Techniques for dynamic GOP in video encoding are proposed in this paper. Comparing to the average-sampling of current standard fixed GOP structure, with dynamic GOP the encoder has great freedom in I-, P- and B-frame selection. The dynamic GOP structure keeps temporal importance information of frames in the encoded video, which helps in adaptation to bandwidth decrease and temporal-SNR quality tradeoff decision. It also helps in storing more information with restricted resource, results in code efficiency increasing and better user perception. An effective temporal importance metric is also proposed in this paper. The results are validated by experiments.
