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.
The Windows Media Video (or WMV) file format and its associated .wmv filename extension was first released to the public in 1999. It was a proprietary video stream wrapper developed by Microsoft as part of their ASF multimedia container. As of writing, WMV is no longer considered proprietary, since WMV 9 gained standardization as an open standard in the SMPTE 421M specification as VC-1. WMV supports a combination of both audio and video bit streams compressed using one of Microsoft's associated codecs. Also supported is windows media digital rights management for video content.
FreeFileConvert uses tuned encoding for RMVB to WMV 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 WMV 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 WMV 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.
WMV in its initial form was Microsoft's implementation of the MPEG-2 Part 2 specification, but has since undergone several revisions, becoming the adopted format for digital video deliver over HD DVD and Blue Ray optical mediums. The format supports high definition video with resolution of up to 1080p.
