There are three easy ways by which we can download YouTube video or rather videos from most of the websites:
1. Installing Browser Extension or Addon to download YouTube videos
Whatever browser you use has an extension or addon to download YouTube videos. I have thoroughly used Mozilla Firefox so I only know of the extension which works like a charm. I will be researching more about other browsers and adding to this articles soon. The Mozilla Firefox addon which helps to download YouTube videos is Video Download Helper. They support video downloading for many video websites and you can check it out.
2. Using Real Player for downloading YouTube videos
When you install the Real Player it gives you an option to enable or disable video downloads using real player. Just keep a check of this option while installing real player and when ever you will be watching a video, you will get a prompt to download the video using real player. The options pops up for a fixed time frame like five to ten seconds as per your settings and you just have to click on it to start downloading videos.
3. IDM(Internet Download Manager) can download youtube videos for you
IDM(Internet Download Manager) has many options and so it allows you to download various things like download all files from a webpage, download complete webpage, download audio and also download video in available different resolutions. When you click on the download video option it gives you a list of all available resolutions of that particular YouTube video. You only have to smart choosing the resolution of the video and click it. Once you click on your choice IDM(Internet Download Manager) starts downloading.
I have gone through other methods of downloading YouTube videos as well over the internet but I found most of them to be either fuzzy or the softwares involved seems suspected. So it is totally your choice how to download YouTube videos using which method. You might be able to find some YouTube downloader softwares which are not easy to use and also don’t work accurately as they most of the times corrupt the downloaded video file.
