An apparatus and method are disclosed for transcoding a compressed video stream. In one embodiment, a compressed video stream is decoded. A spatial resolution of the decoded video stream can then be dynamically modified. The video stream with the modified spatial resolution can be re-encoded and transmitted over a network for display on a client device. The spatial resolution can be dynamically modified based on a variety of techniques. For example, a current bitrate and quantization parameters associated with the frames can be used to determine the spatial resolution. Alternatively, the spatial and/or temporal complexity can be used to modify spatial resolution.
