When your primary concern is the file size you use 2-pass VBR encoding. You're saying I don't care what the quality is, I want a file of THIS size.. Because file_size = bitrate * running_time.When your primary concern is quality you use constant quality encoding.riginally Posted by iqbal88 Dear friends, Pls, discuss about what is the real difference between 1 pass encoding & 2 pass encoding In one word, the real difference between the two is quality.
The Aschelminthes (also known as Aeschelminthes), closely associated with the Platyhelminthes, are an obsolete phylum of pseudocoelomate and other similar animals that are no longer considered closely related and have been promoted to phyla in their own right.he term Aschelminth is now generally only used as an informal name for any member of the approximately ten different invertebrate phyla formerly included within Aschelminthes.
In biology, a phylum (/ËfaÉªlÉm/ ; plural: phyla) is a taxonomic rank below kingdom and above class. Traditionally, in botany the term division was used instead of phylum, although from 1993 the International Code of Nomenclature for algae, fungi, and plants accepted the designation phylum.urthermore, organisms in the stem group of a phylum can possess the body plan of the phylum without all the characteristics necessary to fall within it.
