The following review written by one of the Software Informer contributors applies to version 2011.8
Final Video Downloader is a great application which provides you with the function of downloading videos from YouTube. The program automatically integrates with your web browser, so you just have to click on the 'Add video link' button to start downloading your favorite clips. This powerful software enables you to download many videos at once and it will do it in a couple of minutes. The application also provides you with the function of converting downloaded files into Mp4, AVI, WMV and Mp3 files. I used this application to download one of my favorite video clips and saved it in Mp4 as the output format and it worked perfectly. Besides, it only took me three minutes to download the whole video. By converting your files into the Mp4 format, you will be able to transfer them to many portable devices, including the iPod and the PSP Player. Also, you can use this program to download only the audio from your favorite videos on YouTube. The graphic interface of this program is very intuitive. Before converting your files, you can set any output folder to save your files to.
I think this application is great, because it allows you to download videos from YouTube in an easy way and it's completely free.
