If you want Disney quality you need to watch Disney movies. Unfortunately they don't let Pluto do zoo movies.
I was at a Hollywood movie set once, for a minor scene of probably 45 seconds duration in the movie "The Legend of Beggar Vance". Not exactly a high budget movie.
They had 6 camera guys with two assistants each, about a million bucks in camera equipment, truckloads of Arri lights, a generator truck, about 5 semi trucks, 10 RVs, and probably about 50 people running around, besides the actors.
Ever tried to film dog mounting with a 800 bucks camcorder and a cheap video light? I have. Didn't turn out to well. That's why it's called amateur, and that's why the quality sucks, because most zoo couples don't have a $ 120 million budget for their clips. That's also why you can download their stuff for free and don't risk much. Try disrtributing Disney's new Ratatoiuille movie through a free server, they hunt your ass down and shove a multi million dollar lawsuit up your ass.
