The invention discloses a method and a device for processing video conversion coding from MPEG2 or H.263 format to H.264 format. Including: energy judgment procedures will read macroblock residual energy and threshold of video data is compared; if the sub macro blocks of the residual energy is less than or equal to threshold, perform first processing; if the macroblock residual energy is greater than the threshold, then the implementation of the second treatment; the first treatment of Acer in P16x16, P16x8, P8x16 block or P8x8 range selection of inter prediction modes, the follow-up can be chosen according to inter prediction model for estimating the motion of macro block; second: treatment of macroblock re motion estimation, the frame macroblock prediction mode, from the frame of the optimal prediction inter prediction mode and motion vector re selection mode, to select the inter prediction mode of macroblock motion estimation. The method has high conversion efficiency and good quality.

【技术保护点】
１．一种从ＭＰＥＧ２或Ｈ．２６３格式到Ｈ．２６４格式的视频转换编码的处理方法，其特征在于，包括：能量判断步骤，将所读取的一帧ＭＰＥＧ２格式或Ｈ．２６３格式的视频数据的宏块的残差能量与判定阈值相比较；若比较结果为宏块中的各子块的残差能量均小于或等于判定阈值，则执行第一处理步骤；若比较结果为宏块中的残差能量大于判定阈值，则执行第二处理步骤；第一处理步骤，对所述宏块在Ｐ１６ｘ１６帧间预测模式、Ｐ１６ｘ８帧间预测模式、Ｐ８ｘ１６帧间预测模式和Ｐ８ｘ８帧间预测模式范围内选择帧间预测模式，使得后续能根据选择的帧间预测模式对所述宏块进行运动估计处理；第二处理步骤，对所述宏块重新进行运动估...
