.RMVB File Extension

An RMVB file is a Real Media video file compressed using a variable bit rate, which is optimized for the content of the video. It is a newer variation of the standard Real Media (.RM) file format that allows for more efficient compression.

RMVB files have become a popular format for Anime and Asian movie titles because they have smaller file sizes and lower bitrates with better quality compared to DivX (.DVX) files.
