To download any video from Youtube you should insert “ss” between “www.” and “youtube” in a browser address line.
For instance, you want to download Carlos Gavito workshop from www.youtube.com/watch?v=CZ2QnSpV7hs.
Type SS just before “youtube”, so it looks like: www.SSyoutube.com/watch?v=CZ2QnSpV7hs.
Press Enter. Then you see SaveFrom.net page, give it several seconds to find and suggest all accessible file formats.
Choose the format you like and downloan it at your hard drive.
The SS-trick works with Facebook as well.
P.S. You do not need to install any software the SaveFrom suggests )
