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.
M4V is a file format developed by Apple for the iTunes store's content and is very similar to the MP4 file extension. M4V is supported exclusively by Apple devices. Other video formats like MP4 and MOV can be converted to M4V in order to run on Apple devices. The most common difference between the M4V and MP4 formats is that M4V offers DRM-Copyright Protection which prevents the copyright of media content. To play a DRM-protected M4V file the computer needs authorization by opening the iTunes account used for buying the media file. However, if the files are not protected by DRM, the user can just rename the file extension from M4V to MP4 in order for it to be recognized by non-apple devices.
FreeFileConvert uses tuned encoding for RM to M4V 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 M4V 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 M4V 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.
The M4V makes use of both the H.264 and MPEG-4 video codecs. It is similar to the MP4 file format and its structure is based on the QuickTime media file format. M4V files use M4V extension similar to how extensions are used in MP4 file formats. The audio encoding in M4V is also the same as MP4 files and features lossless encoding, scalable lossless coding, MP3, MP2, MP1, CELP, HVXC, TWINVQ, TTSI (Text to Speech Interface) and SAOL (Structured Audio Orchestra Language).
