Convert AVI to RMVB

.avi

Video Lan VLC Player

AVI stands for Audio and Video Interleave. It has an extension written as .avi, and users use this same format to store audio and video on their PC, which was developed by Microsoft in 1992 for its Video for Windows project. It allows the simultaneous playback by keeping video and audio into a single file. The simple architecture of .avi format will enable it to run on various operating systems such as Windows, Mac, Linux, Unix. It is supported by multiple web players as well.

AVI format uses Resource Interchange File Format (RIFF) support, where the real data is stored into chunks, and each chunk gets recognized by a FourCC tag. Out of these individual chunks, the first one can be recognized by the hdrl tag, and it can decode the chunk containing metadata for the video. The second chunk gets identified by the movi tag, and it includes the actual audio and visual data which makes up the AVI movie. It uses less compression rather than the MOV and MPEG file formats.

.rmvb

RealPlayer

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.
