I’m just posting this in case someday my source of information is lost. This is in regards to downloading videos off YouTube.

Step 1:
Go to YouTube video that you want. View the page source.

Step 2:
In the page source, search for “player2″

It’ll look something like:
player2.swf?video_id=(long string of numbers, letters, and symbols)”

Copy all content between = sign and ” mark.

Step 3:
Insert http://www.youtube.com/get_video?video_id= into URL
Insert copied content after = sign
Hit Enter
That should download the video as Get_Video with no extensions.

Step 4:
Go to downloaded file and rename it to whatever you want to and add .flv to the end as the file extension.

Step 5:
Download an FLV player. Plenty of them out there like VLC Media Player.

And that’s it. I’ve adopted this method for YouTube videos that I want to post on my site because I know how long my site will be around, but I sure as hell don’t know when a particular YouTube video will stay on their database.
