Any Video Converter. 2 pass encoding, one of the multi-pass encoding, is a technique for encoding video into another format using two passes to keep the best quality. Any Video Converter provides 1 or 2 encode pass for you to choose when you are converting video to MPEG 2 or MP4.Two pass encoding produces much better results than one pass encoding. But there are certain disadvantages of this technique. Two pass coding is almost twice slower than one-pass coding.wo-pass encoding will not make such mistakes. Using statistics of the 1st pass the encoder can estimate the value of each frame in bits. It results in a better distribution of bits between two parts of the video clip. The first dynamic part will get more bits while the second part will get less bits.
Phyllite is formed by relatively low-grade metamorphic conditions in the lower part of the greenschist facies. Parent rocks may be only partially metamorphosed so that the original mineralogy and sedimentary bedding are partially preserved.HYLLITE. Phyllite is a fine-grained metamorphic rock formed by the low grade metamorphism of fine-grained, sedimentary rocks, such as mudstones or shales.
There are two basic types of metamorphic rocks. Foliated metamorphic rocks such as gneiss, phyllite, schist, and slate have a layered or banded appearance that is produced by exposure to heat and directed pressure.on-foliated metamorphic rocks such as hornfels, marble, quartzite, and novaculite do not have a layered or banded appearance. Pictures and brief descriptions of some common types of metamorphic rocks are shown on this page.
