Description
RMVB is a type of file that means the RealMedia Variable Bit Rate file and it’s made by Real Networks. The RMVB shares similar qualities with MPEG4 but its not the same from the RealMedia format that encodes at a constant value. Other variable bitrate files are DIVX and XVID. This file format is popular in Asia but less known in America and Europe.
Technical details
The compression of RMVB files is the same as the MPEG-4 part 10 encoders. The file type has remained unpopular because of its incompatibility with media players besides RealMedia. However, it is still very relevant in Asia. It is compatible with peer-to-peer sharing platforms and torrent programs. The amount of data in a set time frame can be altered by variable bit rate files. Therefore, there is less storage requirement with a decrease in quality but longer encoding process.
