About RM and WEBM

.rmRealMedia

application/vnd.rn-realmedia

Multimedia container format created by RealNetworks, commonly used for streaming content in the late 90s and 2000s.

.webmWebM Video

video/webm

WebM is an audiovisual media file format. It is primarily intended to offer a royalty-free alternative to use in the HTML5 video tag. It utilizes the VP8 or VP9 video codecs and Vorbis or Opus audio codecs.

Conversion Notes

Video conversion re-encodes both the video and audio streams to fit the target container and codec. Resolution, frame rate, and aspect ratio are preserved by default. If the source uses a codec not natively supported by WEBM, a compatibility codec is chosen automatically. Conversion time scales with file duration and resolution — 4K files may take several minutes to process.
