Developed by Nullsoft, the makers of Winamp, Nullsoft Streaming Video (NSV) was a media container designed for streaming video content over the Internet. As one of those streaming video formats offered by various companies and media players, NSV, among Windows Media, QuickTime File Format and RealMedia streams, each have their benefits and shortcomings. NSV, by default configuration, used MP3 as its standard audio format, with VP3 as the video format. Various hacks and codec installations allowed NSV to use Ogg Vorbis for audio and later updates of the VP codecs for video. Many users might not be very familiar with NSV video. Here five NSV converters are introduced to convert NSV video. You can open and play NSV files as well.
