Technical analysis: Video Encoding and encapsulation formats

is often used to encapsulate rv40 Based on x264. This encoding bit rate does not significantly improve the image quality, therefore, the online HD videos with a 2 Mbps bit rate of about 2 GB are rmvb .; MP4 adopts the baseline and mainline encoding of MPEG4, which features a higher compression ratio and a smaller size. However, it is suitable for devices with low resolution such as MP4 players; of course, WMV encapsulates Microsoft's own files. As mentioned above, there are not many people usin
