Some time ago, I wrote a post on how to download flash video from any website using Firefox and Firebug. Since then Google Chrome has become my browser of choice, and it has a great debugger built into it, which makes it even easier. In this tutorial, I’ll show you how to download video from YouTube with Google Chrome.
Just click the Network tab, and then click the Size column header twice. This will cause the list to sort by size descending (you will see a down arrow next to where it says Size. You’ll notice that the largest file is listed at the top, and it is called videoplayback.
In this screenshot, you see there are two files called videoplayback. The second one was an advertisement I did not care to watch and skipped, which is why you see it in red with a status of (cancelled). To download the video, right-click on the file you want to save, and then click Open Link in New Tab. This will actually save the file to your downloads directory.
You may want to rename the file to something a bit more memorable than videoplayback, and even add the .flv extension to the end of the filename. You can play back the saved file with a great, free video player called VLC, which is available on Windows, Mac, and Linux. Consequently… This process of downloading flash videos will work with other sites as well as YouTube. Just look for the largest file on the page, save it, and play it back with VLC.
