How To Save Flash Videos From YouTube

Okay so I thought I re-posted this article awhile back but when I looked through the blog archives I couldn't find it... so I'm posting it now.

The easiest way to save videos out of YouTube is by using the site KeepVid. It allows you to just plunk in the URL of of the video you are trying to acquire and then save it as a .flv file. You will need a .flv player to play it though:

The article:
"Every video posted in YouTube has its own video identification code.

The eleven digits of both upper and lower cased alpha-numeric video identification code is used to watch videos via YouTube’s website or embed them into other websites.

To download the videos via KeepVid or similar sites, the eleven digit video identification code is still useful, but in case of KeepVid crashes, user has to “kick it old school style” by reading YouTube video’s page source.

Using the F-16 Crash video (http://youtube.com/watch?v=b4Knsa7kBPE) as an example, here is how to save videos from YouTube “old school style”.

In Firefox browser, open “View Page Source” and do a text search for

player2.swf?video_id=

For this example video, its public video identification code is b4Knsa7kBPE, but the internal prolonged video identification code is

b4Knsa7kBPE&l=48&t=OEgsToPDskI3D6CVWsTxEa4Bzc
THKXc7&s=E04B5F8107785BA4:8A51374783A7BCE6

Keep in mind that the code between “&t=” and “&s=” may be session-sensitive and changed every time the video is accessed.

To save the video, the URL path format is

http://www.youtube.com/get_video?
video_id=prolonged_video_identification_code

By paste the above URL into browser would not download the video. The best way is to paste it into an email and send it to oneself.

The default file extension assigned by email clients (Gmail, Thunderbird, Outlook) when saving the video is html (hypertext markup language), change it to flv (flash video).

Media players like VLC can play flv files stand alone. To convert flv video to other formats like Audio Video Interlaced (.avi), Quicktime (.mov) or Windows Media (.wmv), use CinemaForge.

Update1: Keepvid.com can direct download videos from Google Video, YouTube, IFilm, Putfile and various other sites.

Update2: How to save videos from Comedy Central's website.

Update3: April 30, 2006 - Javi Moya has created an extension called VideoDownloader 1.0 for Firefox which would download embedded videos and media files directly from Youtube, Google, Metacafe, iFilm, and other 60+ video sites. (more)"
