方法/步骤 1 左键单击【文件】→【新建】→【序列】2 在【序列预设】→【可用预设】里的第二条，我们能找到AVC-Intra,这个是松下的机器编码出来的 3 左键单击【AVC-Intra】，能看到1080i，1080p，720p，这三个都是HD（高清）视频输出 4 720p：小高清1080p：高清，分辨率为1920*1080 5 AVC-I 100 1080i50...
Intra-frame俗称I帧,也就是帧内压缩,其记录方式是不管画面拍摄内容是什么,都要对每一帧进行压缩编码,一张白纸和一片草原的压缩率是一样的标准,因此,得到的画面品质更高,代价是文件较大,但是对于后期剪辑来说相对轻松,因为算法相对简单,解压缩的硬件负担...

The article focuses on codec board Advanced Video Coding (AVC)-I which is an intra-only version of AVC compression. High-speed networks are advantageous for broadcast contribution applications like content exchange, newsgathering and event broadcasting. To reduce the bit rate for transmiting video ...

In this paper, dynamic rate shaping for H.264/AVC intracoded video streams is investigated. An analysis of the distortion distinguishes different error components that lead to the degradation of the output video stream. Experimental results show that the propagation error due to intra prediction has...
The H.264/AVC baseline video coding uses several static Group Of Pictures (GOP) with fixed sizes that specify how the I (Intra) and P(Predictive) frames are positioned during the video coding process. This method aims to ameliorate the coding efficiency of H.264/AVC video coding and to ...
