Some of those took ages too, though.

While the majority of the videos there were first-attempt successes, some of them took numerous attempst before I finally won.

Omega Weapon took four or five attempts, Malboro Menace took a couple, Vorban holds the record at nearly 300 attempts before I finally beat him, Jumbo Flan was beaten the first time I tried to record it but I had lost to him before that while trying just to see if it was even possible, Fafnir took at least a dozen tries, Shinryu took about 50 (I got really lucky there - most people who've beaten him say it took them over a thousand tries), the first Dark Ixion battle took about a dozen, and the second two or three.

Then, you also have to consider the preparation time. My general armour for everyone was Ribbon, Auto-Haste, Auto-Phoenix, Auto-Regen. On top of that, for some specific battles, I used custom armour for Auron - usually HP+30%, HP+20%, Defence or Magic Defence+20% and either Auto-Phoenix or Auto-Potion, but the one I used for Catastrophe needed Ribbon on it. >_>

So, it's not something that can be done in 10 minutes... but when you get as experienced in the game as I am, it's mostly viable.
