%X In order to obtain accurate frame-level target bit allocation and improve encoding quality,this paper presented an adaptive frame-level optimal scheme of bit allocation.This algorithm made full use of texture complexity between frames compensating the inadequacy of average bit allocation scheme in JVT-G012 rate control algorithm. Extensive experimental results show that the proposed algorithm under the circmstances of high-movement or scene change, can significantly enhance the quality of video encoding and achieve the goal of optimizing bit allocation.
