In order to transmit a huge amount of video data over the bandwidth-limited channels, we often do frame skipping in the encoder and use MCFI to interpolate the frame in the decoder. But the quality of interpolated frame is not good, because we don’t have the original skipped frame information in the decoder. So we propose the advanced motion compensated frame interpolation (AMCFI) to improve the problem. In the encoder, we improve the quality of interpolated frame by using the original skipped frame information to do some processes such as motion vector refinement and weighted motion compensation which are used to solve the interpolated frame’s visual effect in the decoder. We also can find that AMCFI reduce coding time in the encoder, so we will propose two advanced video coding technics to reduce coding time.
