If you’re using Firefox as your browser, there are a wealth of addons available for the purpose. Personally I use NetVideoHunter. It suits the way I work. Other options are;
1-Click YouTube Video Download
There are plenty of others..
For Google Chrome, you could try:
- YouTube Downloader – 1.1
Opera has a number of widgets available for the same purpose, but I know nothing about them, like wise Internet Explorer, I haven’t used that in years…
Alternatively there is a really useful bookmarklet at Clipnabber.
If you’re a little command line oriented like myself, the handy tool youtube-dl I find quite practical.
youtube-dl -t "http://youtube.com/watch?v=quuxthing" mplayer "This Is What the title looks like but its just an example.flv"
youtube-dl will work even if you only give it the video code (usually at the end of the URL, after “v=”), like this:
youtube-dl -t zJOS0sV2a24
Allegedly supported on Mac/Unix/Win, but I can only speak for Linux.
JDownloader will really help. If you copy a YouTube link to the clipboard it will give you various options like,
- download MP3 files
- download Flash videos
- download MP4 files
- download in 320, 460, 720, etc.
Moreover, if you copy a YouTube playlist link, it will parse all videos and gives you option to download all the videos in the playlist.
Supports/has plugins for more than 200 other sites like (Hotfile, MediaFire, ifile.it, etc.)
You must give it a try, it will become your all in one download manager.
One more thing, it supports multithreaded downloading.
