Agree with a prior post, looks like a cam chain rail failure. Knock is likely heard at the back of the car right or left side of the engine fan. I doubt it's knocking on both sides, take a long screw driver put the handle against your ear and touch the end of the driver to the area near the chains. LHS behind the distributor and then RHS near the AC compressor. Does it sound a lot louder on one side?
