凭借当今超快的互联网速度和尖端的桌面硬件，断断续续的YouTube视频应该已成为过去。可悲的是，事实并非如此。发生这种情况时，我们将向您展示如何修复YouTube。
YouTube(Does YouTube)在播放视频时会卡顿或卡顿吗？各种原因——例如不稳定的互联网连接、错误配置的质量设置和过时的视频驱动程序——通常会导致这种情况。继续阅读以了解如何在 PC 和Mac上修复断断续续的(Mac)YouTube视频。
检查您的互联网连接
首先(First)，检查您的互联网是否有问题。最好的方法是尝试使用替代的在线视频流服务，例如Vimeo或Netflix，或者您的Android或 iPhone上的YouTube应用程序。如果您继续遇到生涩或缓冲的视频，请尝试以下操作：
- 重启路由器。
- 重新启动您的 PC 或 Mac。
- 连接(Connect)到不同的Wi-Fi或以太网(Ethernet)连接。
如果问题仍然存在，请了解您可以采取哪些其他措施来修复速度较慢的 Wi-Fi(fix a slow Wi-Fi)或以太网连接(Ethernet connection)。
检查服务器端问题
断断续续的视频播放也可能是YouTube(YouTube)服务器端问题的结果。尽管Google没有提供专门的在线门户来检查这一点，但您始终可以使用第三方工具，例如DownDetector或IsItDownRightNow？确定 YouTube 是否经历了任何服务中断。
降低视频质量
尽管YouTube足够聪明，可以根据您的互联网连接和硬件速度自动调整视频质量，但这可能不会一直发生。它可能会卡在比您的互联网连接或计算机无法处理的分辨率更高的情况下。
尝试手动降低视频质量。在全屏模式下，选择媒体播放器窗格或屏幕左下角的齿轮形设置图标。(Settings)然后，指向质量(Quality)，并选择亚高清分辨率（360p 或 480p）。
如果这有帮助，请逐步提高，直到在视觉清晰度和性能之间找到良好的平衡。
更新您的网络浏览器
以下修复涉及更新您的网络浏览器，以解决YouTube依赖于视频播放的VP9编解码器的任何已知问题。
Web浏览器往往会自动更新，但最好还是手动检查以防万一。例如，您可以通过打开Chrome 菜单( Chrome menu)并选择帮助(Help )>关于 Google Chrome来强制更新(About Google Chrome)Chrome。
您(Are)使用的是Edge、Safari还是Firefox？了解(Learn)如何更新 PC(update any web browser on the PC)和Mac上的任何网络浏览器。
注意(Note)：YouTube 不再使用Adobe Flash Player在现代HTML5浏览器上播放视频。与(Contrary)您在线阅读的内容相反，您不需要安装、更新或使用任何Flash插件。此外，Flash 已死(Flash is dead)。
清除浏览数据
过时(Obsolete)的浏览数据是许多问题的常见原因，不仅是YouTube口吃，还有其他网站的一般问题。清除浏览器的缓存并检查是否有影响。
再次以Chrome为例，在新选项卡中输入chrome://settings/clearBrowserData并按Enter。然后，将时间范围(Time range)设置为所有时间( All time)，选择Cookies 和其他站点数据(Cookies and other site data )以及缓存的图像和文件(Cached images and files)类别，然后选择清除数据(Clear data)。
有关更多信息，请查看我们的 PC 和 Mac 浏览器清除缓存(clearing the cache in any browser for PC and Mac)指南。
仔细检查您的附加组件
浏览器(Browser)扩展是导致YouTube视频播放断断续续的另一个原因。尝试禁用任何活动的附加组件（特别是声称可以增强 YouTube 的内容拦截器或扩展程序(extensions that claim to enhance YouTube)）并检查是否能解决问题。然后，您可以在单独的选项卡中重新加载YouTube时一一重新激活它们，直到您隔离有问题的项目。
要启用和禁用附加组件(enable and disable add-ons)，您必须访问浏览器的扩展管理器(Extensions Manager)。例如，在Chrome中，只需打开(Chrome)Chrome 菜单(Chrome menu)（选择地址栏右侧的三个点）并选择更多工具(More Tools)>扩展程序(Extensions)。
禁用硬件加速
硬件加速(Hardware acceleration)是一把双刃剑。它使用您计算机的硬件来提高渲染性能，但它可能会对某些系统产生负面影响。因此，大多数浏览器（不包括Safari）都允许(Safari—allow)您禁用该功能。
在 Chrome 中，打开“设置”(Settings)窗格并转到“高级(Advanced)” > “系统(System)” 。然后，关闭使用时可用的(when available)硬件加速( Use hardware acceleration) 旁边的开关。您可以在其他基于 Chromium 的浏览器（例如Microsoft Edge和Opera ）上使用相同的方法。
在 Firefox 上，转到设置(Settings)>常规(General)>性能，然后取消选中(Performance)使用推荐的性能设置( Use recommended performance settings )和启用时使用硬件加速(Use hardware acceleration when enabled)旁边的框以禁用硬件加速。
