.RMVB File Extension

An RMVB file is a Real Media video file compressed using a variable bitrate, 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.

You can open RMVB files with a variety of free media players, including RealNetworks RealPlayer (Windows), VLC media player (multiplatform), and GRETECH GOM Player (Windows).
