The different methods to derive the jet velocity and orientation on the parsec scale are presented. From these methods I will discuss the velocity distribution of parsec scale jets and the possible presence of acceleration or deceleration in the jet velocity. Moreover, evidences of jet velocity structures will be reported. Finally I will present new data on the superluminal giant radio source 1144+35 to discuss in detail the properties of pc scale jets.
