About this format
RealVideo format context
Format: RealVideo
Overview
RealVideo matters because it was one of the earliest practical streaming video codecs, enabling internet video delivery over dial-up and early broadband connections when few alternatives existed.
Late-1990s internet users needed a way to watch video over dial-up connections, requiring aggressive compression and progressive streaming capabilities that existing codecs did not offer.
RealVideo is now a legacy format; files persist in archives and older media collections, but the codec and streaming ecosystem have been entirely displaced by H.
RealVideo is closely associated with RealNetworks.
RealVideo is usually selected for workflows that center on editing, mastering, streaming delivery.
