First, let me say that I didn't watch any of the videos.
There is no answer, other than the smart-alecky one that the best action is the one that the fish will respond to at any given time. You sort of answered your own question when you referred to the mood of the fish. At any given time, fish might respond to different actions than at other times. You can look at your lure or test it in a pool, or whatever, and decide what looks like the liveliest, or best, to you, but that's not necessarily what the fish is looking for.
