wayback machine internet archive

There's a video that was on Youtube that's no longer available there; but I found it on the Wayback Machine Internet Archive. I would like to save a copy of it, but 4kdownload can't decipher how to parse the youtube link within the archive's link...

(ie, http://web.archive.org/web/20160203131052/https://www.youtube.com/watch?v=b6IB0trJoJU)
