Abstract
A system () and method () for efficient video adaptation of an input video () is provided. The method can include segmenting () the input video into a plurality of video shots () using a video trace () to exploit a temporal structure of the input video, selecting () a subset of frames () for the video shots that minimizes a distortion of adapted video () using the video trace, and selecting transcoding parameters () for the subset of frames to produce an optimal video quality of the adapted video under constraints of frame rate, bit rate, and viewing time constraint. The video trace is a compact representation for temporal and spatial distortions for frames in the input video. A spatio-temporal rate-distortion model () provides selection of the transcoding parameters during adaptation.
