Can you explain JF or Just Frame? At what frame exactly the character becomes shiny? I looked but couldn't find details about this.
A "just frame" is a special move involed usually in a combo of some kind. With a precise input of the correct command, your character will flash "shiny" as you put it. Depending on the character it can do a few things for you. It usually gives you advantages of frames, leads into more damaging combos and things of that nature.
There are Just Ukemi's also. If your oppenent hits you in a way that forces you to the ground. If you hit G and the exact time you either get hit with it, or hit the ground. You will flash and be standing up. Not that that move gives you much advantage, but it will allow you to block faster and not get hit with the rest of the combo you were about to recieve.
