How to save YouTube and other Internet videos on your Mac computer
To save videos from websites such as YouTube and Google to your hard drive:

1. From a site such as YouTube.com, go to the video you want to save.

2. Copy the URL from that web page (for example: http://www.youtube.com/watch?v=-zFI35TVXao)

3. Go to http://keepvid.com

4. Paste the URL you copied in step 2 into the text box at the top of http://keepvid.com and click the Submit button.

5. Click on ›› Download Link ‹‹ when it appears below the text box. A file named something like get_video-1 will be copied to your computer.

6. Using Finder, rename the file so that it has the extension .flv (for example: get_video-1.flv) to indicate that this is a Flash Video file.

7. If you don't already have it, download a program called iSquint to your computer by going to http://www.isquint.org and clicking Download iSquint

8. Run iSquint and drag the get_video-1.flv (or whatever it's called) file from Finder into the central area in iSquint.

9. Click the Start button in the lower right corner of iSquint. If you keep the default settings, an MPEG-4 file will be created called get_video-1.mp4 (for example) that can be viewed in QuickTime or placed on the timeline of a video editing program such as Final Cut Pro.