如果这有帮助，您可以通过更新 PC 或Mac(Mac)上的视频驱动程序和系统软件来继续进行故障排除。
更新视频驱动程序
最新的显卡驱动程序可以帮助避免性能问题，尤其是在 PC 上。检查您的视频卡制造商的网站 — NVIDIA、AMD、Intel — 是否有任何更新并安装它们。或者，这里有一个更好的主意——使用驱动程序更新工具来自动更新(driver updater tool to auto-update all drivers)计算机上的所有驱动程序。
如果您使用Mac，将系统软件更新到最新版本也将更新图形驱动程序（下一个更多内容）。
更新系统软件
操作系统的潜在问题也可能导致视频播放问题。您可以通过安装最新的 Windows 或 macOS 更新来解决此问题。
在 Windows 10 和 11 中，打开“开始”菜单(Start menu )并选择“设置”(Settings) > “ Windows 更新”(Windows Update) > “检查更新(Check for updates)” > “下载并安装(Download and install)” 。此外，选择查看可选更新(View optional updates)并安装任何Microsoft 认证的(Microsoft-certified)硬件驱动器（如果有）。
在 Mac 上，打开Apple 菜单(Apple menu)并选择System Preferences。然后，选取“软件更新”(Software Update ) > “立即( Update Now)更新”以将 macOS 更新到其最新版本。
切换浏览器
如果YouTube的视频卡顿或播放不连贯的问题仍然存在，您可能需要切换浏览器作为最后的手段。YouTube在(YouTube)Chrome上效果最好，考虑到谷歌(Google)支持这两者，这不足为奇。
因此，如果您使用Safari或Firefox等浏览器，请尝试在Chrome上观看(Chrome)YouTube。如果问题出现在Chrome上，请尝试使用其他基于 Chromium 的 Web 浏览器(using a different Chromium-based web browser)，例如Edge或Opera。在您这样做之前，您可以随时尝试将浏览器恢复出厂设置。(factory resetting your browser)
How to Fix Choppy Videos on YouTube
With today’s blazing fast internet speeds and cutting-edgе deѕktop hardware, choppy YouTube vіdeos are sυpposed to be a thing оf the past. Sadly, that’s just not the case. We’ll show yоu what tо do to fіx YouTube when that happens.
Does YouTube freeze or stutter while playing videos? Various reasons—such as spotty internet connectivity, misconfigured quality settings, and outdated video drivers—often cause that. Read on to learn how to fix choppy YouTube videos on the PC and Mac.
Check Your Internet Connection
First up, check that there’s nothing wrong with your internet. The best way to do that is to try using an alternative online video streaming service such as Vimeo or Netflix, or the YouTube app on your Android or iPhone. If you continue to experience jerky or buffering videos, try the following:
- Restart the router.
- Restart your PC or Mac.
- Connect to a different Wi-Fi or Ethernet connection.
If the issue persists, learn what else you can do to fix a slow Wi-Fi or Ethernet connection.
Check for Server-Side Issues
Choppy video playback could also be the result of server-side issues with YouTube. Although Google doesn’t offer a dedicated online portal to check that, you can always use a third-party tool such as DownDetector or IsItDownRightNow? to determine if YouTube’s going through any service outages.
