RMVB File - What Is an RMVB File and How Do I Open It

Is your RMVB file not opening on your media player? The thing is that most desktop media players like Windows Media Player and QuickTime Player don't offer native support for this file format. But fret not because there are several solutions to this problem. First, you can install an RMVB player to open any media format you may have. Or, you can losslessly convert RMVB to MP4 and enjoy playback on any platform or media player. So let's discuss these solutions!

Part 1. What is an RMVB File?

Let's first get an overview of the RMVB file format. Basically, RMVB (RealMedia Variable Bitrate) is a bitrate extension for the RealMedia container format created by RealNetworks. So, in short, RMVB is not a container format but rather a streaming media encoded in variable bitrate instead of the average bitrate. RMVB files have a filename extension of .rmvb.

That said, RMVB uses MPEG-4 Part 10 or compression algorithm. This gives it a smaller file size, lower bitrate, and better quality than, let's say, DivX. To play RMVB on Windows, you'll have to install the Real Alternative codec pack or get a compatible media player. RMVB-supported media players include VLC, RealPlayer, 5KPlayer, and more. We'll discuss that in the next section.
