Abstract: H.264 achieves higher coding efficiency than other existing video coding standards greatly. But its high complexity is the difficultproblem. For bit rate video application, a rational profile is selected according to analysis of main encoder tools. Fast motion search method and integer transform are implemented by using SIMD technique.
