The bad blood between both artists sparked after they got into an argument on Angie Martinez's Hot 97 radio show two weeks ago.
Cam would respond the following day with "Cuurtis," which took shots at 50's appearance and stressed that the G-Unit honcho is a snitch.
The footage shows Cam'ron rapping in front of a Harlem building surrounded by a crowd echoing "Cuurtis".
"It's official, we don't call the police 'squalie' no more, we call them Curtis," says the video's narrator pointing at a police car near the taping of the clip.
"Jay-Z bodied, Nasir bodied, Mase bodied, Curtis bodied," Cam'ron told DJ Kay Slay in a recent radio interview after his diss song hit airwaves. "The Curtis thing really got to him. He gotta do something now, I'm ready to go."
