In addition to the most original single revaluation stream compression (1-pass CBR), XviD includes two dual (2-pass) dynamic code stream compression modes including single weight mass mode dynamic code flow compression, single weighting (quantization) mode dynamic code flow compression, and both external control and internal control 。 XviD is clearly the most MPEG4 coding core in th

The last computer architecture of this week was completed yesterday. I moved back to my house because I couldn't stand the sultry nature of my school dormitory. Near the third ring in the night, the sky is overcast, but it is a good sign of rain. When the sky was raining, a water drop hit me through the window. Long-time rain, In the sultry nature of Chengdu in September, I felt a little excited.
In fact, Chengdu in September is also a rainy season, but it may not be worth mentioning compared wi

compression ratio is average. The latest MPEG4 video encoding is Xvid, and the older DivX. h264 (x264 is a type of h264) is a new video encoding. It is common in HD videos and has a high compression ratio. However, it requires a high computing capability and high requirements on computer configuration. Vc1 is a new generation of video encoding launched by Microsoft, which is similar to h264.
According to the compression ratio comparison, for the same
