Abstract
Systems and methods of transcoding video bitstreams that employ highly efficient look-ahead approaches to video transcoding. The systems and methods perform video transcoding in the pixel domain to make successive adjustments to estimates of the coding complexity of video frames in input video bitstreams. The systems and methods can employ the adjusted estimates of the coding complexity in a rate control function to provide improved bit allocations for the video frames in transcoded output video bitstreams, thereby enhancing overall perceptual quality.
