时，您的光标将变为摄像机图标。使用触摸板移动图标并单击要录制的窗口上的任意位置。
最后，还有“录制(Record)全屏”选项。” 单击(” Click)虚线方形图标并单击屏幕上的任意位置以记录整个显示。
当您选择首选录制选项时，截图工具将在录制前在屏幕、选定区域或窗口上显示 3 秒倒计时。屏幕录像机将捕捉屏幕上的所有视觉元素，包括光标。但是，您应该注意，屏幕录像机默认情况下不会捕获音频。
您需要手动启用 Chromebook 的麦克风才能录制屏幕音频。按照下一节中的步骤了解它是如何完成的。
如何在没有音频的情况下录制 Chromebook 屏幕(Record Chromebook Screen Without Audio)
在你点击录制按钮之前，点击截图工具上的齿轮图标并打开录制麦克风(Record microphone)。
截图工具将保存设置，因此您不必在后续录音中手动启用麦克风。要在没有音频的情况下录制，请重复上述步骤并关闭录制麦克风(Record microphone)选项。
在启用麦克风的情况下录制屏幕将从Chromebook上播放的媒体中捕获音频。麦克风还会从环境中拾取背景声音。因此，如果您在Chromebook上使用音频进行屏幕录制，请确保在环境噪音最小的安静房间内进行。
更好的是，使用外部降噪麦克风(noise-canceling microphone)（如果有的话）。这可能有助于滤除背景噪音并最终提高录音的音质。
如何在Chromebook上停止(Chromebook)屏幕(Screen)录制
当屏幕录制开始时，您应该会在状态(Status)区域（屏幕的右下角）附近看到一个红色的停止图标。单击该图标将立即停止录制并保存文件。
您还将在状态区(Status Area)收到通知。单击(Click) “在文件夹中显示”以在“(Show in folder)文件”(Files)应用中查看录制内容。Chrome 操作系统(Chrome OS)会将屏幕截图和屏幕录像保存在“下载(Downloads)”文件夹中。
(Troubleshoot Screen Recording Problems)排查Chromebook(Chromebook)上的屏幕录制问题
在Chromebook(Chromebook)上进行屏幕录制时可能会遇到某些问题或困难。在本节中，我们将介绍其中一些问题的潜在解决方案。
Chromebook 不保存屏幕截图或屏幕录像？(Chromebook Not Saving Screenshots or Screen Recordings?)
如前所述，Chrome OS默认将屏幕截图和屏幕录像保存到Downloads文件夹。如果您在“下载(Downloads)”文件夹中找不到您的录音，则您的Chromebook可能存储空间不足。
前往“设置”(Settings) > “设备(Device)” > “存储管理(Storage management)”查看设备的存储状态。
释放(Free)一些空间，尝试再次录制屏幕，并检查视频是否已保存到您的设备。
Chromebook 不录制音频？(Chromebook Not Recording Audio?)
您启用了“录制(Record)麦克风”选项，但您的录音没有音频。可能是什么问题呢？
好吧，如果您的 Chromebook 的麦克风已静音，则截图工具可能无法捕获音频。在录制之前，请确保检查Chrome 操作系统(Chrome OS)的音频设置并确认允许音频输入。
打开状态区域并单击音量滑块旁边的箭头图标。(arrow icon)
在输入部分，向右移动麦克风（内部）(Microphone (Internal))滑块以增加 Chromebook 内置麦克风的音量。
如果您的Chromebook连接了外部音频设备，您也可以在此部分中找到该设备的麦克风滑块。如果增加音频输入音量后问题仍然存在，请重新启动Chromebook 并重(Chromebook)试。
找不到录屏工具？(Can’t Find the Screen Recording Tool?)
我们在本文的介绍中提到，谷歌(Google)将屏幕录制工具集成到Chrome OS 89中。如果您从状态区域(Status Area)或通过键盘快捷键访问屏幕录制工具，请确保您的 Chromebook 运行的是最新的Chrome 操作系统(Chrome OS)版本。
转到设置(Settings)>关于 Chrome 操作系统(About Chrome OS)，然后单击检查更新(Check for updates)。如果页面上有待处理的更新，请重新启动您的设备。
更新您的 Chromebook 还可以解决导致屏幕录制工具出现故障的其他问题。
并非所有Chromebook 应用程序都支持屏幕(Chromebook Apps Support Screen)录制
使用包含受保护内容的应用程序时，您无法录制屏幕。例如，尝试在Netflix或Amazon Prime Video应用上录制电影。您将在通知面板中收到“无法捕获内容”错误消息。
有趣的是，我们能够通过网络浏览器录制Netflix 。请注意，我们不建议这样做，因为未经许可在Netflix或其他地方录制或复制受版权保护的内容是完全违法的。在您的设备上录制内容之前，请确认您被允许这样做。
How to Screen Record on a Chromebook
Google integrated a screen recording tool into Chrome OS 89 primarily to foster virtual learning. If you take a lot of online classes on your Chromebook, or you teach students online, the tool lets you record lessons, reports, and presentations for reference purposes.
