RMV (RealMedia Video) or RMVB (RealMedia Variable Bitrate) is a proprietary video format developed by RealNetworks, Inc. It was widely used in the early 2000s for streaming and playing multimedia content over the internet, with the file extension rv, rmv, or rmvb. AVI (Audio Video Interleave) is a popular multimedia container format that was introduced by Microsoft in 1992.
The popularity of the RMV format has diminished over the years due to its limitations. For example, the RMV format is not compatible with most media players, making it difficult to play RMV files on popular media players like Windows Media Player, VLC, QuickTime, etc. Also, most video editing software does not support the RMV format, which makes it difficult to edit RMV files. On the contrary, AVI is compatible with most media players and video editing software. This has led to the need for converting RMV files to a more widely supported format like AVI.
The good news is that there are many converters available that can help you achieve your goals. In this article, we'll look at the top 4 RMV to AVI converters and compare their features, pros, and cons.
