A method, apparatus and computer program product for providing transmittal of pre-encoded video is presented. A video sequence is encoded with a first set of parameters to produce a first pre-encoded video. The video sequence is then encoded with a second set of parameters to produce a second pre-encoded video, the second set of parameters different than the first set of parameters. The first pre-encoded video is transmitted and, during transmittal of said first pre-encoded video, a switch is made to the second pre-encoded video at an intra encoding point such that no visual disturbance is perceived by a receiver of said pre-encoded videos.