However, screen recording isn’t limited to academics only; there are other interesting use cases. You can also record YouTube videos, sports broadcasts, games, and other entertainment content or activities. Proceed to the next section to learn how to screen record on a Chromebook.
How to Record Your Chromebook’s Screen
Press and hold Control + Shift + Overview mode (or Show windows key) to launch the Chrome OS snipping tool.
If your Chromebook is in tablet mode, open the Status area and select Screen capture.
The snipping tool will pop up at the bottom of your screen, just right above the Shelf. Tap the camcorder icon to navigate to the Screen Record menu.
The snipping tool will preselect the “Record Partial Screen” mode by default. In this mode, use the plus-shaped crosshair icon to select an area of the screen you want to record.
This is perfect for recording a video playing on a website (like YouTube) without having to record the entire web page.
Note: You cannot move the selected area during recording. To record another portion of the screen, cancel the ongoing recording and map out a new recording area.
The “Record window” option lets you record the content of a particular app or window. If you’re using two apps in split-screen mode on your Chromebook, this option lets you record the content of one app without closing the other.
When you select the “Record window” option, your cursor changes to a camcorder icon. Use the touchpad to move the icon and click anywhere on the window you want to record.
Lastly, there’s the option to “Record full screen.” Click the dashed-square icon and click anywhere on the screen to take a recording of the entire display.
When you choose your preferred recording option, the snipping tool will display a 3-second countdown on the screen, selected area, or window before it records. The screen recorder will capture all the visual elements on the screen, including the cursor. However, you should note that the screen recorder doesn’t capture audio by default.
You’ll need to manually enable your Chromebook’s microphone to record your screen with audio. Follow the steps in the next section to learn how it’s done.
How to Record Chromebook Screen Without Audio
Before you hit the record button, click the gear icon on the snipping tool and toggle on the Record microphone.
The snipping tool will save the settings, so you don’t have to manually enable the microphone on subsequent recordings. To record without audio, repeat the steps above and toggle off the Record microphone option.
Recording your screen with the microphone enabled will capture audio from the media playing on your Chromebook. The microphone will also pick up background sound from the environment. Therefore, if you’re screen recording with audio on your Chromebook, make sure to do so in a quiet room with minimal ambient noise.
Better yet, use an external noise-canceling microphone, if you have one. That may help filter out background noise and ultimately enhance the sound quality of the recording.
How to Stop Screen Recording on Chromebook
When the screen recording commences, you should see a red-colored stop icon close to the Status area—the bottom-right corner of the screen. Clicking the icon will immediately stop the recording and save the file.
You’ll also get a notification in the Status Area. Click Show in folder to view the recording in the Files app. Chrome OS saves screenshots and screen recordings in the Downloads folder.
Troubleshoot Screen Recording Problems on Chromebook
It’s possible to run into certain problems or difficulties while screen recording on Chromebook. In this section, we cover potential solutions to some of these issues.
Chromebook Not Saving Screenshots or Screen Recordings?
As mentioned earlier, Chrome OS saves screenshots and screen recordings to the Downloads folder by default. If you don’t find your recordings in the Downloads folder, your Chromebook could be low on storage space.
Go to Settings > Device > Storage management to check your device’s storage status.
Free up some space, try recording the screen again, and check if the video is saved to your device.
Chromebook Not Recording Audio?
You enabled the “Record microphone” option but your recordings don’t have audio. What could be the problem?
Well, the snipping tool may fail to capture audio if your Chromebook’s microphone is muted. Before you record, make sure you check the Chrome OS audio settings and confirm that audio input is allowed.
Open the Status Area and click the arrow icon next to the volume slider.
In the Input section, move the Microphone (Internal) slider to the right to increase the volume of your Chromebook’s built-in microphone.
If there’s an external audio device connected to your Chromebook, you’ll find the device’s microphone slider in this section, too. Should the problem persist after increasing audio input volume, restart your Chromebook and try again.
Can’t Find the Screen Recording Tool?
We mentioned in the intro of this article that Google integrated the screen recording tool into Chrome OS 89. If you access the screen recording tool from the Status Area or via the keyboard shortcut, make sure your Chromebook is running the latest Chrome OS version.
Go to Settings > About Chrome OS and click Check for updates. Restart your device if there’s a pending update on the page.
Updating your Chromebook could also fix other issues causing the screen recording tool to malfunction.
Not All Chromebook Apps Support Screen Recording
You can’t record your screen when using apps with protected content. For example, try recording a movie on the Netflix or Amazon Prime Video app. You’ll get a “Can’t capture content” error message in the notification panel.
Interestingly, we were able to record Netflix through a web browser. Note that we do not recommend doing this because it’s outright illegal to record or reproduce copyrighted content—either on Netflix or elsewhere—without permission. Before you record content on your device, confirm that you’re allowed to do so.
