How Do I Change Visa Type

I cannot think of an appropriate visa for your friend from Brazil to change status to in order to do freelance video production unless he is good enough to qualify for O-1 extraordinary alien status. If not, he may wish to consult with an immigration lawyer to go over his options and what compromises he is willing to make with his goals if he is eligible to obtain some other type of visa status to remain in the country for a longer period of time.
