当您看到下载按钮时，下载视频很容易。不幸的是，大多数视频共享网站显然不允许下载，通常是为了保护版权或因为下载视频的需求不大。但是，即使没有下载按钮，您也可以使用一些工具和技巧来下载视频。(download videos)
也许您想下载(download a video)在新闻网站上找到的视频，或者将YouTube视频保存到您的计算机上？如果您正在在线观看免费电影(free movie online)并希望将其保存以供以后在飞机上观看，则需要下载该视频。
无论(Regardless)您这样做的原因是什么，通常都可以从 Internet 下载视频，但并不总是那么容易。您可以尝试使用视频下载器（这些是您最好的选择），也可以使用浏览器技巧来显示隐藏的下载链接。
重要提示(Important)：请注意您从中下载视频的网站，以及您可能违反的任何版权法。很多视频都是非法下载的，因为所有者没有授予您这样做的权限。
使用下载器工具下载视频(Download a Video With a Downloader Tool)
当没有明确的下载按钮时，从网站下载视频的最简单方法是使用视频下载工具。这些是特制的程序或网络应用程序，用于从网页中查找和提取视频。
Catch.tube是目前最好的之一。它完全免费，可在Twitter(Twitter)、CNN、Tumblr、YouTube、Facebook等流行网站上使用。要使用这个免费的视频下载器，只需访问网站并粘贴包含视频 的URL 。
您可以尝试的其他一些视频下载器包括Catchvideo.net、Savethevideo.com、RipSave和 Chrome 扩展Video Downloader。
破解您的浏览器以下载视频(Hack Your Browser To Download a Video)
每个网页都由您看不到的代码组成，除非您在幕后凝视，而且您观看的任何视频都是从特定来源流式传输的。如果您可以从代码中找到源链接，则可能可以访问下载链接。
一个明显的例子就是YouTube视频。从YouTube(YouTube)下载视频是一个流行的请求，并且有很多工具可以做到这一点（很多都是收费的），所以您可能会惊讶地发现，您可以从YouTube下载任何视频，而无需浏览器破解。您还可以一次下载整个 YouTube 播放列表(download entire YouTube playlists)。
桌面网络浏览器加载YouTube视频的方式与移动设备不同，因此这里的想法是告诉您的桌面浏览器请求YouTube视频，就像您在移动设备上一样。一旦您的浏览器加载该页面，就会看到一个唯一的下载链接，但前提是您必须找到该页面的源代码。
- 打开 Firefox 并转到about:config。将其视为URL，因此将其输入到浏览器顶部的导航区域。
- 右键单击(Right-click)空白区域并转到New > String。
- 将其命名为general.useragent.override，然后将这段代码放在那里：
Mozilla/5.0 (iPhone; CPU iPhone OS 8_3 like Mac OS X) AppleWebKit/600.1.4 (KHTML, like Gecko) FxiOS/1.0 Mobile/12F69 Safari/600.1.4
- 打开一个新标签并找到您要下载的YouTube视频。(YouTube)
- 启动视频并让它播放几秒钟。如果有广告，请先完成。
- 右键单击视频并选择检查元素(Inspect Element)。
- 在打开的新窗口中，找到<div id=”player”并单击其左侧的箭头将其展开，然后对其下方的<div id=”movie_player”和<div class=”html5-video-container”。
- 下面是src=”之后的长 URL 。双击它以查看完整的URL，右键单击它，然后选择Copy。
- 在Firefox(Firefox) （或任何浏览器）中打开一个新选项卡并将其输入到导航栏中。
- 右键单击(Right-click)该选项卡中的视频并选择Save Video As。
- 将videoplayback.mp4(videoplayback.mp4)下载到您的计算机以保存YouTube视频。如果需要，您可以重命名它。
- 返回到带有用户代理(user agent)设置的选项卡，右键单击您创建的新字符串，然后选择重置(Reset)以将 Firefox 返回到桌面模式。
这是另一个CNN天气视频在表面上没有下载链接的示例，但是如果您将Firefox设置为移动模式并刷新页面，源代码会显示一个简单的MP4下载链接。
这种下载视频的确切(exact)技术不适用于其他网站上的每个视频，因为某些视频流服务没有其页面的移动版本，但类似的方法可能会起作用。
如果检查视频页面没有显示下载链接，请尝试像我们上面所做的那样更改浏览器的用户代理(changing the browser’s user agent)，然后再试一次。使用其他浏览器（如Chrome(Chrome)或Edge ）可能也很幸运。
How To Download a Video From Any Website
Downloading videoѕ is easy when you see a download button. Unfortunatеly, most video sharing sites obviously don’t allow downloadѕ, usually to protect сopyrights or because there’s not a large demand to download their vіdeos. But there are tools and triсks yoυ can use to download videos even when there isn’t a download button.
