RM (RealMedia) is the proprietary streaming format from RealNetworks (1997-2005), encoding video at 100-300 kbps for dial-up internet delivery at resolutions of 176x144 to 320x240. The Mobile Video device preset is a universal mobile profile producing H.264 Baseline at 480p in MP4 — designed for playback on any mobile device regardless of platform.
RM's original design was itself a mobile-bandwidth format — optimized for the 56 kbps dial-up connections that were the mobile internet of their era. Converting RM to the Mobile preset bridges two generations of constrained-bandwidth media, taking content from dial-up modems to cellular networks.
No mobile device can play RM files. The RealMedia container and codecs are extinct from consumer software. The Mobile preset converts to the most universally compatible format: H.264 Baseline MP4 at the source resolution. Since RM files are already below 480p, the Mobile preset preserves the original dimensions rather than upscaling.
The converted files are extraordinarily small — under 20 MB for most clips. This makes them practical for Bluetooth sharing, MMS, and transfer over the slowest connections. RM content was designed for minimal bandwidth, and the converted MP4 files inherit that compactness.
FFmpeg demuxes the RM container, decodes RealVideo, and re-encodes to H.264 Baseline Profile Level 3.0 at the source resolution (typically 176x144 to 320x240). Audio is decoded from RealAudio Cook and re-encoded to AAC-LC at 64-96 kbps. Video bitrate targets 200-400 kbps. The MP4 container includes faststart. The output plays on any device manufactured in the last 15 years.
RM source quality is inherently low — dial-up-era encoding produced blocky video with narrow-band audio. The Mobile preset preserves this quality without improvement. H.264 at matching bitrate may produce marginally fewer artifacts than RealVideo. On phone screens, the content is watchable for its historical value. Files are 5-20 MB per clip.
