Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
I legit can't find any other source. I think the problem is that it looks like it would take at least 3 seconds for the rings to get back to the start and the jumping seems to happen about every second, so it looks like the gif doesn't get a chance to finish before starting again :(