Maybe you want to download a video you found on a news site, or save a YouTube video to your computer? If you’re watching a free movie online and you want to save it to watch later on an airplane, you’ll want to download the video.
Regardless of your reason in doing so, downloading videos from the internet is usually possible, just not always easy. There are video downloaders you can try (these are your best bet) but also browser tricks to reveal hidden download links.
Important: Be mindful of the website you’re downloading the video from, as well as any copyright laws you might be breaking. Lots of videos aren’t legal to download because the owner hasn’t given you permission to do so.
Download a Video With a Downloader Tool
The easiest way to download a video from a website when there isn’t a clear download button is to use a video downloader tool. These are specially made programs or web apps that look for and extract videos from webpages.
Catch.tube is one of the best ones out there. It’s totally free and works on popular websites like Twitter, CNN, Tumblr, YouTube, Facebook, and others. To use this free video downloader, just visit the website and paste the URL that contains the video.
Some other video downloaders you can try include Catchvideo.net, Savethevideo.com, RipSave, and the Chrome extension Video Downloader.
Hack Your Browser To Download a Video
Every webpage is made up of code that you don’t see unless you peer behind the scenes, and any video you watch is being streamed from a particular source. If you can find the source link from within the code, you might be able to reach a download link.
One clear example of where this works is with YouTube videos. Downloading videos from YouTube is a popular request and there are lots of tools that can do it (many that charge), so you might be surprised to learn that you can download any video from YouTube with nothing more than a browser hack. You can also download entire YouTube playlists at once.
A desktop web browser loads YouTube videos differently than a mobile one, so the idea here is to tell your desktop browser to request the YouTube video as if you were on a mobile device. Once your browser loads the page, a unique download link is visible, but only if you uncover the source code of the page.
- Open Firefox and go to about:config. Treat that like a URL, so enter it into the navigation area at the top of the browser.
- Right-click in an empty space and go to New > String.
- Name it general.useragent.override and then put this code there:
Mozilla/5.0 (iPhone; CPU iPhone OS 8_3 like Mac OS X) AppleWebKit/600.1.4 (KHTML, like Gecko) FxiOS/1.0 Mobile/12F69 Safari/600.1.4
- Open a new tab and find the YouTube video you want to download.
- Start the video and let it play for a few seconds. If there’s an ad, let that finish first.
- Right-click the video and choose Inspect Element.
- In the new window that opens, find <div id=”player” and click the arrow to its left to expand it, and then do the same for <div id=”movie_player” below it, and <div class=”html5-video-container” below that.
- Below that is a long URL following src=”. Double-click that to see the full URL, right-click it, and then choose Copy.
- Open a new tab in Firefox (or any browser) and enter that into the navigation bar.
- Right-click the video in that tab and choose Save Video As.
- Download videoplayback.mp4 to your computer to save the YouTube video. You can rename it if you want.
- Return to the tab with the user agent setting, right-click the new string you made, and select Reset to return Firefox to desktop mode.
Here’s another example where a CNN weather video has no download link on the surface, but if you turn Firefox into mobile mode and refresh the page, the source shows a simple MP4 download link.
This exact technique to download a video won’t work for every video on other websites become some video streaming services don’t have mobile versions of their pages, but a similar method might work.
If inspecting the video page doesn’t show a download link, try changing the browser’s user agent like we did above, and then give it another shot. You might also have luck using a different browser like Chrome or Edge.
