There are many friends asked me how to download videos from Google. At first I thought it's a difficult problem. I tried using Google Video and I found that I can download Google video with a download link provided by Google. The file I'll receive has the .gvp format. This file format can be played with Google Video Player.
But what will we do if we want to download the original video file with the .avi format or .wmv ..? The answer is using bookmarklet or JavaScript. If you want to save the original video file format without downloading Google's player, you can use a bookmarklet (JavaScript code). Make sure the link toolbar is visible in your browser. You can enable it if you go to View/Toolbars in your browser and check Bookmarks Toolbar in Firefox, Links in Internet Explorer or Personal Bar in Opera. Then drag and drop the bookmarklet:
At this time your toolbar will look like this :
Next time when you enjoy a video you like on Google Video, just click on the bookmarklet and save the video. Enjoy your videos!
