TMZ has obtained NEW VIDEO of the Chris Brown valet incident ... in which it's clear -- BROWN THREATENED THE VALET.

The new footage shows Chris cussing at the valet in front of PINZ bowling alley in Studio City, CA -- where Brown had just attended a charity event for inner city youth.

The valet had asked for the $10 fee before handing Brown the keys -- but Chris refused to pay because he was only at the event for a short time and didn't feel it was fair.

Chris exploded in anger ... getting right in the valet's face and yelling, "Gimme my f*cking keys ... f*ck ten dollars."

Then comes the threat -- "Gimme my keys ... we gonna turn this whole spot up ... I promise you."
