Windows Media Video (WMV) is a video format and is a part of Advanced Systems Format (asf) container. Microsoft developed this format. WMV files can be facilitated by a variety of Operating Systems such as Mac as well as the PC. A few WMV files also have the digits right management (DRM) protection, so unauthorized can't make copies of the recordings, basically the ones purchased from an online store.

The exclusive codecs developed by Microsoft can be obtained while a WMV file is compressed. Users can use Windows Media Video 9 Professional. It allows them to play their respective file at resolutions surpassing 300,000 pixels (having a screen resolution as low as 528x576) with an exceptional bit rate of 1000 Kbit/s. The high definition abilities make WMV files an ideal choice for HD DVD and Blu-ray disks. WMV 9 format is the one you should be looking for, and it is also comparable to H.264 Main and High Profile. It does not support various activities, such as multiple reference frames and context-adaptive binary arithmetic coding (CABAC). Lower bit-rates can reveal the differences between WMV and its competitors.

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.

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.
