Need a vid dloader

[Odin]

Ok so i need a video downloader for downloading off youtoube, all the ones i used to use no longer work. I can still rip the sound but not the vid, last vid i was able to get was the robin thicke one with (blurred lines) with all the naked chicks. If anyone could help i would really appreciate it.
