H.264 Video transcoding Motion vector composition algorithms
In temporal transcoding, motion vector composition algorithms are used to reduce the computation time of the transcoding process. In this paper, we propose a multi-level motion vector composition scheme for H.264 transcoding, with the Bilinear Interpolation (BI) function. Simulation results show that the proposed algorithm achieves a video quality comparable with that of the motion estimation process with the advantage of greatly reducing the computation time of transcoding.
