The target bit rate for a video that is to be transported across a network to a receiver is typically determined by the maximum throughput of the network. Such an approach is incognizant of the statistical properties of the video source and can result in inefficient use of bandwidth and/or compute resources. This disclosure describes techniques, based on the rate-distortion curve of the video source and encoder, to determine an ideal maximum bit rate for a video encoder, e.g., a bit rate that produces excellent video quality without undue load on network or compute resources. The techniques automatically adapt to and account for statistical parameters of the video source such as spatial resolution, frame rate, source complexity, etc. The techniques are applicable to a wide variety of video encoder types.
