Scripted style videos no matter the company are just that scripted more often than not they run through a dry version like a dance scene then when both are ready go to action, the cost of models range between 100 -500 an hour obviously the pros like Danni Ashe and big names are the high end to hire, every video gets edited for time, Napali video uses a loop over cut editing, if you watch their vids close you will see the same scene replayed 2-3 times from different angle, in short he can make a 15 minute video into an hour and costs half to make, after filming, editing the dvds are mass produced for sale, the closest thing you will ever see to rules catfighting is Tanya kicks or Vera , like was mentioned if you arrange a street fight , film and sell it you are looking at charges against you for instigating riot, public nuisance, and 3rd party aggravated assault, even if the participants sign waivers you are facing charges cause the states gaming commission will never issue a permit or license for illegal contact sport, when MMA / cage fighting first hit the media it was shut down for non licensed participation
