RM文件是以RealNetworks公司开发的RealMedia容器格式存储的多媒体文件。RM文件通常用于在互联网上传输内容，如视频和互联网广播。
RM格式是当前数字内容世界中的一个多媒体标准。而它显示出以下的优点和缺点。
用户通常用RealPlayer软件播放RM媒体文件，但他们也可以用其他音频程序打开，如Eltima Elmedia Player或GRETECH GOM Player。VideoLAN的VLC媒体播放器也可以用来播放RM文件，但这个软件只提供对该格式的部分支持。
RM format guide
RM is a RealMedia container used for older streaming audio and video with Real codecs.
Convertr uses the deployed FFmpeg toolchain for published audio and video routes. A container such as MP4, MOV, MKV, AVI, or WebM can hold different codecs, so the file extension alone does not guarantee that a particular player will accept the contents.
Convert readable RM files to MP4 for current playback.
The public upload limit is 1 GB. Convertr does not reduce dimensions, duration, resolution, or output quality merely to manage worker load.
Keep the original dimensions and frame rate unless you intentionally need a smaller result. Remuxing compatible streams avoids re-encoding; changing codecs is lossy, so repeated conversions should be avoided.
Some proprietary Real codecs, damaged indexes, and streaming references may not decode.
These links come from the active conversion catalog, not from a generic list of possible formats.
Choose one of these implemented routes; a listed extension is not a promise that every codec variant will decode.
Check that the file opens in its original application, is not encrypted or DRM-protected, and really matches its extension. A damaged header, unsupported internal codec, missing linked asset, or mislabeled file can fail even when RM is generally supported. Try a different published target only when it fits your goal; changing the extension by hand does not convert the file.
