How do I convert RM files to MKV using LetsConvert?

Upload your RM file to the converter, select MKV as the output container, pick a modern codec like H.264 or HEVC for the video track, and choose your preferred resolution and bitrate. Click 'Convert'. Once done, download the MKV file. The whole process preserves the original audio track unless you opt for advanced settings.

Why should I convert RM to MKV instead of keeping it as RM?

RM files use RealVideo codec, which is outdated and poorly supported by modern players and devices. MKV is a highly flexible container that supports H.264/HEVC, multiple audio tracks, subtitles, chapters, and metadata. Converting RM to MKV ensures compatibility with VLC, Kodi, smart TVs, and mobile devices, and often yields better compression at the same quality. It also allows you to archive your media with advanced features like embedded subtitles and multiple language tracks.

What happens to the video and audio quality during RM to MKV conversion?

RM files typically contain RealVideo and RealAudio streams. When converting to MKV, the tool re-encodes these streams into modern codecs (e.g., H.264/HEVC for video, AAC for audio). You can choose a lossless or high-bitrate setting to minimize generation loss. The resolution, frame rate, and duration are preserved. Subtitles and chapter information are extracted and inserted into the MKV container when present, though some RM-specific metadata may not carry over due to codec differences.
