That video is Guitar Pro, and no because there is no set way to finger things...That's really not that hard to figure out on your own. You've only got 4 fingers to work with, so I think you should be fine.

You can set the fingerings but arent going to find much music out there that does have the fingerings. The fingerings is on the bottom where all the bends, etc is its to the right looks like a hand with one finger sticking out. The fret board does that if you have it on and play whatever track is selected.
