The .rmvb filename extension refers to the RealMedia variable bitrate format which is an extension of the RealMedia multimedia container format. RMVB is a proprietary multimedia digital container developed and maintained by RealNetworks, an internet streaming Media Company. It is different from its closely related format .rm in that it was designed for distribution of complete multimedia content, however it does support real-time media streaming. Video and Audio streams can be encoded and packaged into this format and distributed as single files for later playback on compatible devices and software as opposed to file streaming on high bandwidth networks.
Some confusion exists in whether there is an underlying difference between the filename extension .mpg and .mpeg. The short answer is there is no difference. Both filename extensions refer to one of two MPEG standards either MPEG-1 or MPEG-2. The reason for the confusion has its history in how early versions of windows enforced a maximum of three characters for filename extensions whereas Mac OS did not have such limitations. Thus on windows the mpeg file format was referred to using the .mpg filename extension whereas on Mac OS the filename extension .mpg and .mpeg was used interchangeably but referred to the same file format. The format is still the most broadly compatible audio and video container format from the lossy class of containers. The MPEG standard is supported by numerous audio and video products and software applications.
FreeFileConvert uses tuned encoding for RMVB to MPG conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload RMVB files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized MPG 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 MPG audio with dependable progress tracking.
.rmvb files use proprietary video and audio compression encoding formats comparable to the MPEG-4 Part 10 standard such as H.264/MPEG-4 AVC format. Byte ordering for the RMVB format is big endian and consists of a series of chunks. The first chunk is always the real media file header.
The mpeg-1 file format extension is standardized in ISO/IEC 11172. It was extended from the H.261 and JPEG file formats and is capable of scaling down VHS video at a ratio of 26:1 and CD audio at a ratio of 6:1. The format allows for transcoding of video and associated audio to a maximum bitrate of 1.5 Mbit/second. The mpeg-2 format further builds upon the mpeg-1 format and is standardized in ISO/IEC 13818. Mpeg-2 adds support for interlaced video, a feature that did not exist in the previous format mpeg-1. The .mpg filename extension can refer to any one of the two formats.
