RealNetworks, an internet streaming Media Company, is credited as the developers and owners of the proprietary RealMedia multimedia container format. The filename extension .rm refers to this format which is used as an audio and video wrapper to distribute digital media content over the internet. The first version of this container was released in 1997 and has been popularized for its ability to unpack the digital stream while it is being downloaded over computer networks such as the internet. The format is platform agnostic and works equally well on Microsoft Windows as it does on Linux or Mac OS.
The OGG file format and .ogg file extension refer to the open source container format developed and maintained by the Xiph.Org Foundation. The format has been in development since the early 90's and initially was designed as an open format for audio compression. Later iterations has seen the format revised into a full audio and video container format with compression codec support of different standards. OGG can be used both in compressed or uncompressed ways and is compatible with different lossy and lossless codecs both for audio and for video. Text can also be added into OGG files as an overlay, all packaged within a single file.
FreeFileConvert uses tuned encoding for RM to OGG conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload RM files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized OGG results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent OGG audio with dependable progress tracking.
Unlike RealMedia variable bitrate format, the RealMedia container format encodes streaming media at a constant bitrate. .rm files use proprietary video and audio compression encoding formats from the RealVideo and RealAudio suite of compression formats. Video stream encoding was upon its initial release based upon the H.263 compression format.
Though OGG is versatile in the number of codecs it supports, typically only free codecs developed by the Xiph.org organization are used for encoding and decoding. From the lossy family of codecs, audio can be encoded using Speex, Vorbis, or Opus. Whereas Lossless or uncompressed encoding can be done using FLAC and OggPCM respectively. To be competitive against its closest rivals such as Windows Media Video, Real Video and MPEG-4, lossy video compression codec Theora is often used but a lossless format, DIRAC, can also be used to encode video streams.
