Information about MP4 and RMVB file formats

Full name MP4 - MPEG-4 Part 14 RealMedia Variable Bit Rate File
File extension .mp4, .m4a, .m4p, .m4b, .m4r, .m4v .rmvb
MIME type video/mp4 application/vnd.rn-realmedia-vbr

Type of format Media container Video File
Description MPEG-4 Part 14 or MP4 is a digital multimedia format most commonly used to store video and audio and store other data such as subtitles and still images. Like most modern container formats, it allows streaming over the Internet. RMVB is a file type developed by Real Networks and stands for RealMedia Variable Bit Rate file. RMVB is similar to MPEG4 files and differs from the RealMedia format, which encodes at a constant value. XVID and DIVX are other types of variable bitrate files. RMVB files are quite common in Asia but less prevalent in Europe and the Americas.
Technical details Most kinds of data can be embedded in MPEG-4 Part 14 files through private streams. A separate hint track is used to include streaming information in the file. Variable bit rate files alter the amount of data for a given amount of time. This allows the bitrate to be increased for more complex elements of the file and decreased for less complex parts. This means the storage requirements of the file are less, with a negligible decrease in image and audio quality. The disadvantage of this type of file is that the encoding process is longer than a constant bitrate file.
