Fortunately, this article will give you all the best tutorials you can follow to convert your RM files to MP4 perfectly. With that, you can ensure that you can have satisfying video playback. Thus, you can start reading this post and explore the best ways to convert RM to MP4.

Part 1. What is an RM File

The RM format, known as RealMedia, is a proprietary container format developed and designed by RealNetworks. Its main purpose is for streaming audio and video over the Internet during the dial-up era. It was revolutionary for its time. It uses highly efficient compression to provide watchable content over very low-bandwidth connections. However, its codecs are now considered obsolete and offer poor quality compared to modern standards. Due to its proprietary nature and lack of native support on contemporary devices and operating systems, RM files are largely incompatible with today's media players. With that, if you still want to watch the content from the file, it would be better to change its format, from RM to MP4, which is the most supported format in this modern era.
