3. Video Grabber

Video Grabber is an all-in-one YouTube online HD video downloader, a web-based YouTube downloader that gives users the possibilities to grab videos from hot online video-sharing sites such as YouTube, Lynda, Twitch, LiveLeak, Vevo & TED. Another feature which catches my attention is that Video Grabber handpicks a series of hot videos and places them on its site, so you can watch, search, and download videos through this one-stop service even without heading to the YouTube. Apart from downloading, it also offers a function of converting videos from YouTube to the formats like MP4, MKV, AVI, MOV, WMV & formats compatible with devices such as Samsung, Huawei, iPad, iPhone, PSP & iPod touch etc. If you think these are all the functions Video Grabber has, then you are totally wrong. It’s also integrated with a screen recording function, which will spare you much trouble of installing another screen capture product, and you can also use this recording feature to record live streaming video on YouTube. What a great application I have to say.

  3. A built-in recording feature to record live YouTube videos like sports or games

Cons:

4. SaveFrom.net

The first time you use SaveFrom.net, you have to download a file named SFHlper which allows you to add an extension of Chrome, only in this way can you download videos freely. It’s a feature sounds a lot like Clip Converter Addon. Another bad impression of this application is the ads, just leave it alone. As for downloading, the most impressive function of this product is that it provides an easier & innovative way to download videos – adding letters. So: how can you save YouTube HD videos as MP4 online with this SaveFrom? The answer is dead easy.

For example, let’s say that you are playing a YouTube video, the video is quite intriguing, and you are eager to keep it on your devices. Then you install the plugin, and you will take notice of the URL on the address line. At this point, you just add “savefrom.net/” or “sfrom.net/” before the URL starts with “https”, or use short domain names like ”ssyoutube.com” to replace “youtube.com”. Now you just press the Enter key, and you will be redirected to the download page like magic. By now you just choose your downloading parameter, hit download button, then the video will be directly saved to your portable contrivances like computer, mobile phone or SD card without any other superfluous operation.