Lower the Video Quality
Although YouTube is smart enough to adjust video quality automatically depending on the speed of your internet connection and hardware, that may not happen all the time. It can get stuck at a higher resolution than your internet connection or computer just can’t handle.
Try lowering the video quality manually. Select the cog-shaped Settings icon on the lower-left corner of the media player pane or screen while in fullscreen mode. Then, point to Quality, and select a sub-HD resolution (360p or 480p).
If that helps, gradually work your way up until you find a good balance between visual clarity and performance.
Update Your Web Browser
The following fix involves updating your web browser to resolve any known issues with the VP9 codec that YouTube relies on for video playback.
Web browsers tend to update themselves automatically, but it’s always good to perform a manual check just in case. For example, you can force-update Chrome by opening the Chrome menu and selecting Help > About Google Chrome.
Are you using Edge, Safari, or Firefox? Learn how to update any web browser on the PC and Mac.
Note: YouTube no longer uses the Adobe Flash Player for video playback on modern HTML5 browsers. Contrary to what you may read online, you don’t need to install, update, or use any Flash plugins. Also, Flash is dead.
Clear the Browsing Data
Obsolete browsing data is a common reason for numerous issues, not just with YouTube stuttering but also problems with other sites in general. Clear your browser’s cache and check if that makes a difference.
Again, taking Chrome as an example, type chrome://settings/clearBrowserData into a new tab and press Enter. Then, set the Time range to All time, pick the Cookies and other site data and Cached images and files categories, and select Clear data.
For more information, check out our guide to clearing the cache in any browser for PC and Mac.
Double-Check Your Add-ons
Browser extensions are another reason that results in choppy YouTube video playback. Try disabling any active add-ons (specifically, content blockers or extensions that claim to enhance YouTube) and check if that resolves the issue. You can then reactivate them one by one while reloading YouTube in a separate tab until you isolate the problematic item.
To enable and disable add-ons, you must get to your browser’s Extensions Manager. In Chrome, for example, just open the Chrome menu (select three dots to the right of the address bar) and select More Tools > Extensions.
Disable Hardware Acceleration
Hardware acceleration is a double-edged sword. It uses your computer’s hardware to improve rendering performance, but it can negatively affect some systems. Therefore, most browsers—excluding Safari—allow you to disable the feature.
In Chrome, open the Settings pane and go to Advanced > System. Then, turn off the switch next to Use hardware acceleration when available. You can use the same approach on other Chromium-based browsers such as Microsoft Edge and Opera.
On Firefox, go to Settings > General > Performance and uncheck the boxes next to Use recommended performance settings and Use hardware acceleration when enabled to disable hardware acceleration.
If that helps, you can continue troubleshooting by updating the video drivers and the system software on your PC or Mac.
Update the Video Drivers
Up-to-date graphics card drivers can help avoid performance issues, especially on the PC. Check your video card manufacturer’s website—NVIDIA, AMD, Intel—for any updates and install them. Or, here’s an even better idea—use a driver updater tool to auto-update all drivers on your computer.
If you use a Mac, updating the system software to its latest version will also update the graphics drivers (more on that next).
Update the System Software
Underlying problems with the operating system can also cause video playback issues. You can fix that by installing the most recent Windows or macOS update.
In Windows 10 and 11, open the Start menu and select Settings > Windows Update > Check for updates > Download and install. Additionally, select View optional updates and install any Microsoft-certified hardware drives, if available.
On the Mac, open the Apple menu and select System Preferences. Then, choose Software Update > Update Now to update macOS to its latest version.
Switch Browsers
If YouTube’s video stuttering or choppy playback issues linger, you may want to switch browsers as a last resort. YouTube works best on Chrome, which shouldn’t come as a surprise considering that Google is behind both.
So, if you use a browser such as Safari or Firefox, try watching YouTube on Chrome. If the issue occurs on Chrome, try using a different Chromium-based web browser such as Edge or Opera. You could always try factory resetting your browser before you do that.
