Based on motion vector field adaptive search algorithm,proposed an improvement on motion vector field adaptive search algorithm.Through the analysis of the motion vector field adaptive search algorithm,for its shortcomings,proposed an improvement on motion vector field adaptive search algorithm.The improved algorithm used effective early termination strategy,that setting dynamic threshold,fully used the video sequence of space and time correlation to divide the block type,and introduced the different search strategies to predict the starting point.By predicting the starting point,early termination strategy and dividing the block type the improved algorithm can effectively deal with the video sequence.Experiments show that image quality was slightly improved,the improved algorithm could effectively improve the encoding speed.
