Nullsoft Video (NSV) is a file and bitstream format designed to encapsulate generic audio and video together. NSV is intended to be flexible, efficient, and widely supported. Some key features of NSV are:

• NSV supports nearly any combination of audio and video compressor.
• NSV is a bitstream format, meaning that it has no requirement of a whole file or beginning of file to achieve play back. If you have the middle 1/3 of a 30 minute .NSV file, you can play back approximately 10 minutes of the contents.
• NSV's bitstream format is suitable for streaming; accurate synchronization can be acquired at any point in the stream.
• NSV supports auxiliary data chunks for sending multiple audio tracks, subtitles, or other data.

NSV was developed by Nullsoft corporation, the same company that produced the popular Winamp and Shoutcast streaming audio software.

NSV consists of free software to encode, stream and view video. There are additional third party NSV applications being developed and distributed by stations and users. Additional software can be purchased from outside commercial software vendors as well.

NSV was one of the first to break the restrictive Internet video broadcast barrier and allows anyone the ability to produce and distribute live or recorded video content.
